Preventitive maintenance part two-idler pulley replacement and overflow bottle cleaning.

So with the tune up all finished and driving the duck around for a bit I found the noise from the idler pulley to be still there, and an inspection of the pulley led to a failed bearing.  After 226,000 miles it had definitely seen better days and was in need of replacement, before it locked up and spit the belt off the engine.

After again removing the serpentine belt, a 13 millimeter socket and ratchet remove the old idler pulley.  This being the original pulley, there was a large washer that was used as a dust cover, to keep dirt away from the bearing and therefore keeping the pulley in service longer.  On the replacement, the bearing is sealed, and the dust cover is not necessary, especially considering that the cover did not fit the pulley very well.  The replacement pulley came with an insert to keep the pulley at the proper distance from the mounting point on the engine block, and some Loctite blue keeps the factory bolt in place when reinstalling once cured, usually 24 hours for a complete curing.

A pointer on using Loctite: Loctite comes in three versions, which are color coded according to their use.  Loctite green is the lightest duty, and generally has no use that I am aware of in an automotive setting. Loctite red is the strongest duty, and is meant for use on something that you never want to come apart. Heat is required to break loose anything you decide to use the red strength for, and the red version is very unforgiving, so whatever you use this strength thread locker on plan to have it stay together forever.

Loctite blue is a good, all around keep it in place thread locker. You will need to use a proper wrench or other tool to break loose any bolts you apply this to, but it is forgiving in that you can actually take something apart without having to heat the bolt up to do so.  I use this on anything I really don't want to come apart at an inopportune moment, like the aforementioned idler pulley, the A/C compressor I removed during the tune up, and in the future, the differential cover bolts. 

I have not repaired the thermostat/upper radiator hose issue yet, but I did take notice that the coolant overflow tank has a lot of what looks like lime in it.  It's actually cooling system sludge, along with rust and other junk that almost proved impossible to remove.  Why clean the overflow bottle? Because you don't want that stuff to somehow make its way back into the rest of the cooling system, where it can clog up the radiator or whatever small passages exist.

I ended up using a combination of salt, water and ice cubes to clean the sludge off.  What you need to do is remove the overflow tank (engine must be cold) and empty anything that might be in said tank in a responsible manner.  You then add salt (about three tablespoons), some cold water (your goal is to make a slurry) and ice cubes.  Shake this mixture in the tank until you have removed as much of the crud as you can, then rinse well with hot water and reinstall.  The salt is abrasive enough to remove the deposits and the ice helps it move around in the tank, keeping your salty slurry on the target area.

Not sure at this moment what project I am going to tackle next, but I am thinking it will be the parking brake cable.

Preventive Maintenance part one...underhood.

So today I decided to take advantage of the unusually warm weather and complete the tune up I have wanted to do for awhile. For this service, I gathered four Autolite spark plugs, BWD distributor cap and rotor, a spark plug wire kit, a Purolator air filter (just a paper one because oiled filters won't help this engine enough to justify the expense), and a serpentine belt. I also used disposable gloves, dielectric grease, anti-seize compound, masking tape, a sharpie, and a can of throttle body cleaner.







Gee Mr. Dale, what are these parts for?

 It's tune up day here in Daleland, also known as ridding my truck of the evil troll spirits!  Follow along as I do a complete secondary ignition tune up, serpentine belt install, air filter change, and find a couple surprises along the way.

Ok so above you can see I am starting out with the engine all buttoned up...not bad for 226,000 plus miles.
All that air box and tubing that sits over the engine needs to come out of the engine bay.
 

 Like the caption says, all that air box tube and the big box itself had to come out.  The tube was fairly easy to get loose but the big box over the throttle body wanted to be difficult.  The tube is held on by hose clamps, but the box is held on by a clamp that needs to be loosened by pushing the end of the clamp back.

With the air box out of the way I can start checking things...first is the throttle body, which is to the right...
 

Holy crap did a troll take a dump in here?
I tried soaking the butterfly but that alone did not work, so I decided to tackle the rest of the tune up first.
 

 Ugh! No wonder the truck throttle felt a little off.  That brown slime is dirt and grime buildup that can make the throttle feel sticky during operation.  Gunk throttle body and air intake cleaner has two sets of directions, which boil down to engine off or engine on.  In either case wear safety glasses because something strong enough to clean out this stuff, which is technically called varnish, will probably do a number on your eyes. Considering how hard it is to get to the #1 spark plug, I decided to remove the serpentine belt and move the A/C compressor out of the way first.




Part of the tune up today was changing the serpentine belt.  On my truck, this bolt that
I am pointing at is what you loosen to move the tensioner and thereby loosen the belt.

To get to the number one spark plug I have found it easier to unbolt
and set the air conditioner compressor to the side, gently, leaving the lines attached.
Note the line separator, loosen but do not remove the nut in the center because you
have to move the metal line out of the way, slightly and gently, to get the bolt out of the a/c
compressor mount.

Here's a tip.  Use masking tape and a sharpie to label the plug wires.
Use masking tape to hold the plug onto the socket if needed.

With the A/C compressor moved along with the belt removed and out of the way, I removed the plug wires one at a time and tagged them.  The next step is to remove the old plugs and check them for any sort of contamination, such as oil or ash.

Before I installed the new plugs, I checked the gap and then adjusted it to 0.040 inches.  Dodge states that the gap should be 0.035 inches, but I have run a 0.040 inch gap previously on my 1986 Chrysler Laser with the same engine setup with no issues, except for better fuel economy.  In the middle of this part of the project I checked the accessory pulleys for noise and wear.  The idler pictured below is making noise when you spin it by hand so it will need to be replaced.  Then I noticed the coolant leaking around the thermostat housing. Looks like the upper radiator hose clamp might be loose, so I tightened it a little.


A little while back I was losing coolant.  Looks like this is the culprit area, which narrows
it down to hose, thermostat gasket or thermostat housing. I tightened the hose clamp but
in the future I will pressure test the cooling system to be certain.

So I think I found an issue...actually that is an issue that needs to be addressed...soon. The best bet might be to replace the hoses as soon as possible.

Its hard to see in this photo but the center of the rotor and the contact are worn.
The distributor cap was also worn down

 Something I want to stress at this point is that the number one on the distributor cap (not pictured) is so that the number one spark plug wire is routed to the proper plug.  The rotor rotates clockwise in the distributor cap and fires the cylinders in this order: 1,3,4,2.  The cylinders are (from the front of the engine where the belt lives) in order: 1,2,3,4. This firing order is pretty much the same for almost every four cylinder engine made in the United States.

Before reinstalling the serpentine belt I started the engine and let it run for a few minutes to check to see if the noise I was hearing was valve train or accessory related. I did hear some minor noise which I attribute to either injector noise or rocker arm adjustment needing to be done.  The belt also needs to "set" into the pulleys before driving it.  Additionally, you would rather the belt go flying off the engine at your home rather than out driving your vehicle around.


This is way better...
 

So, about that throttle body...I ended up first soaking a rag with throttle body cleaner and wiping off as much troll slime as I could get to.  Then I started the engine and cleaned the butterfly with short bursts while manually operating the throttle.  IMPORTANT: Never lean over the belts to do this service with the engine running.  Go from the side.  The belt and/or accessory pulley can catch your clothing and cause major injury, like taking your arm off.


The reason for cleaning your throttle body, mass air flow sensor, intake tube and anything else having to do with the intake and fuel systems is there is dirt and other junk flying around in the air most of the time.  This dirt can get into the engine without a good air filter and cause problems, like making the throttle body butterfly stick closed, hard throttle movement, bad fuel economy, and in general lackluster performance.

One of the conveniences of owning a truck is that if you need to remove parts usually you can store them in the bed.  This being said I will probably end up painting these components sometime in the future, just to keep the engine bay looking good.  Ok as good as it can considering the truck started life red and received a paint job that did not carry into anything that is usually not seen by the general public.

So, after doing all this work (took about two hours) the truck is definitely running better.  Before the tune up the truck would move but it seemed to be sluggish at times.  Now, the throttle response is better, the acceleration is improved, and just overall it feels like there is more power available.  I still have to tackle the coolant leak and I still have to see what, if anything, is going on under the valve cover. 



Toolboxes anew and the progress so far.

First off, the shopping list for the duck is about halfway done, with fluids and a couple more filters still needing to be purchased.  Now I just need a warm day or a warm garage to get all this going.  I still have time, I just want this done and out of the way.

Speaking of getting things out of the way, I have spent almost a year trying to get a new toolbox.  The biggest problems with getting one have been about the time I have the money together, something else needs attention or the one I ultimately purchased was not in stock.

If you have ever seriously looked for a decent box, you will find that many of the higher end boxes have higher end prices.  Snap on boxes, for example, run into the thousands of dollars.  Mac is kind of expensive as well, and while Kobalt is nice, stainless steel is just not something I want to mess with trying to keep it bright and shiny.

I had specific things I was looking for, such as 100 pound drawer capacity, 41 inches wide, not some god awful color (like hot neon pink) and not so expensive as to rival the combined national debt of the European Union.  I ultimately decided on a Kodiak Pro Elite 41 inch tool chest which I bought through Home Depot.

First, their website says it will take up to two weeks plus processing time to get it shipped to my local Home Depot.  So, you can imagine my surprise when it was at the store in under a week.  The box was well packaged, wrapped in plastic over cardboard and had a pallet thing under it for ease of loading with a forklift.  The friendly folks at home depot were kind enough to send a couple of guys to help me get it into the duck.  I strapped it down and was on my way.

In between excitement of finally getting the box I have wanted for awhile, parking my truck on a public street, worrying about the local riff raff trying to steal it and it being about zero degrees with snow on the way, not much sleep was to be had for me.  I think I must have checked on the box a couple dozen times before I went to sleep.

Morning comes and the box is still there, so off to work I go.  After working my shift I unloaded the new toolbox, with the help of my boss (something that would NEVER happen at my last job) and got to work setting it up.  There was a hole in the cardboard, and I thought for a moment that it would totally suck if I had to take this heavy thing back, but after unbolting the pallet and removing the coverings, no damage was found.

I am not going to bore you with the details of loading the box with my tools, but I will say the smart individual reads the instructions for assembly, is grateful the casters are preinstalled, and loads the box from the bottom drawers up, with the heaviest items in the bottom so the box is not likely to tip over.

I also learned that when you place items in a box that is the same size as the old one, and you go to place the tools in the new box in a neat manner, you find that the top box is looking like a good option, one I will be taking in the near future.

Some customization ideas...since I have to do some repairs as it is...

So I was thinking that after I get the maintenance all squared away that I could start making some changes to the duck, and one of them is going to be replacing a slightly dented fender, which got dented when someone in the employ of the previous owner hit something and caved in the front bumper a little bit.  The other is replacing the front bumper, but I was thinking about doing something a little different that you don't see a whole lot these days, a shaved bumper.

So, what is a shaved bumper?

Shaving a bumper is the process of making it look like it is one solid piece of steel. There are bumper covers that are made out of fiberglass that frankly try to make this happen, but as it is they are plastic, and plastic does not look right on a truck.  What you would do is weld the mounting bolts to the bumper from the backside, then grind the heads off of the bolts from the face of the bumper, fill in the holes for the license plate (not a big deal since we are not required to run a front plate here), prime paint install enjoy.

I have also been toying with the idea of installing a set of actual driving lights in the truck.  Not those cheap LED lights found at walmart, but actual white light, driving light, lights as they are supposed to be.

Pictures will be found here when this is done.

The introductions...

Hello reader! My name is Dale (but not Dale D. Mechanic) and I live with my girlfriend in a nice little house in an ok (usually) borough in Southeast Pennsylvania.  Please forgive my non-specifics on these matters, I do this out of habit.  I'm in my early 40s, am trying to quit smoking, lead a somewhat normal life...

I am a mechanic by trade, something that it could be said I entered later in life. After working in the green industry for almost 15 years, I realized that there was nothing new under the sun, or whatever weather I was stuck working in, usually for 12 hours a day, ten months or better out of the year.  I suppose I would still be working in that green industry if the company I had given ten years of my life to had not decided to outsource my position.  Such is life.

After a short time working for the company my position was outsourced to, I found myself working as a fleet mechanic again in the green industry, mostly tree care, then taking a job with a fleet in Philadelphia, then getting sacked so that they could hire a drug dependent loser that thought he could do the job for half the pay, and who incidentially no longer works there either. 

So these days I work for a small equipment repair shop.  Honestly, it took me some time to shed the fleet maintenance mentality of "just make it work" and adopt the "fix it proper and ship it out" code of ethics.

You probably noticed that the name of the blog is "The Dakota Files".  So I would like to introduce the "angry duck."

The "duck" is a 1996 Dodge Dakota Sport.  It sports a 2.5 liter inline four cylinder engine, five speed manual transmission, standard cab, short bed, Chrysler corporate 8.25 rear end with a 3.55 gear ratio.  It started life as a red truck but since it was part of a fleet they decided to paint it yellow.  It currently has 225,000 miles on it, but runs reliably.

Besides the non factory paint, about the only enhancements that have been done are an aftermarket cd player (that refuses to play cds) and a hurst "T" handle shift lever.  I have also painted the wheels a graphite color and clear coated them, had a set of new tires installed (pro tip: paint wheels AFTER tire installation).  Maintenance items that have been done are oil changes, repairing a burnt wire that while in two pieces refused to let the truck start, installing a new starter and replacing the battery terminals because the old ones were crap.  I also have replaced the battery.

This brings us to the list of maintenance items that I need to do, preferably before the inspection runs out. (Yes, we have yearly vehicle inspections, safety and emissions, that pack a hefty fine if you are caught driving without a valid one.)  They are:

1.) Full tune up (cap, rotor, wires, plugs)
2.) Find and fix reason the check engine light comes on intermittently.
3.) Repair the parking brake cable and anchor/pivot point.
4.) Replace the serpentine belt.
5.) Change transmission fluid. (probably has never been done)
6.) Change differential fluid (also has probably never been done)

And some modifications, which are:
1.) Replace right inner door panel to match left inner door panel.
2.) Replace right mirror.
3.) Repaint rear bumper (and maybe get rid of plastic step cover?)
4.) Repair rust on rocker panels under door.
5.) Install bucket seats.
6.) Install radio that plays Cds.
7.) Clean up interior, especially the carpet.
8.) Find where the water leak is coming into the cabin.
