Tune Up Coming.. Help with Checklist - 7/2/2008 7:30:27 PM    Cowboy6622 Posts: 2928 Joined: 6/6/2007 Status: offline Alright guys.. I''m abotu to do a big tune up on my car... heres what I think i wnat to do... 90,000 miles, 5 years old. New wires, new plugs (need help on which ones to get) New Coils (leaning towards GM stock... hear some good and bad about all aftermarkets) New Fuel Filter New Cabin Air Filter I tried to post on this awhile back when the forum was screwy... can anybody else give me some help? _____________________________ "Ye thou I drive thru the valley and the shadow of rice, I will fear no turbo, for thy 3800 V6 art wit me, thy horsepower and thy torque, thou comfort me."

Clean up the terminals a little with a scotch brite pad and some elctrical grease and save yourself 150.00 As for plugs...im not too sure what the n/a guys are running so maybe someone else could chime in....but the factory wires are more than enough for your application (unless your just looking to add some color to the engine compartment). Check your tranny fluid and if its not burnt, just a little dark i would recomend changing the fluid and filter. Drain the coolant and flush out the dexcool REALLY good. Try to get any old sludge build-up out. Might as well replace your T-Stat with a 180 while your at it. Get some MAF cleaner and spray down the sensor (or a little bit of brake clean...same stuff). Other than that, you got the main idea. Dont forget to check the PCV... (in reply to Cowboy6622) Post #: 2

Measure the resistance between the posts on each individual coil and simply make sure they arent too out of whack from each other. If you have one that is way off, than you know which one is bad and would need replacing. good luck! (in reply to KidSpace) Post #: 5

Welcome back Space!!! I started a personal boycott on here: no posting until Space returned.  Glad to see you back!! (in reply to Cowboy6622) Post #: 7

So here''s the list: Plugs Wires PCV Valve T-Stat Tranny service Fuel Filter Cabin Air Filter Looks like fun!! :) I don''t know what your wanting to do with the car, but really I don''t quite agree with a 180* tstat...unless you''re going to upgrade your car''s performance and race it, I don''t see a point. I could be wrong though. I was always told that it is bad for a motor to run at a temp less than what the recommend operating temp...but I know a lot of guys do it. I guess I''m asking what the benefit is over a stock temp tstat and if it is dangerous to run your car under temp. lol. Castrol is a great oil...both synthetic and non synthetics. Oh and on the Series II 3800''s the ignition module is connected to the coils, so if you are missing I would take that in to an Auto Zone first and have it checked first. Coils don''t usually go bad. I used a scotch brite pad and some electrical grease on my coil packs and haven''t had a problem at all. bfurches said it right, LET THAT DEX COOL GO! :o) lol. Let us know how it goes...I know I had a difficult time with the rear plugs, but I didn''t have a good place to work on the car and get under it and what not. lol. _____________________________ (in reply to rchurch) Post #: 8

BTW, my experience has shown Castrol as being some of the cheapest crap you can put in your car. _____________________________ "Ye thou I drive thru the valley and the shadow of rice, I will fear no turbo, for thy 3800 V6 art wit me, thy horsepower and thy torque, thou comfort me."

RE: Tune Up Coming.. Help with Checklist - 7/4/2008 9:23:29 AM    bfurches   Posts: 115 Joined: 10/26/2007 Status: offline on the 4t65 trans...DO NOT FLUSH! I cant stress this enough. Simply drain the fluid and pop in a new filter, do not use any type of machine or bring it to any shop to have them flush the trans. Upon inspection of the tras stick, if you find there to be excess clutch material (silverish gray material), do not bother draining the trans. The clutch material in the fluid is what keeps the tranny kicking, aspecially if you are experiencing any minor slips. Draining the fluid would only dramatize these effects. So plain and simple, if its a little dark, drain and refill. If there is any material on the stick, or really burnt fluid, leave it alone. As for t-stats, there is no harm in going down a range of roughly 20*. On the l36/ l67 motors, all of the timing maps are relevant to coolant temperature vs. IAT. When coolant temperature is lower (i.e. colder t-stat), your vehicle will run more agressive timing. For instance...have you ever gone out to your car after it sat for a long time, and for the first few minutes it felt like it was running a lot quicker until it begins to warm up? This is the vehicle advancing the timing in relation to what the sensors are feeding it. Naturally, a cooler running car will see more timing, hence more performance. You may sacrafice a few MPG, but I doubt it would even be noticeable. Running a car at 180 vs 200 will NOT hurt anything. People have even run as low as 160 in the l67 community through the summer flawlessly. (in reply to Cowboy6622) Post #: 10
