#17045 of 18329 Re: 2002 trailblazer overheating problem [havasusteve]
Jul 24, 2005 (7:34 am)
when we got the truck back from the body shop it started show temps in the 210 to 240 and more near the 240 side.
Was the radiator damaged? Did they replace it? I guess it was an independant body shop that did the collision repairs since you say you later took it to "chevy". If the body shop replaced it, did they use the correct OEM part?
With the new part in and it does the same thing, why did they replace a part when in their own words was 235 was ok?
Maybe trying to make a buck or two?
Yes they do get paid to do the work, but I would think since you told them it didn't go over 210° before, they went ahead and performed the repair based on that complaint. When I had mine in for the last of several warranty attempts to fix the A/C back in Jan just as my warranty ran out, (a few months before they released the "real" fix for my problem that they now want $600 to fix), the service writer told me the number one failure on Trailblazers is the fan clutch, so they probably honestly expected it to fix your problem if all else checked out OK.

I was wondering if you believe someone could change that actuator themselves? If so do you know where to locate this particular one at. If not how much did it cost at the dealership. Thanks

What is the recommendation as far as mileage for the plug change? Has anyone attempted this yet? I assume they are are on the exhaust side of the engine. I looked [quickly] but I didn't see any wires.

Remove the air intake box on top of the engine and you will see the tops of 6 individual coils, one for each plug. Remove one bolt per coil, pull coil up and out, and there's the plug recessed down in a hole in the valve cover. Front one is a little more difficult to get out because of a wiring harness that's in the way, but unclipping-loosening the harness and moving a little bit will gain enough room to get the front #1 coil out. Plugs are good to 100,000 miles by the way as per your Owner's manual. If there's no misfire and no Service Engine light coming on, old plugs are fine unless you are pushing high miles or just want to replace as preventive maintenance.

#17051 of 18329 2002 Bravada Turning Noise
Jul 25, 2005 (10:25 am)
I have began to hear a noise that sounds a sort of like a CV joint clicking in the front of my 02 Bravada. It only has 33k. I say it sort of sounds like a CV joint because my past experience is that CV joints will click throughout the entire turn that you are making and this noise only happens periodically. Does anyone know of what this may be?

Definitely let us know if the new clutch works. I was advised to "just go ahead and pay" the $600+ and let the dealer repair mine, and then try to get reimbursed by GM, maybe they would cover it, (maybe not) depending whether there is some secret warranty policy the dealer isn't aware of. VERY FRUSTRATING to say the least, to have had this problem addressed several times while it was in warranty with no results, THEN after almost 4 summers trying this and that in various attempts to work around the real problem, they supposedly finally come up with a valid fix well after most '02s are out of warranty.
Anyone inclined to do so can search this forum and find several messages I posted in the past three years while I was still in warranty. I suspected all along from my observations that high pressure cutout was happening because of high temperatures and not enough air moving through the condenser, causing the A/C compressor to shut off and AC to not cool.

Not to throw gas in the fire, but check this link out.
The issue states on page three that "at idle it can take up to 2 minutes for the system to engage." If you notice, this issue came out July 2002. So GM knew about this from day one.
What genius thought that waiting two minutes for A/C would be a good thing in summer heat? Like my Dad used to always say ... "If it ain't broke, don't fix it." My Prizm takes less than 15 seconds to kick out cold air. 2 minutes to 15 seconds. Hmmmm ...
I am trying to follow this discusion, but I am a little confused. The fan clutch will be replaced free of charge under warranty, or do I have to pay for it if I want the new and improved fan clutch?

I am sure the reason I was told while it was still in warranty that they just work that way and there was nothing else they could do to make it work like it should, is because of that two minute delay of the fan clutch engaging. "They all do that."
As I read it, all new fan clutches after June or July are the new design clutches that have more minimum engagemment (the new ones don't almost stall or freewheel to the point you can see the individual fan blades turning while it's idling, like the original design) and also have faster response to PCM commands. If you are still in warranty the new design is what you should get.
One thing the bulletin does say that may concern some... "The new EV fan clutch has an increased minimum operating fan speed and an improved response time. Additional engine cooling fan noise can be expected with the updated PCM software calibrations."
So it's a trade off - more fan noise for A/C that works. Or, a quiet fan with A/C that cuts out when it's hot. Take your choice.
Or as Lee Iacocca says... "If you can find a better car, BUY IT". After 38 years of buying GM, I may take him up on that advice next time.
