Thank you for your help. Before my girlfriend had her accident we saw no variation in the temp. It always stayed at 210. Then when we gat the truck back from the body shop it started show temps in the 210 to 240 and more near the 240 side. We then took it to "chevy" and told them it was overheating. They called said it was the fan clutch (with extended warrenty) will only be 100 bucks.So we had them do that. On the way home the same problem occurred. Called them back and told them the problem had not changed. We have to bring it in monday again. They did make the comment that the mechanic drove it for 12 miles and it didnt overheat and that 235 wasnt that out of line. I didnt tell them how hot it was running but to check it. 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?

Well 235 may be ok pulling a 5000 lb trailer out of Death Valley! Ask the dealer to take a ride over the same route in another TB.
Since it was ok before the accident, what body/repair work was done.... and could those repairs have any connection to the problem?
I would suggest making a record of the condition(s) that produce those high temps.
You live in Lake Havasu? If so, it does get hot along the Colorado!

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?

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?
