My 1996 gmc jimmy began blowing cold air last winter. We had the radiator flushed and refilled with dexcool. The company told us the dexcool had turned to a sludge and damaged the thermostat. The thermostat was replaced as well. Six months later we have had to have the radiator flushed again because of overheating in the summer. Again the fluid had turned to sludge and we have to get the thermostat replaced again. It appears from what I have been reading that the entire system will have to be replaced soon because of these dexcool issues.

After replacing the water pump and thermostat at 117000 miles, the engine overheats when the A/C is used for long periods of time. Afraid to travel due to overheating. Bubbling from under the dash also. When not running a?c it runs ok. Fluids all well changed and maintained regularly.

1995 gmc jimmy sls 4 door 4wd vortec 4.3 l v6. We have had this thing for 7 years and nothing I have ever owned has taught me more about being a "shadetree" mechanic! The list is as follows, break booster replaced 2 times. Egr valve replaced 3 times. Front brakes replaced at least 12 times (they fail every 1500 to 1800 miles!) back hatch wont open. Both set of wipers, front and back do not work( safety issue!) engine overheats. Water pump replaced 2 times. Thermostat replaced 3 times. Lights flicker as if the altenator is going bad,(resulting in police asking me to check into this.) battery replaced 4 times (average life of new battery, 4 years!) transmission shifts very hard when engine is cool/ hot! Starting to see rust in trans, dipstick. Sometimes cant shift from 2 wd to 4 wd and when able, transfer case makes clicking sound. This is not a phony complaint! I need help with this as I never see a recall, warranty is out and I cant afford to take it in. I don't think I left any thing out, but im sure my wife will let me know. You can give my name to who ever when ever if it will help us fix this situation.

Tread seperation in phantom a/p tire that was manaufactured within time period of the federal safety agency action #pe02056. Substantial physical injury to 72 year old driver and total loss of vehicle. Rimkus consutling services expert garret mitchell made the following conclusions: 1.a defect in the left-rear tire on the chevrolet caused the tread to separate from the carcass. The nature of the failure is consistent with contamination or improper vulcanization of the tire components during manufacturing. 2. The sudden failure of the tire caused the driver to lose control of the vehicle and subsequently collide with a solid object. "there was a presence of polishing and bluing on the rubber carcass of the tire [which indicated] overheating of the tire. . . . If evidence of overheating is observed around the entire circumference of the tire, flexing of the tire due to overloading or under-inflation is indicated. In this case, however, the evidence of overheating is limited to one area of the tire, specifically the area where the tread began to separate from the carcass. This indicates localized overheating due to friction between adjacent tire components was taking place in this area. Furthermore, the remaining tread in this area is unevenly worn, indicating a discontinuity in the tire structure at this location. These observations indicate the components of the tire were not properly bonded together in the area where the tread separation began."

Reddish liquid leaking from under engine and engine appeared to be overheating, temperature needle going all the way up, then down, bad smell. Mechanic told me he has seen this problem with these vehicles before due to dex-cool used which gunks up the cooling system. Water pump had to be replaced due to the damage from this stuff. I was very disappointed in the response I received from the people from gmc who apparantly know about this problem and are doing nothing about for their customers.
