I have a 1994 Toyota Camry that started overheating about a week after I bought it. It only does this at idle speeds. I had a pressure system check done, a new thermostat put in, and a new cooling fan installed. It stopped overheating for a couple of weeks, but then started doing it again.
We recently had our 2001 Toyota Avalon serviced by our local Toyota dealership for Engine sludge. 96,000 miles, and we had all necessary service and oil changes over the course of 7 years. This $3,000-$4,000 service was covered by Toyota due to a Class action suit back in 200-2001.
I usually get my oil changed at Jiffy Lube because they are convenient and I can’t crawl under my car and change my oil like I used to. I got it changed there a few months ago and shortly thereafter my car started to overheat and the heater stopped working. If I revved the engine really high it would cool off and if I was idling the engine would get really hot but the heater still blew cold air this was in February in Utah.
I saw your answer to someone below after searching for a good block sealer: “If they DO suspect a blown head gasket or cracked block you might want to try a can of KW Engine Block Seal additive you can buy at your local auto supply. Drain out the coolant, add the can of additive to your radiator and drive the car for about 500 miles, then drain out the water/additive and install the proper mix of coolant and water to the radiator.
