2000 Toyota Camry is having engine overheating issues - what is causing them?
Mechanics can't reproduce the issue, they say the car is fine, I'm not so sure. 2000 Toyota Camry 4 cylinder 135,000 miles. Timing belt replaced at 85,000 miles.
There are 2 things about this car that concern me.
1. When I start the car in the morning, there is a rattling sound that comes from the engine area. It goes away after about 3-5 minutes of the engine running. The timing belt is fine. So what is causing this sound? Is it possibly the reason for the overheating described below?
2. Engine temperature needle slowly starts rising when idling after driving at highway speeds for 2-3 hours. The needle comes down a little if I turn the heater on. Problem is fixed when driving at highway speeds. Turning car off and on doesn't fix the issue.
This also happens when climbing a steep hill for more than a minute at lower speeds. I think the electric fans on the radiator are not turning on when they're supposed to. But I never had a radiator flush and some people say that may be the issue. Other fluids, like coolant, are full.
The car is great for driving around town. I have lately been renting cars for lengthier drives. I would rather try to figure out the issue before finding myself in an emergency situation.
