Car overheats at idle, ok when at speed

Temp usually goes to center, but when waiting at idle (drive thru lanes, stop lights etc) temp creeps up and will overheat within 5 to 10 minutes.

You will need to Change your Thermostat. A bad Thermostat will cause the Overheat Problem as Stated above. Also, Check you Coolant Level, and see if the Water Pump is Pumping Water through the Radiator. Please Rate my Response, I need all the Help that I can Get! Thanks!

What year is your car? If the temperature gauge gets between the 3/4 mark and the red then the fan turns on while the car is sitting still, then that is normal operation of the car.

If the fan never turns on then you need a new engine coolant temperature sensor. Depending on the year of your car you may have one (1991-1995) or two (1996-2002). The one that sends information to the PCM is the two wire sensor on the drivers side of the cylinder head.

After highway driving for 2 hours and stopping for gas the car would initially start and then stall, it would run again until the car cooled for 30 minutes.


Sounds like your coolant level might be low. At highway speed you probably have enough coolant and with the air passing thru the radiator keeps the temp down, but at idle not so much. Or depending whether you have a belt drive or electric fan. Belt driven, could need a new belt.

Auto coolant hot temp light comes on and temp gauge goes up more when idling at a light


If temp gauge is going into the red on a 3.4 engine it must be shut down or head damage can happen within minutes. I have a Monte Carlo that was overheating. I changed everything, thermostat, water pump, belt tensioner, radiator, all with no result. It would start out okay on a cold start but then I would come to a red light and the temp would creep up. Higher and higher until it neared the red zone. The heat would run cold. Most of the time, as soon as it was about to touch the red it would start to drop, the heat would blow hot again and all seemed okay but not for long. This would get worse and worse until the red hot light came on and I found myself on the side of the thruway. This problem is a blown head gasket. I had no other obvious signs, no white smoke from the exhaust, no oil in the antifreeze. I even changed the intake gaskets. Head gasket issues are common on the 3.4 liter engines.

Check coolant level, and possibly replace thermostat. When a thermostat gets stuck in the closed position, coolant does not circulate thru motor. Gauge stays midrange when driving, because motor is being cooled by air and or the fan. If car seems to operate completely normal, then the gauge is faulty.

1999 Toyota Camry Idle Problems on Hot days


Clean the IAC. Disconnect throttle body air hose and you will see a hole on the bottom of the throttle body just before the butterfly valve. Spray throttle body cleaner down the IAC hole and then let it soak about 1/2 hour. Reconnect hose and run engine about a minute and then repeat this process 2 or more times. Toyota engines from 1997-2005 commonly have the IAC get cruded up with carbon as early as 35,000 miles. This is a sImple and cheap repair that many repair shops don't want you to know.
