Q: car stalling,and running hot and idling up high. 1996 Toyota Camry

Hello. If your car is running hot, this needs to be addressed first. If there are other problems with your car, you can’t diagnose them without being able to run the motor withoutoverheating. If it is shutting off from running hot, you are risking and may already have damaged the head gasket. Your 2.2L Camry motor is particularly prone to this when they overheat.

With the car cold, make sure the cooling system in full. Look for any leaks. If the cooling system is full without any leaks. The next thing to suspect is the thermostat. Begin warming the car, watch the temperature gauge, and keep feeling the upper radiator hose. When it gets hot, the thermostat has opened. If the gauge shows your car is overheating, but the upper radiator hose isn’t hot, then you should begin by replacing the thermostat. Keep in mind you need to do this when the motor has cooled off enough so as to not burn you.

在加热汽车的过程中，如果您可以访问设备，我将检查头部垫圈故障。这样做的最佳工具是可以检测HC（碳氢化合物）的气体分析仪。大多数人无法使用这样的机器。因此，下一个最佳工具是所谓的块测试仪。您可以在大多数汽车零件商店购买此产品。确保仔细遵守说明。

如果在加热汽车的过程中，您找不到头部垫圈故障，并且发现需要恒温器，然后更换统计数据。如果恒温器和头部垫圈很好，那么接下来要怀疑的是散热器和水泵。卸下加热器软管，然后启动汽车以测试水泵。您应该看到随着电动机的运行，水从断开的软管中流出。如果没有，请怀疑水泵.

Testing the radiator requires a thermostat that opens and a test drive around the block. You need to get air blowing through the radiator to perform this test accurately. After your trip around the block, stop, turn the motor off and feel with your hand along the radiator. It should be consistently hot at the top and progressively cooler as you move your hand to the bottom. If you feel any cold spots, you have aclogged radiator应该更换。

Once the cooling system is working properly, I suspect the reason for the stalling is your motor getting too hot. If it still stalling once you get the cooling system in order, you now have more to diagnose.
