Toyota Thermostat Problems

As with all cars, the Toyota thermostat is the device that increases and decreases the amount of coolant circulating through the engine to ensure that the right operating temperature is maintained. Toyota thermostat problems can cause the engine to not get warm enough or overheat resulting in expensive damages. There are many factors, besides the Toyota thermostat, that could affect the engine temperature. The best way of diagnosing the problem is to ask an Expert for their opinion and guidance. Read below where Experts have answered questions regarding Toyota thermostat problems.

Where is the Toyota thermostat located on a 2000 Toyota Camry?

The thermostat is attached to the water pump. Locate the alternator on the upper left side of the engine, below that there will be a radiator hose going inside an aluminum or plastic housing. Remove the hose clamp and the thermostat is in housing that is held to the water pump by two 10mm nuts. Remove the two nuts and the thermostat, gasket and O ring. When replacing the thermostat, use only a Toyota thermostat which has a ‘jiggle valve’ built into it. This valve goes in at the 12 o’clock position to allow air to bleed by the thermostat until it has opened.

What will cause the temperature gauge on a 2003 Toyota Camry raises into the red zone when there are no other noticeable problems?

If the coolant level is good and the fan is running at the right speed the Toyota thermostat is defective and should be replaced immediately. The car should not be driven with a defective thermostat as the overheating could cause severe engine damage.

What can cause the engine on a 1995 SR5 pickup to continue to overheat even after the Toyota thermostat has been replaced?

The 1995 SR5 model has known issues regarding the cylinder head gaskets, and was recalled. First try replacing the thermostat with an OEM Toyota thermostat and see if the temperature maintains. If not, take the vehicle to a dealer to see if the cylinder head gasket is one of which was recalled and have it replaced with the newer one.

Why does the engine still get off after a new Toyota thermostat and radiator shroud have been put in a 1993 4runner?

The gaskets on the Toyota 4Runner were recalled due to overheating. Remove the newly installed thermostat and see if the overheating problem disappears. If so, install a factory Toyota thermostat with a jiggle valve that removes air pockets in the system. Additionally, ensure the fan is cycling on and off when the engine is hot and held steady at 2000 RPMs for 10 minutes.

Where is the Toyota thermostat located on a 1993 DX with a 16 valve engine?

The thermostat on this model is located just below the distributor. To remove it, drain the engine coolant and disconnect the Engine Coolant Temperature (ECT) switch connector. Next remove the 2 nuts and water inlet from the water inlet housing. The thermostat is now accessible and can be removed. This diagram should help to make the procedure clear.

Toyota thermostat problems can cause an engine to run to cold which can result in sludge formation in the oil, among other problems. Running too hot can cause engine seizure and other expensive damage. The diagnosis of engine temperature problems involves many variables, not just the Toyota thermostat. The best way to be sure that the right diagnosis has been done and the correct solution found is to get answers and opinions from Experts.
