Re: Find and replace thermostat 2003 corolla--thank you !
Follow the lower radiator hose to the engine. Most Toyota's along this year model have the thermostat located in the engine, where the lower radiator hose connects to the engine. Changing the thermostat is pretty straight forward. Refilling is a little trickier. Search the top of the engine and find the bleeder screw for the cooling system. Open this bleeder screw, usually a 10mm, or 12mm socket will fit, and fill the cooling system with the recommended coolant. Pay attention to your mixing ratio as well.

Open the bonnet to access the engine compartment. Locate the radiator in the front of the engine compartment. There are two hoses that run off the radiator. The bottom hose runs to the water pump and is where the coolant is pushed into the radiator and moves up through the ridges to allow time to cool off. The top hose is the hose that runs to the thermostat housing. Follow the top radiator hose to where it is clamped to the motor and you will notice a housing that the hose is clamped to. The housing can be opened with a socket wrench. This housing contains the thermostat. You may need to remove the radiator hose to access it. Unscrew the hose clamp and pull the hose off the assembly. Once the housing is opened you can pull the thermostat out with your fingers.
follow the radiator hoses 2 the motor normerly were the top hose connects 2 the motor is the thermostat housing.but on some japanese cars the thermostat can be on the bottom hose make sure motor is cooled down as there is a lot of heat&pressure in the cooling system
The thermostat is located in the water inlet housing that is
connected to the lower radiator hose. The thermostat is equipped with a by-pass valve. If the engine tends
to overheat, removal of the thermostat would cause a decrease in cooling
TY for using Fixya (remember rated and comment this).
You can replace the radiator yourself, but why do you need to? The thermostat is on the engine. Follow the large hose that goes to the engine block....not the water pump. The thermostat is under that or sits on the top of the engine....looking for a pic for you!
I have to tell this: Your dealer screwed up. The P-0171 remedy was to clean the Mass Air Flow Sensor, NOT replace an O2 sensor. The P-0125 indicates that you have the insufficient coolant temp, which is a thermostat sticking open. This is why your idle is so high, the coolant is not up to operating temperature, 192 degrees F...Clean the MAF and replace the thermostat, and tell the dealer that he screwed up on the O2 sensor diagnosis/replacement. They put an O2 on for no reason. Better yet, have THEM clean the MAF and replace the thermostat. They owe you that much.
