Tip & How-To about Toyota Corolla
If the Engine runs hot or overheats: Check the coolant level in the radiator when the engine is cold. Check the radiator hoses and drain **** for leaks. Check the radiator, radiator cap, coolant reservoir, heater hoses and all hose connections for leaks. The radiator should also be inspected to ensure it’s free and clear of leaves, debris, etc. Remove the radiator cap when the engine is cold; run the engine for 5-10 minutes with the radiator cap removed to release air bubbles from the cooling system (this procedure may need to be repeated). With the engine off and the coolant still warm, touch the upper and lower radiator hoses. They should both be warm. If one is cold, the thermostat could be stuck in the closed position, or, the thermostat may have been installed backwards. If the problem persists, visit yourToyota Dealer Service Department for diagnosis and repair. DO NOT DRIVE THE VEHICLE if the engine overheats.
To repair: 1. Remove the cover on the right side of the under-engine. Drain the engine coolantinto a sealable container.
2. Take out the fan and the V-belt on the generator, then remove the generator assembly. Remove the two nuts that hold the water inlet in place and then pull the water inlet.
3. Lift out the thermostat and remove the gasket. Clean the gasket mating surfaces thoroughly of dirt and old gasket material.
4. Put a new gasket on the thermostat, then install the thermostat so that the jiggle valve is on top. Make sure the thermostat is set within 10 degrees to either side of the prescribed position.
5. Connect the water inlet and set the two nuts in place. Tighten the nuts to 8 foot pounds.
6. Set the generator assembly in place. Refill the engine with coolant. Start the engine and check for leaks. Replace the right side cover under the engine. Your done!!!!! good luck and email me for questions - Bray2thaden@yahoo.com
