I already wrote something before about over heating for toyota cars but i may have to repeat myself again with easier and differnt literature this time round. This is for all toyota car novices to read.
Normally, your Toyota’s engine temperature shouldn’t climb to the red zone even if you push the car a bit harder in a hot summer day. If the temperature needle goes way off above the center position on the dial, you may have a problem with the cooling system.
Diagnosing the cooling system is fairly easy, especially on older Corolla models with simpler engines. So here are some tips on how to spot the problem:
- First of all, make sure there is enough coolant fluid in the system. To do so, look at the fluid level on the expansion tank, which should be somewhere between “Min” and “Max”. Also, you can check the level in the radiator if it has a visible cap at the top. Be aware though, don’t open that cap if the engine is hot because under-pressure steam might burst out and cause you severe injuries.
- If the water levels are OK, check if the thermostat works. The thermostat is like a valve that opens at a certain temperature to allow the coolant into the radiator to cool off. To see if it works, locate it, take it out and boil it to see if it opens.
- If there is no water in the system, replenish it and check for leaks. If you don’t have engine coolant and you’re in an emergency, use just some clean water, but don’t forget to flush the system and replenish it with 50-50 water and coolant (antifreeze).
- Also, don’t forget to check the water pump for leaks or incorrect functioning. If there are strange noises or squeaks coming from it, this can signal its wear and low efficiency.
- Another check you can perform is verifying if the electric radiator fan works. It should normally kick in when the engine gets hot. If not, check its fuse and replace it with a new one. If that’s not the issue, the electric motor might be toasted.
