Another case of Overheating Problem - Toyota Yaris Forums

Slacky · 01-21-2014, 07:55 PM

Hi All:

Yesterday it started with the temperature icon blinking red on the dashboard and went away. Today I checked and found pink fluid around the pulleys, belt and in the hood. Tried to recreate the issue and found some small coolant leaks. I noticed that if I turn on the AC I will speed up the issue.

Details:

- Fan runs normally.
- Refilled the radiator with green coolant without flushing to trace the
circulation. Leakage continue to be pink from parts attached and found
another small leakage in tube that goes from the radiator to the
thermostat.

Should I replace the thermostat and all the tubes and pipes that are leaking????

Your waterpump is bad, hence the coolant on the inside of the waterpump pulley. The hoses with the pink on them are A/C refrigerant hoses.

I agree, it is the waterpump. Replace ASAP.

x3 seems like your water pump has KAPUUT. I would replace asap and don't mix green coolant in your system or it'll contaminate the long life pink coolant from Toyota and cause more problems in the near future.

I just received the water pump (Aisin), thermostat (Original) and new 50/50 coolant.
