That is normal. The coolant will get up to 180F within just a couple of minutes of running under load.

Define overheating - what are you experiencing? Could be a bad rad cap, could be a faulty coolant temp sensor, could be a blown head gasket etc etc

Are you positive you put enough coolant in the car? You might have an airlock. I've done many coolant changes and the Yaris purges air pretty easily if you have enough coolant in the system. If you have a smart phone you can pick up Torque Pro app and a cheap OBD2 bluetooth adapter (everything for under $20.00) and monitor coolant temps. That's what I use so as I approach ~180 F, I start feeling the upper rad hose for heat to see that the thermostat is opening.

And the electric fan is running, it should run when the AC is on.
And on mine 2013 the rpm on the fan increases when the coolant get hot. So it could be the thermoswitch on the coolant.

Pull the rad cap while cold, start the engine and let it heat up. If start seeing bubbles you have a head gasket leak. Had that happen on an old CRX race car I used to crew for.

If everything started when you ran the car with low coolant level I think air could be the problem.
Double check all your work and flush the whole system as instructed in the water pump replacement guide. Properly fill and bleed the air out of the system, use toyota coolant. |
