Hi all
Last week my radiator cracked at the fill neck. I replaced it with another and that seems to have gone in just fine. It holds fluid without leaks. I also picked up a new thermostat but didn't install it yet. So... today I filled up the radiator with coolant and went for a test drive. It started to overheat again so I stopped, let it cool a bit and opened the cap to fill it and let the bubbles come out as it ran, heat was on. The reservoir was bubbling up too. I also unplugged the fan sensor so that they could run continuously just to be sure that they weren't part of the problem. Well, the fans work and seemed to slow the pace of the temp gauge rising, but I'm still overheating. Tomorrow I'll swap in a new thermostat. What else should I look for if that doesn't solve the problem? -------------------- |

Ok, so old thermostat was not opening. I replaced it with an oem one from toyota and tested it before installing. Thats all good now. I burped the system and even revved it up to heat up the engine. The fans never kicked on and i know they work. It didnt overheat but what makes those fans kick on?

There is a switch on the bottom left of the radiator (when you're facing the car) that kicks the fan on when your car gets to a certain temp it then shuts them off once the temp drops. An easy way to test if the switch is working is to unplug it with the engine running. If the fans turn on straight away the switch is working properly most of the time  |
