I recently had my Celica with a 5sfe taken in to get a new radiator. problem being now is i think there is air traped inside. Tried Numerous times to bleed it.. what happens is when i take the car for a long drive and shut it down it dumps about a litter of coolant out the expansion tank and it also dose sometimes when the car is running.. Temp is normal according to the gauge and the car runs fine otherwise. I've taken it back to the mechanics and they failed to fix the problem. What's worse is i had plans to go on holidays and drive this car there. witch is less than a week away!
My bleeding procedure is the following so correct me if Im wrong. Turn the heater to full hot. (fans off). Start the car with the rad cap off. using a small funnel wedged in there i top off the radiator. I then rev the car as it seems to help purge the air out. Wait for the bubbles to stop and shut the car off and refit the rad cap. please help. |

I hate using my wife's car!!! 8( I'll try to check this today and see what happens!! As I said, Toyota designed the radiator fan to run unless the temperature switch turns it off. If the temperature fan switch/sensor fails, the fan will run constantly. If you unplug the fan switch/sensor, the fan will run constantly. You can test this with a pot of water, a thermometer and a multimeter. Below 83C, there should be continuity between the terminal and the switch. Above 93C, there should be no continuity. Or as noted by other posters, turn the car on and let it idle. If the fan switch/sensor is working, the fan will only turn on once the engine reaches normal operating temperature, and then it should cycle on and off. I'd still guess at the radiator cap being a problem. If the cap does not hold the correct pressure the coolant will boil, creating bubbles. Toyota parts are the best choice, though some aftermarket manufacturers such as Stant produce reasonable quality. The Toyota part number for a sixth-gen Celica radiator cap is 1640172090.
