How do you fill a radiator on a Toyota Celica?
If there's no cap, you have to use the reservior & let radiator draw it in.
If the Toyota Celica VVTI is not blowing hot air through the heater, but the engine is overheating, there could be a problem with the radiator being plugged up. Sediment sometimes builds up in the radiator that can clog thermostats. Another problem might be the thermostat sticking or the water pump is leaking.
