if its not working.
I set the thermostat for 70 degrees.
If the thermostat is broken in the closed position the engine would overheat rapidly. If it was broken in the open position the engine cooling system would not reach normal operating temperature and the heater would produce only warm air. Take the thermostat out and put it in a pan of water on the stove. When the water gets to around 200 deg F, the thermostat should open. If it doesn't it needs replaced. Observe carefully that you have not installed the thermostat upsidedown.
you will know your thermostat is broken on your 94 celica because the engine temp will never raise and the engine fan will run continuously. I have a 92 and my thermostat is at the bottom of the engine, hard to get to because it's close to the left quarterpannel. I'd get a chilton's or some other repair manual, it will help you out tremendously. -J
