== == Could possibly be a heater core leak. Coolant is getting blown up through the vents when you have the heater on. May need to do a heater core check and replace. if you have the a A C on it means that your A C freon its leaking, also if you run the AC on with one window open it will create smoke fron the humidity coming in to the car if it's white somke it's dangerous "cause it will put you to sleep while you drive and you will not feel it..
First check that you ave the correct level of water/antifreeze in your system. A Low level will cause this as well as lead to other more expensive damage. You might want to check your thermostat. and then also check the heater core to see if the hose is connected right and there are no leaks.
How do you remove the heater core on a 1997 Toyata Corolla?
Sounds like "heater core" is shot-any coolant leaks inside the car coming from under the dash?, Have check, replaced. Or could just be an air lock in coolant system, which is better easy fix.
fill up the system turn heater knob all the way to hot and run engine and keep your eyes on the temp gauge don`t let it overheat what you doing is getting the air out of the heater core when gauge started to clinb to much turn engine off and wait about 10 minutes be careful at this time put more coolant in reservoir (you can do this on a hot engine as that is water but antifreezze).run engine again the reason for doing this is because the heater core is mounted abovedthe engine
Drain the cooling system. Remove the water hoses from the heater core. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
their are 4 on top of the engine under drivers seat 4 more are located on the underside of the engine behind the oil sump
