Can a clogged heater core cause my '96 toyota tercel to overheat within about 5 to 10 min of engine start running at idle?
Symptoms are vehicle overheats very quickly.
I believe that the radiator fan runs.
Windshield defroster was putting a film on inside of windshield.
I have not replaced the thermostat or radiator cap.
I assumed that the heater core was bad but the more i look into it it seems that there are quite a few
possibilities and maybe i don't have to replace the heater core.
