Assalam o Alykum.
From last few days i am having a problem with my car's temperature gauge..when car is stopped the temp gauge automatically goes up to the red spot. And when car is in 5th gear it slightly goes up..but as i come in lower gear the gauge comes back in the middle. i went to many electricians and they checked all the wiring, thermostat .water plug all were working correctly..but my problem remains the same..i need suggestions from u guys.. i have 1986 corolla with 4e engine.
