My S14 runs cold....

[Bobby_Wu]

This is my first post....I just bought a 95 S14 a few weeks ago...everything seems fine on the car except the car doesn't heat up....the temp gauge stays close to the cold end...even if the car has been runing for awhile...there is no hot air coming out of the vents as well when i turn on the heat...could it be a problem with my temp or O2 sensor???please help..it's winter here...thanks..

Hmmm...well when does it start to get warm? How long does it take? My S13 takes forever and a day to get warm. I've always noticed that the ka is a cold running engine, atleast mine is.

i had the same problem with my s13. When i took the thermostat out, surprisingly, it wasn't open. I figured since i was running cold it was stuck open. I dismissed it and went to Autozone and bought a new thermostat and gasket, replaced it, and now my engine runs at normal temp within a couple minutes at highway speeds : )

Pull your thermostat and boil it. It should open at 170 degrees Fahrenheit, and close at 165. It sounds like your thermostat is not closing.

(Those are the KA24E numbers, someone with a DE FSM should chime in if they're incorrect for the newer engine.)

Thanks for all the information.K-Car Loser (j/k): my radiator fan comes on as soon as the engine is started up as well..my brother told me the fan shouldn't turn on until a certain tempurature...could that attibute to my heat problem?...i'll check the termostat as you suggested...Thanks for the help Lost_To_A_K-Car...
