99 camry 2.2, I replaced radiator and thermostat, it still maxes out the heat gauge.

Asked by Oct 23, 2013 at 08:59 PM about the 1999 Toyota Camry LE

Question type: Maintenance & Repair

After replacing the radiator and the thermostat I got another new, more expensive,
thermostat and installed it. The fans work when the AC is turned on but not when the car
is running with the heat gauge as hot as it can read. Could it be the fan relays? I did test
the fans when I had them out for the radiator fix and they did work outside the vehicle.
Any advice is greatly appreciated.

There is a sensor in the radiator that measures the temp of the fluid. If you got a new radiator and just transferred your old sensor, that may be where your problem lies. Or the sensor is located near your thermostat housing. Check out this lhttp://www.youtube.com/watch? v=AThAioyjg60ink:

Take the wire of the sensor on rad or thermostats housing and ground it If the fan come on replace fan relay if not replace sensor H


If you get the fan working and the car still overheats.head Gskt kit From advanced auto ck the fumes from radiator changes blue Needs Gskt if the car has antifreeze and burns white smoke Also head Gskt.
