#340 of 344 Suzuki Vitara 2002 not heating, rad guage red
Nov 11, 2011 (10:51 pm)
I have a 2002 Suzuki Vitara and I can have the heat on full, and all I get is luke warm air. Its been this way forever. Have been noticing the temperature going up. And now It almost goes into the red at stoplights. Recently changed the thermometer, water pump and today the rad. Well, It did not make one bit of difference. Am waiting for appt. to check rad pressure, or something to tell me if it is the head gaskets.
Anyone have similar problems?
Thanx for your time

Have you replaced the radiator cap? If this fails to hold at specified pressure it could overheat. If you are losing coolant and it is not visibly leaking anywhere it certainly could be a bad head gasket. With no coolant loss, it could be a faulty temp guage (unlikely) or a faulty fan clutch which looks like it's working but actually isn't pulling enough air through the rad to cool it. As far as cabin heat, have you ever changed the cabin air filters? There are 2 behind the glove box. Is the temp low or the volume of air flow low? If it is the volume, it most likely is clogged cabin filters. If the temp is low it may be a faulty control valve not allowing enough hot coolant into the heater core. Good luck!
