Question about 2003 Saturn VUE

1 Answer

What causes a engine not to heat through out?

I have a 2003 saturn vue. I had to replace the engine. After replacing the engine, the car would not heat the inside. The mechanics change the thermostat. He said the engine temperature was approximately 176 degrees now it is over 230 degrees. He is claiming now that only part of the engine is heating. After spending over $350 I still have a problem. He said that it could be the water pump. Is there anything else I should consider before replacing the water pump?

    yes, while the engine is warm and you have turned on the heater, check the heater hoses under the hood, are both of them hot? does it produce heat only when the engine is reved up?

Make sure theres no air in system..Your heater core could be plugged..Your fans may not be working,Or it very possibly could be the water pump.Or the radiator could be plugged not letting it circulate water..Could also have thermostat in backwards causing it not to flow also..Hope these help you find your problem and good luck Have a Great Day...

Where can I get a wiring diagram for a 2003 saturn vue? After turning the air off, and the knob setting to zero, then turning the car off, I can hear the fan running for some time (like 10 minutes)...


That is the normal if your taking about the radiator ran, as long as the engine is hot, the radiator fan will run till the engine cools down enough for the temperature sensor to turn off the radiator fans. Your Saturn is 2003 and if you have not serviced the cooling system it may be time. The orange antifreeze has a life of 5 years or 150,000 miles and the green antifreeze has a life of 1 year or 30,000 miles. If the antifreeze has not been replaced, it may be a good thing to have the system flushed out with Preston radiator flush and then the antifreeze replaced with a 50/50 mix (water/antifreeze). If your not sure how to mix the antifreeze, you can buy them 50/50 premixed, With then new coolant, your engine can transfer the heat much better and will cool down faster. Note, too much water will boil over and too much antifreeze will gel up causing over heating. Good luck and hope this helps, keep me posted, be glad to answer any questions you may have.

2003 VUE-how do i locate/replace coolant temperature sensor


Its on the drivers side of the engine below the intake manifold. Why do you want to replace it? I have worked with the VUE since day one and I have yet to see a bad coolant temp sensor. If you are having trouble with the engine temperature or the amount of heat in the car a very common cause is the thermostat sticking open and not alowing the engine to reach operating temperature. The most common telltale to this condition is usually the service engine soon light is on with a p0128 code stored in the PCM.
