Having problems with your 2002 Chevrolet Malibu ?

My 2002 Chevy Malibu is overheating. I found that

\015 My 2002 Chevy Malibu is overheating. I found that the water pump was leaking and replaced it. It still overheats so I replaced the thermostat and it still overheats. It runs hot at slow speeds but doesn't overheat. As soon as I get on the highway the heat gauge just keeps rising till it overheats. Is there anything else I should look for?\015 Posted / edited by AnonymousUser on : 19-02-2018

Answers :

If your car is equipped with a 3.1 or a 3.4 litre V6 and you have preformed all of the above listed work then I would have to say its the intake manifold gaskets. They commonly blow on these motors. Just a design flaw, nothing but replacing them when they leak can fix this. Also run a coolant pressure test on the system to check for minor things like a leak that you cant see from visual inspection. Hope this helps.
I would have the rad checked. Also check for blockage, this can be done with a good flush. If the rad looks good, and everything else looks good. might just be the fins on the rad bend in and prevent air from going thru. Check that also.
