Question about Chevrolet Malibu

1 Answer

After having the usual overheating problem with my Malibu (the intake gasket was warped from Dextron II rad fluid) a week later the overheat continued but would suddenly dissipate while driving. I'd attempt to alleviate the high temp by turning on the heat and putting the blower on the max setting only to find that I'd only get cool air. I am wondering is this a air exchange problem or something different with the radiator or a control module.

    All hoses are hot and while running I opened the bleeder valve enough that it spit some fluid but it is still overheating. Fans work, everything else appears fine and when I open the reservoir, the fluid isn't bubbling but sitting stagnant. I was thinking radioator next.

Suzuki swift 2005 1,3 petrol overheated .coolant fluid was boiling but didn't seem to leak .started the car again drove a couple of miles and the same again.


check to see if the cooling fans at the rad are working. if so then change the thermostat and refill the system. if not then have the head gasket checked for cracking. make sure the coolant is circulating if its not it could be a plugged cooling system or even a water pump impeller problem.

Overheating, loss of coolant, reservoir not working


Sounds like to me your mechanic is on the right track by having the rad cap changed. If the coolant becomes low again in the near future and there is no visible fluid leak on outside of engine or on floor/ground then your problem is internal and possibly a head gasket.

I would certainly give attention to the radiator.
I am assuming that the engine overheated and the heads warped causing the head gaskets to "blow".

I would consider inveting in a new radiator.

l could suggest you to check your engine thermostat if is working. if it is found defective,replace. some say, yes, could be the head gasket. it causes also of overheating. but smoke you notice at the tail end, could be you have broken valve seal and eats up the oil. this another problem makes the engine's overheating. the 25 old old engine really need an overhaul.

My 2002 Chevy Malibu is overheating. I found that


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.

93 olds cutlas supreme overheating but there is no steam. Where is the fan temperature sensor located?


Usually near the thermostat.
By the way, remove the thermostat and drive around with the car. If it still overheats, might have some other problem, like you said, temp sensor, or some kind of electrical problem.

Overheating


What motor? If it is the V6, check for leaking intake gaskets.

Low coolant + little coolant going through the heater core ergo no heat inside vehicle.
