Chevrolet Malibu Problems

Intake Manifold Gasket May Leak Coolant or Engine Oil on Chevrolet Malibu

Problem Description and Possible Solution

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

I noticed my 2002 Malibu LS was over heating and I could smell burning antifreeze. Took it to a mechanic was told the intake gasket manifold was leaking. Paid $700 for the car to be "fixed" not even a week later and its still running hot. I can still smell burning antifreeze and my car is blowing out cool air
NO HEAT! This is ridiculous.
Always oily substance in my coolant reservoir, although I never see any discoloration in the oil itself...
I was losing coolant and wasn't sure what was going on, my daughters father is a mechanic, and took my car he told me that the intake manifold gasket was leaking and that it was very common on these cars, im not surprised I mean im always having some sort of problem, anyway I bought the parts he replaced the gaskets, but... im still having some problem my car is now overheating badly im not losing coolant so idk now im so tired of dealing with this not to mention broke idk what to do anymore any ideas would be wonderful
Mechanic said intake manifold gasket leak and cracked manifold-$1500 10,000 miles later, leaking in the same place, behind power steering pump. I took pump loose and laid to the side-antifreeze leaking around two manifold bolts. These bolts come new with a coating on the threads to seal and keep them tight I guess, its not enough. I took out the two leaking bolts, cleaned them up on a wire wheel, coated them very well with sensor safe Hi-Temperature Silicone, put some in manifold holes also and tightened up, put rest back together and let sit 4 hours for silicone to dry and now have 150,000 miles on car with no leaks. An old mechanic told me 30 years ago to silicone your intake manifolds for trouble free future, no matter who luaghes at you for doing it. I think it could be the bolts causing the problem, not sure. It couldn't hurt to use gasket sealer when replacing, but of course your mechanic would lose business that way. Car won't start half the time-theft system or what? When it runs I love it-LOL
Intake manifold gasket needed to be replaced. Went to get oil changed and tech advised there was oil in anti freeze. Seems to be a common problem.
The repair cost me about $2000.00 at the local dealership. I had them change the water pump also since they had the engine dismantled. Now the car has a kicking problem when I stop for a light or driving very slow. Seems like the trans.
Coolant began leaking around 70K miles. Added stop leak to engine, which has been sufficient with little leaking since (mileage now at 90K).
Was slowly loosing coolant but didn't ever see any on drive under car or anywhere on engine. Took it to dealer and was told the water pump was leaking. Had dealer replace water pump but slow leak continued. Took it back to dealer and this time was told leak is going internal and head is bad and it will cost $2500 to fix in addition to the almost $1000 already paid to Baum Chevy for them to NOT fix the problem.
Anitfreeze Coolant burning out. Low coolant light coming on repeatedly. I was told that I would need to replace the headgasket-$1500-$2500 (which I did) & problem still continues?
Oil entered coolant overflow & engine repeatedly overheated. Head gasket replacement fixed this problem
Symptoms of blown head gasket, most prominent being exhaust from combustion chamber pushing coolant back into and out of the over flow tank, causing engine to over heat. have yet to fix the problem, Malibu has simply been un drivable. Hope to replace gaskets soon.
The engine always leaked coolant. After having the entire coolant system replaced twice the engine finally overheated. The car is not drivable. The coolant light did not come on or beep before it overheated. It's also had issues with the thermostat and sensors. The problem could not be fixed even after smaller repairs to the coolant system.
I'm on my 3rd replacement of this same part! I am told each time that it is a known problem and they have totally redesigned the part to rectify the problem...each time costing me over $650.
Intake manifold leaked coolant for the second time. The first time was at about 60000 miles and was serviced by the dealer.
Car keeps overheating. Took to shop was told nothing was wrong. paid $45 for check. Two days later car overheats again. Took it back now I'm told it needs a thermostat $170, water pump $230, resivior $120, radiator $360 and intake manifold gaskets $620. really??? how does something change that fast.
