Radiator problems of the 2001 Chevrolet Malibu

My car seemed to be riding rough and my radiator light came on. Today I went for an oil change and the mechanic said I had an "intake manifold gasket leak. " my oil is leaking into my coolant. He told me there was a recall from gm for dexcool. I can't seem to find any information on this but to have it fixed will be very costly.

I am having problems with my car overheating. I have brought my car to several different places and everyone tells me that this is common in Malibus,and something should be done about it. I have had my radiator replaced,my thermostat changed, my coolant system flushed. Now Chevrolet is saying it might be my water pump that's causing the problem. That will cost 586 and if that's not the problem they will check other things while im going to be the one taking the lost.

The vehicles heat gauge stopped working and low coolant light came on. Checked coolant level and discovered sludge in expansion chamber ( coolant recovery tank). Flushed system of sludge and trouble shot reason for coolant loss. Found intake manifold gasket leaking. Vehicle will require new intake manifold gasket set, thermostat, hoses, water pump and possibly radiator. Tried to flush system completely but found secondary plumbing such as heater core, radiator,coolant crossover and coolant bleed hosing gummed up with oily waxy type substance resembling gumballs (dex-cool?). I think gm should step up to the plate and take responsibility for the so called "wonder coolant". After all the sticker on the expansion chamber does say anything about changing every 5 years or 150000 miles.

A slow radiator leak was observed over a period of 2 months. I took it to a mechanic who diagnosed a faulty intake manifold gasket. He had mentioned that it is a very common problem in the Malibu, even though gm told me that it was not. The manifold gasket was replaced before any anti-freeze leaked into the engine.

The car made a horrible knocking noise shortly after I bought it brand new. 5 different dealers stated that the teflon from the rocker arms in the engine wore out and thatw as what was making the awful noise. Itwas cosmetic, so to fix it would cost a lot of money. Also, the intake manifold on the car has cracked causing the engine/radiator to leak anifreeze out the exaust. Gm needs to recall these cars because of all the problems. I can go on and on with my car. I have maintained it every 3,000 miles meticously and should not have this problem with a car that only has 60,000 miles.
