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.

My car temperature start to get a little bit more hot than usually, then after a month now it's draining all the coolant by a hose behind of the exhaust manifold on the firewall. No overhead problem,but it's terrible waste of coolant (money ). Anyone knows how to fix this problem! ???

I have a 2000 Oldsmobile Alero that leaks coolant. I was told that it was the Water Pump Hoses which I just replaced them so its not that. Then they said it could be the Harmonic Balancer, but I read that couldn't leak. Then they said I could be the Intake Gasket Thermostat. What is wrong with my car...... Source Tireman

Nothing seems different about the way the Alero runs, but when I took it to the dealer for unrelated repairs, they discovered that the intake manafold gasket was leaking oil. They said that it would not necessarily create a puddle, but rather would stream along the bottom of the car as it is driven. So far the coolant has not mixed. Watch out for wheel issues (control arm, brakes) with this model.
bought the car had 116,000 miles. intake gasket repaired at shop at 115,999. now has 20,000 miles out again.

I spent the money to fix the intake manafold gasket and it helped but during certain situations it would leak and on Ocasion it would all come out...My friend told me to replace the resivor cap and it worked! No coolant problems since.

steams from drivers side of the car only when you accelerate and not all the time. I was told the manifold gasket needs replaced and that it is not leaking into the motor yet

Intact manifold gasket failed

I was told it could the intake valve but there's no guarantee that would fix the problem. Or I could get a new/rebuilt engine.

well I have to refill my coolant every couple months or until my sensor light comes on. Right where the transmission fluid compartment is , is where you find coolent liquid on the outside not that much , pin hole maybe. I ran my car for the past couple days alot traveling due to a death in the family and my 3rd gear acted up as in I could not get her to shift into 3rd or take her any faster than 35 m/hr. Im really hoping the transmission isnt bad. Im really strapped for cash no credit and its my only vehicle...3rd owner and ever since I got her problems had results. Only a little over 88k miles
