loosing coolant without leaking under the car, so it is burning coolant, mine is staying on and so is engine light and it is also a 99 grand am gt and just happened today :( now we to put upper gaskets in.
Signs of a blown head gasket are: White smoke that has a sweet smell coming from the exhaust. Loosing coolant with no apparent leak. Coolant mixed with the oil, which will look milky. Air bubbles in the radiator when the engine is started cold with the radiator cap removed. A cooling system bleed down test will verify a blown gasket or leak. Finally a compression test will verify a blown gasket or cracked head.
With a blown head gasket the engine will still run, poorly with issues, but run. A blown engine will not continue to run from that moment on.
Intake manifold gasket
Those are signs of a blown head gasket or a cracked cylinder head.
could be the fan sensor...fan should kick on at about 220- 225 degrees {about 3/4 of the way up the gauge....more likely it is a blown head gasket, or blown lower intake gasket, lower intake, look for signs of antifreeze around the bottom of the intake, head gaskets, look for white smoke out of tailpipe
White smoke from the exhaust is the most common sign. A compression test will tell you allot.
This sounds like a classic case of a blown head gasket. You can look for signs of leaks where the head meets the block, but the best test is a compression test. Replacing the head gasket is a fairly big job. If you decide to do it yourself, you'll want a Haynes or Chilton manual to guide you through the job. FriPilot
General signs of a blown head gasket: Oil mixing with water water mixing with oil Run engine to normal operating temperature Remove dipstick and let a drop of fluid fall on hot part of engine - oil will smoke water will "sizzle" White smoke from tail pipe
Yes, that is possible. But, know that if you have a blown head gasket you will do serious engine damage if you continue to drive the vehicle. You need to have this looked at by a trusted mechanic. Do not continue to drive the vehicle.
Usually a blown head gasket will allow cooling water to enter the affected cylinder. This can be detected by observing the spark plugs for water on the electrode, or a clean washed appearance. A gasket blown between cylinders, may show no sign of water, but depending on size of the engine, may be hard, or impossible to start. The quickest, and most sure way to find out, is a compression reading of all cylinders.
if it is lowering oil and water both and is not leaking it may have a blown head gasket and it is going out the tailpipe
No, head gasket work with the cooling, however it has been known to mix with the oil and make it milky, i guesss if to much mixed in the oil section then yes cause oil seal, valve cover gasket, all could fail at that point and leak but the oil you see should be white'sh brown. here are the signs of a blown head gasket back up of cooling in overflow, milky oil on dip stick, and the number one pick of signs is wet spot on block right around the head.
