2001 grand am fuel smell in coolant now won't crank


You have a blown head gasket. This is not a cheap repair, the intake and exhaust manifolds have to come off, the head has to be removed and check for warp. The block has to be checked and the gasket replaced

Over heate my 2002 grand Cherokee . It has 3 codes po 300 po 301 po 302 . Blown head gasket ?


You are probably right as all codes refer to misfire in cylinders.. have a compression test done to check for blown head gasket and cracked/warped head and have a cooling pressure test done also to show cracked head and other than head gasket.

How to tell if i have a blown head gasket on my 2004 pontiac grand prix


The only way to know for sure is to pull the heads and check the head gaskets.
Oil in the cooling system or coolant in the crankcase is usually a sign of a gasket failure.

What's the difference between a blown head gasket and a blown intake gasket?


The head gasket goes between the block and the head, and seals the combustion process, and cooling water, and (if oil is pumped obove the heads to valve components) oil pressure.

Intake gaskets seal between the intake manifold and the head, and seal against intake vacuum, and in many cases, coolant.

A badly blown head gasket will so destroy compression in the cylinder that you can hear uneven cranking as that cylinder comes up on compression, kind of a “whir, whir, WHIR, whir, whir, WHIR, whir” with the capitalized whir being the engine spinning much faster due to no compression holding the starter back.

You will never be able to hear a problem with an intake manifold gasket until the engine actually starts to fire and/or run.

Head gasket blown out and it will not start


You answered the second part of your question with the first part. Your car will not start because of the blown head gasket. You'll need to repair the head gasket and any other damage first. Often a blown head gasket is just a symptom of other problems and sometimes it's the cause of other problems.

I just replaced the intake gaskets on my 2003 pontiac grand am , but when I went to fire it up it was still running like **** come to find out the head gasket on cylinder 3 is blown or the head is cracked....


theres an easier way to fix a blown gasket, its called seal-up you pour it in your radiator and it chemically welds it back together look it up on google most auto shops sell it or something similar, but replaceing the gasket is the best way

99 Grand Am was leaking coolant from the over flow?


could be that it was hot or could be that you have a blown head gasket. If the engine got hot once it could have been enough to blow the head gasket. Does it blow it out after it warms up every time?
