2002 grand am 3.4

My son's car just died on him on the way to work. He said it lost all power and started to get hot. He pulled over and found a blown coolant hose going to the heater core. We replaced the hose and tried to start the car but it won't. It turns over but will not start and I noticed when he cranks it it will puke coolant out of the resevoir. This makes me think a head gasket but it should start so I am also thinking since these 3.4 liter engines are notorious for bad intake gaskets that this might be the case. What do you guys think? If it is the intake we can fix it but if it is blown head gaskets I'm not sure it is worth fixing.

If it's not cranking then it might've ingested coolant, effectively hydrolocking it.

It cranks over just fine but will not start. That is why I am leaning toward the intake gasket

if your pushing out coolant while cranking motor over you have a headgasket/cracked head issue. It will be compression from the cylinder pushing the coolant out of resivoir. If you had a bad intake manifold gasket chances are it would hardly idle as it would be a lean condition with unregisterd air entering the motor with no way of measuring it so it would have to be quite a dramatic intake leak to cause a no start. Does the vehicle seem to turn over faster? Yes = no compression.

also if you were so sure it was an intake manifold gaskte leak you could spray brake clean and or any flamable spray/propane around intake and the idle would change and or start beiong you are adding an extra fuel to burn

I will look at it again. It only piled water the first time we turned it over. I'll try the carb cleaner and see if it will start

Being a pontiac... my money is on headgasket.
