Have oil gunk in coolant reservoir, just started. Can hear hiss. Head gasket?

Run a compression test or...very carefully and on cold engine only: remove radiator cap, make sure coolant level is good, stand back and have someone hit the starter. If headgaskets are bad usually (not always) water will shoot out of the radiator. Sounds like this is your issue

I have a 2001 Pontiac Grand Am SE. In the last week my car has been revving when i start it. I have been turning the car off when i notice it revving and usually after three tries it stops revving. Now im...

It sounds like the engine has a bad vacuum leak, they are very problematic for a leaking intake gasket. This usually would be accompanied with coolant loss, but not always. Other causes are loose air plentum snorkel (if air filter recently replaced) or a leaking vacuum hose. It could also be a sign of a computer problem starting. It would be best to have a technician or parts retailer scan it for you to narrow the problem down. The clunk noise maybe unrelated or possibly engine noise(like an intake issue), check the oil and coolant levels first.

Go to any auto parts store, like Autozone or Kragen and ask them and they will give the right one. But be ready about the model, year, how many cylinder or size of the engine of your car. You can find all these on your Users manual or your registration. ok

Heat not working and service engine light on

Many times no heat is the result of low coolant which means there isn't enough to properly flow through the heat core. Check the coolant level. If you're running hot it could also be from low coolant. If the coolant level is normal you may very well have a stuck thermostat. If you do have low coolant the next step is to find the reason why it's low.

Check engine, ABS and Trac off lights come on

You should definitely get it looked up by your mechanic, because these lights are indicating low engine oil-- thus heating up, Your anti-skid for the brakes are also malfunctioned, maybe needs a top-up of brake fluid to say the least....sodeep
