Look for oil in the coolant, it will make a murky paint like floating substance in the coolant overflow and radiator. If this is the case you may have a leaking head gasket or intake gasket allowing the cooling system water and oil to mix. You may also notice a bluish white smoke from the exhaust when accelerating if the headgasket has failed.
This is a big job. First removing the upper intake and possible the airbox. then the fuel rail and injector connectors needs to be removed or disconnected then remove the lower intake. Possible having to remove the valve covers first.exhaust manifold(s) will have to be removed. Then you can remove the heads. There will be many electrical connectors that will have to be disconnected. Inspect the heads for cracks around the valves is where they usually crack. Inspect all valves for damage or uneven wear. ALWAYS follow torque specs and sequence when installing the heads. A manual will be verys helpful with this job. The alternator,P/S pump may also have to be removed or moved out of the way. Cleaning is very important. Generaly the parts you will need are.
Upper and lower intake gaskets Head gasket Head bolts Valve cover gaskets Injector O-rings Exhaust manifold gaskets
I had the same problem with my 1999 grand am .I changed water pump, thermostat. I heard the Pontiac engines , 3.4 had overheating problems one is the intake gasket if your losing water but don't know were its going its leaking at the intake gasket and burning off or if you check the oil cap or the dip stick and theres a milky substance on them it would be your head gasket I had to change my head gasket and while I was there I changed the intake gasket too. I haven't had any problems sence I changed them hope this helps. Jack
oil too low!!!!!!!!!!!!!!!!!!!!!!!!!!! have some change your oil & filter immediately !!! drain radiator & coolant reservoir , refill w/ fresh 50/50 coolant , white smoke is not exactly a good thing ! it could mean coolant is mixing w/ oil , because of a possible leak from a bad gasket either from intake manifold or head gasket !!! water pump would not cause this ! I would bet on a gasket leak given the age of the car . 2000 ! 13 years old, how was it maintained, intake gaskets are cheaply made, head gaskets are made well ! so, my bet, goes to the intake manifold gasket !!!!!!good luck kristle !
If you have coolant leaking out of the muffler the head gasket is most likely blown. The head gasket has passageways through it for coolant water, exhaust, intake and engine oil. Depending on which location the gasket has ruptured you can mix fluids or gasses in several combinations. The only way coolant can get to the exhaust is through a cracked head or blown head gasket. If the head is cracked and another head is installed a new head gasket is installed because reusing a used gasket is very risky. The only to be sure what is broken is to take the heads off. If only the head gasket is blown the head is usually warped and should at least be milled if not replaced. I hope this helps.
check your radiator cap condition if its ok then your engine must be having a cylinder head gasket problem, normally when engine overheats the cylinder head gasket gets fried-up and the water goes off to the exhaust along with the exhaust gas thats why u dont see any trace of leakage on the floor/ check your engine oil as well if oil and water mix together to conclude the theory.
could have a blown head gasket or cracked head or worse case scenario, a cracked block letting oil into the combustion chamber and out the exhaust. if it is letting coolant into the oil then pull the dipstick and there should be a milky white look to it where the oil tried to mix with the coolant. but its normal to have water alone drip from the drain hole in the exhaust from condesation. for every gallon of fuel your vehicle uses, it produces about a gallon of water thru the exhaust
