Your most likely problem is your thermostat, replace that and if is does not fix it, flush your radiator and take off all hoses and be sure they are clean of build up.

What does it mean if there is oil in my coolant reservoir


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 !

Hello, Probably the easiest thing to do is drain the oil and see what it looks like. If it is okay, then invest in a new oil pressure sending unit and change the oil filter. For awhile there were bad Fram filters and others with bad relief valving in the oil filter.

If the oil has Antifreeze in it, then it is pretty much a given that a head gasket is bad. You should check your sparkplugs anyway for signs of water/antifreeze contamination if the engine is blowing the Antifreeze out of the exhaust. This can help show you if only one head gasket is bad or if both are bad.

I hope you either bypassed the heater core or fixed it. Another gasket that can get Antifreeze into a cylinder is the Intake manifold gasket. The newer cars usually have only air coming into the engine through this manifold. You need to look at where the top Radiator hose enters the engine. If the hose enters on the block, you are probably good for the Intake gasket.

But if the top Radiator hose attaches to the Intake manifold, a loose Intake can leak Antifreeze into the heads through the ports on the Intake. It can also cause a lack of power and poor idle. If the Intake gasket IS your problem, the head gaskets can be fine. The Intake gasket is reasonably inexpensive.

I can tell you that a loose Intake can be checked for air leaks by running the engine and spraying a water mist from an old detergent bottle around the seams of the Intake. The engine speed will change or stall if the water is drawn in. The Antifreeze leak can not be checked by this method.

I hope my solution helps you find your problem.

Manifold water leak on 2002 blazer how do you get to it


This happens a lot with chevy engines 305 s 4.3 s its means the intake manifold gasket is leaking because the engine over heated at some point . Cheak your dip stick if you see a white fomey residue on the stick then look inside the radiator cap if you see oil floating on the top of the antifreeze it means oil and antifreeze are mixing this will kill the engine real fast so stop drivering it and have the intake manifold gasket replaced . ALso check for any other sorce of the antifreeze like a radiator hose or a gasket on the goose neck hopfuly you will find something else that easyer to fix but its a disgin problem with chevy they don't have enough bolts holding the manifold down theres 8 and there in the corners 2 in each well good luck with it

My 98 subaru forester is over heating


Change the gasket is a must. You don't want antifreeze mixing with your engine oil. The antifreeze is carrosive to the engine bearing. The other thing to is if your radiator hose is soft and lod, they can and will collapse ristricting the flow of antifreeze.
Last to look at would be a weak water pump and you are going to have to change that.
 Start with changing the radiator hose since it's the cheapest. Keep an eye on the oil antifreeze to make sure you aren't have the two mix. 
Change the intake manifold gadket soon as posibel.
Good luck and hope this helps.

Lower intake manifold gasket leaking 02 Olds Silhouette


This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck
