Check water pump hose and the pump. a clogged thermostat can cause pressure build up and bust hoses. and of course take radiator out and check for lower hoses and crackes. if no luck, put water in radiator and run car and check for leaks. small cracks in aluminum are hard to see but expands when radiator gets hot.

SOURCE: Thermostat on 2002 Chevy Impala

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

SOURCE: Leaks oil looks like from valve cover

You have to remove the spark plugs cables and remove the four nuts that you see when the cables are removed.

When the four nuts are removed, simply raise the valuve cover. When replacing the gasket, make sure you get the gromets as well. Those sometimes get worn or crack since they are more exposed than the value cover gasket. Make sure that you clean the cover from oil and replace the gasket with no use of silicon.

Good Luck.

SOURCE: how to replace valve cover gasket on a 2002 stratus 3.0 liter engine

i don't know that vehicle very well... but there are usually bolts/screws that hold them in place. 4 to 6 of them per cover. sometimes the spark plug holes have giant nuts that hold the cover in place.

SOURCE: intake valve gasket leaking how do i replace

He must have meant the intake manifold gasket. That is a complex job, but can be done if you have basic knowledge of mechanics and a few hand tools. Best advice is to get a haynes repair manual from an auto parts store as it will have step by step instructions and photos. Good luck. Dont forget to rate.

Replacing the valve cover gasket on a gm 3800


support engine and remove front engine mounts, you'll have to remove your upper intake and some EVAP hoses, some other parts mounted to your intake and your ignition module from the rear valve cover the bolts should be either 8mm or 10mm, make sure to clean the valve cover of all old gasket material before reinstalling with new gaskets!

Hello, i have a coolant leak i thought it was the water pump but the leak is above the mount bolt of the water pump beside the valve cover no coolant has gone in the valve interior, could it be a cracked...


A crack in that area of the block, while possible, is highly unlikely. A crack in the block usually happens in between the cylinder walls on the side of the block. It is most likely leaking from the intake manifold gasket that connects the intake manifold to the heads, or if the upper radiator hose connects to the intake manifold, it could be leaking from the thermostat housing or hose. There are also coolant temperature sensors that are mounted in that area. Or last but not least, it could be leaking from one of the freeze plugs in the end of the head. Coolant runs through the block, heads and intake manifold.

P0302 is random misfire on cylinder #2.

Most comment cause is vacuum leak at the intake manifold and vacuum hose.

If you valve cover is leaking oil on then DO THE HOLD JOB.

Remove valve cover to gain access the intake manifold.

Change the intake gasket and valve cover gasket.

Coolant leak at intake 1994 Buick LeSabre 3.8 ltr


There are several areas of possible leakage. One is the hose and plastic outlet from the intake manifold on the passenger side of the engine. The hose runs low, underneath the alternator. The plastic outlet cracks, the hose gets old, the clamps on the hose can also be loose. The replacement outlet from the dealer is steel, not plastic.
Another possibility for leakage is on the driver's side of the intake manifold. Underneath the air inlet is a metal cover on the end of the intake manifold. This covers the coolant passages at the end of the intake. Mine was oozing antifreeze..you don't have to pull the intake to replace this.
The other place for leaks is the intake itself..requiring removal of the intake. I've done this...I don't think it is that bad of a job. However, if you put in a new intake, don't forget to put in a pcv valve..it fits under a small cover at the right rear of the intake manifold.

1999 Pontiac Grand Am with "lower intake leak"...What does this mean specifically? Would this mean the intake for the radiator, gasket, or valve?


Usually intake has to do with the induction system, as in intake manifold , The intake manifold can have several types of leaks, the intake can have a vacuum leak, oil leak, coolant leak or a combination of any of the before mentioned....hope this helps,
