Question about 2003 Pontiac Grand Am

1 Answer

I have a 2003 Pontiac Grand AM. It has a 3.4L V6 engine and I have a small water leak around the alumium pipe that comes out of top of the intake on the front of the motor and runs across the top of the intake. I have had the gasket on this intake replace about 8 months ago. This is a new leak. I took this in to have it looked at and the mechanic is telling me the whole intake has to be replaced not just the pipe because it is machined pressed into the intake. Do you have to replace the entire intake to fix this leak?

How's your oil? Is the level high, or is the color milky? You've basically replaced your cooling system, all that CAN be wrong would be a corroded block [unrelated to anything you mentioned] or an internal leak. If the heat sensor loses contact with the coolant, it'll go nuts like that. And I'm guessing that could trigger the computer to go into panic mode. I suspect a leaking head gasket. Not that bad if you fix it yourself or know someone who will do it for friendship.

You may be suffering from a warped manifold. Did this problem arrive over time or after engine work involving the heads? Remove the manifold and take it to a machine shop to verify warpage. They may be able to resurface the port areas without removing too much metal. Hopefully, a doubled gasket set will replace the removed metal. If not, another manifold is in order.

Why does my 2000 pontiac grand am leak coolant


coolant leaking could come from different areas, i would 1st start checking for leaks around the thermostat area, this is normally where the top radiator hose connects too, then i would look at the water pump area to see if any coolant is visable on the outside of it, also check your heater hoses for leaks too, some cars have even had antifreeze leaks coming from the freeze plugs, which are installed into the engines block, they are normally on the sides of the engines. don't forget to check out the radiator, a good way to find antifreze leaks is after you drive the car for a while, and then park it, and then put a large piece of cardboard under your car, make it large enough to go from the radiator to at least the windshield area, if it leaks then, you will be able to see what area the antifreeze has leaked.

I have a 96 grand am and it started leaking coolant from somewhere around the manifold, i can't tell exactly where it's coming from. Does anyone know it that could be the termostat?


If its a v6 engine and the leak is by the intake manifold, then you need to replace the intake manifold gasket. This is a very, very common problem on all of GM's v6 engines. It will cost you about $350-$400 for this repair.

Where is the thermostat located on a 2003 grand am gt 3.4 V6


The thermostat is located just under the exhaust manifold you will see that a metal pipe leads from the water pump to where the thermostat housing is. You must to remove two screws from where this pipe meets the housing and it is a pain to do unless you remove the exhaust manifold or have small hands.

I suspect you have a leak in the heater core. When you turn the heater on do you get a sweet smell and or any fog up by the windshield for a short moment? Is this water possibly green or orange, If it is the heater core the liquid would be the same as the coolant in the radiator.

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,

I have a 2001 grand am v6 that I have to add coolant every few days. The engine is running a normal temp, and the cooling fans are working.


There are only 3 possibilities:
1) Coolant is leaking on the ground - puddle under the car.
2) Coolant is leaking into the engine crankcase - engine oil is "milky" looking.
3) Coolant is burned during combustion process - defective head gasket or intake gasket.
Let me know what you find and we will go from there.
Regards,

Water on top end of engine below intake cover


This may not help, but my 1990 Ford Bronco has a small coolant line running through the throttle housing,(which I bypassed after the metal pipe broke)- "IF" you have a similar setup, maybe it is cracked on the interior and leaking in that way.
