Coolant leaking in and around the intake manifold as well as the under carriage of that same part I think. Outake? I know that the part that attaches to the manifold appears to be metal but the manifold appears to be plastic. Can this be the problem?

The plastic piece is the upper intake manifold. The metal part is the lower intake manifold. Sometimes the gaskets go bad between the upper and lower intake manifolds. But usually the upper intake manifold is cracked and needs replaced.

Location of freeze plug on 2001 malibu


I had a 2000 malibu 3.1 and the manifold gasket was leaking. Model years affected, 97-04. Check the recovery coolant tank and if it looks like a milk shake instead of coolant, then you have a bad intake manifold gasket. I replaced mine a few years ago and all was fine. Engines affected are the 2.4-3.1-and 3.5, look very carefully around the intake manifold and you will see it if its leaking! operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks. Because oil will mix with coolant if gasket is bad. Hope this helps you out! Good-Day!

Tip

Intake Manifold gasket replacement and/or leaking= Ford


Intake Manifold gasket~

Replacing intake manifold gasket:
Replacing the intake manifold gasket, I used the tube kind, it's a make it youself for about $6 (it's blue and the consistancy of toothpaste) follow directions carefully! You can get a tube at Autozone or any car parts store. Has been working great. Just ask the cashier for the make it yourself kind of intake manifold gasket. Sorry, I don't remember the name of it, it's been that long...lol...

As for the Intake Manifold leaking coolant....It could, but shouldn't. One of the largest problems I've seen for coolant to leak out the Intake Manifold has been due to pressure in the system somewhere... Check the classic area:
Water pump- look for either water seapage and/or coolant. You'll know if it is because you will see real water either coming out of the water pump leak hole or under the thermostat. Most of the time coolant will pool where your heater hose runs in the intake manifold.

Mentioning heater hose. Check for leaks, holes, and/or cracked heater hoses. In-addition to the water pump, heater hoses...Check the transmission system, exhaust system, fuel system, radiator system, A/C system, secondary fan (located above the water pump housing), and thermostat.Also, check all electrical connections....Hummm....This is almost the entire workings of the vehicle.

NOTE: "It seems to be an infinity kinda thing... Once one thing starts to fail and is ignored, you are bound to be fixing a chain of event failures. Therefore, Do not ignore even the smallest problem or you'll be bound for life in repairs...."

My 2008 Chevy uplander engine light on and the code shows for cam shaft sensor and intake manifold what I do


The intake code means its leaking from the intake,bad gaskets, or a vacuum leak. check for bad gaskets on intake manifold. You can tell by putting a bit of oil around the maifold. if it is leaking the engine will flair up. To check this, External leak-- Coolant seeps through the broken intake manifold gasket to the outside of the engine. If its bad enough you will see coolant dripping from gasket. Coolant seeps through the damaged gasket to the inside of the engine, mixing with motor oil. If you suspect an internal leak, check your oil dipstick. Or if you have a substance under oil filler cap that looks like a milkshake, Oil is mixing with coolant. this means intake gaskets are bad, Now for the camshaft sensor, If you have a manifold leak. this could be giving you a false camshaft reading! Because, If sensor is bad vehicle will not start unless theres a wire problem. Symtoms of a bad sensor are--- engine sputtering, poor acceleration, stalling/inability to start. HopeI helped you out! Good-Day!

My 2001 Daewoo Leganza is leaking coolant I am unsure of what this part is called, I'm thinking the coolant manifold maybe... and I am unsure where to purchase parts.


coolant manifold? No, no such thing. Is the leak coming from engine? Only manifolds there are the intake and exhaust manifolds. Your intake might have a small coolant line (smaller than a garden hose size) running to it. You just have to find the leak to know what to fix. As for where to purchase, any reputable parts store: Napa is my first choice, followed by discount retailers (O"reilley, etc.) Just be aware that discount places and their parts vary in quality.For major parts, buy from the dealership for OEM (original equipment manufacture). For minor parts and maintenance items, shop around for best prices.

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.
