SOURCE: coolant leak

You may want to check it with an ultraviolet dye and light kit.You can get a kit from a good auto parts store and do it yourself. They have dyes for every kind of fluid a car has. A very handy tool and not very expensive either.

SOURCE: intake manifold leaking coolant at expansion tube nipple

It is pressed in. I usually just take the nipple out and run a threader into the hole and place a piece of threaded copper pipe into the newly tapped hole. The factory uses a thin steel tube and they rust out if the cooling system is not properly maintained.

SOURCE: water leak under the intake manifold,1995 toyota 4 runner

There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

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!

What are the symptoms of a bad intake gasket on a 1999 buick century?


Coolant leaks,When the intake manifold gasket cracks or blows out, coolant will leak out of the intake manifold. You may see puddles underneath your car or notice smoke or steam coming off of the engine and exhaust from the coolant dripping onto it and then burning.Overheating, If the intake manifold gasket fails and allows coolant to leak out into the engine, your car will begin to overheat. If your car frequently runs low on coolant or begins to overheat, check the intake manifold gasket.Running poorly, When the intake manifold gasket falters, it affects the way the motor handles its emission gases. The change in pressure can affect the vacuum in the intake as well as how smoothly your car runs. Mainly, it will idle roughly and may hesitate, cough or sputter.

Pontiac grand prix gt 3800 dexcool leak


Do you see the coolant leaking on the motor? From the drivers side, you can inspect the intake manifold...unfortunately as good as this motor usually is...it is known for leaking at the intake manifold...and requires a new intake gasket...DO NOT USE dexcool after the replacement...many teams believe the dexcool is part of the problem...use the coolant that "For All Coolant Systems" is still the green anti-freeze...Hope this helps.

Leaking coolant somewhere below after car is warm and shut off can not find,recently replaced water pump, and it is not the radiator


Does this vehicle have a 3.1 or 3.4L motor. If so they commonly have intake manifold gaskets failures. This leads to coolant leaking, usually at the corners of the intake manifold and in some instances leaking into the oil. Look for signs of coolant leaking at the corners of the intake manifold and check the engine oil for coolant.

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.

If it is not necessary to replace the coolant tube in the intake manifold if it is leaking antifreeze, how do you fix the leak even if you do flush out the system and put green antifreeze in? I am also...


I'm assuming you are talking about the 3800 v6 engine?
I don't know what hose or tube you are talking about either. There is not any coolant going through a hose in the intake manifold. There are two bypass coolant elbos on the passenger side of the engine going into the intake and timing cover from the intake and the heater core. Is this what you are talking about.
And NO green coolant in a 97 Dexcool only!

Coolant leak


This engine has a plastic intake, jsut inside of the throttle body is a tube that comes from the EGR. It will burn through the plastic into a coolant passage located inside of the intake. You will need to replace the intake manifold and if you want there is a revised lower intake manifold with a slightly smaller diameter tube to prevent future burn through that will prevent a reoccurance. However, it is a costly repair for what is a infrequent failure. I suggest just replacing the upper intake manifold. They are now available through the aftermarket.
