Most likely it is a separate piece. It could be threaded on or simply a press fit. Unfortunately, that particular piece is hard to find as most auto stores won't keep it. It can also be difficult to change out if it is press fit and may cause more damage if done incorrectly.

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.

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!

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...."

97 grand marquis - appears to be copper nipple at top of block behind water pump w/ hose going back and under the intake manifold. Nipple is leaking just at joint of nipple and block. was told by shop...


Why would a repair shop, tell you after
looking at your vehicle, that the intake
needs to come off. You don't believe
them? You didn't see the issue as they explained
it to you?

There is no quick or cheap in this
world, for anything done correctly

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.

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!

Cant find bleeder valve foe coolant system on 96


dr_greg is incorect. The bleeder valve is on the thermastat housing near the intake manifold. Follow the hose from the top of the radiator to the the engine. Look for something that looks like a 12mm head nut with a metal nipple comming through it. If you change your coolant but do not open this valve untill coolant flows from it you may cause an air pocket to remain in your engine, possibly causing your car to over heat.

Running Lean


if the engine is still running lean, I would replace the Oxy sensor (s),
Then check for a vaccum leak, I found a very large leak on my intake manifold... there is a cap on a nipple on the engine side lower intake manifold (very difficult to get to) and I could not see it until I removed the intake and looked at it.
On my engine, this cap made of rubber was rotten and leaking vaccum.

This helped me 100%
