Ford F-150 (2004-2008) :: 2006 - Coolant Leak At Intake Manifold
Feb 9, 2014
I have a 2006 F150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head. This is on the drivers side directly under the thermostat housing. The t-stat housing is dry and the hoses all appear dry. It's just wet right at the gasket where the manifold joins the head. Reservoir is still normal so it's not leaking too much just yet.
I searched this site and youtube but didn't find any other posts. Lots of problems with older trucks with composite manifolds but nothing for this one. It looks like a part of the bottom of the manifold is plastic but the entire top and where it is leaking is all aluminum.
It seems odd that this would start in the winter time just driving back and forth to work (no load). And, yes the antifreeze is good. Just wondering if this is a known issue with this truck. Is it just a matter of replacing the gaskets or is there some other flaw I should be concerned about?

If you have a coolant leak at the y hose for the intake manifold and the thermostat, make sure you replace the upper radiator hose as well as the y hose.

I have an 06 with a 5.4 with 70k on it and I have already had to do the exhaust manifolds twice, once covered by warrantee at 19k, then again around 40k and now at 74k I have a major leak from the left side manifold again

Looking for any pictures or directions on replacing the intake manifold on the 2004 F150, 5.4. Got all the parts with the pulgs, and ignition coils.

I've got a 1997 F150 with the 4.2L V6. Before I got it last summer I did some research, but apparently missed the issue with the intake manifold gasket leaks on these early engines. It seems to be a very slow leak, but obviously I want to get it fixed. I called Ford to see if it had had the recall work done on it, but all they could tell me is that there wasn't an open recall on my truck (with the exception of the recent fuel tank strap recall). Their system apparently only goes back 10 years, so they couldn't even see the freakin' recall. So, I've got a few questions:
1) I know I didn't post much info, but does this seem like an intake manifold leak?
2) Are there any special tools needed to change out the gasket myself?
3) Can you all recommend any replacement gaskets? I found a few different manufacturers of gaskets, but I'm sure some are better than others.
4) Can this issue cause the computer to throw the loose gas cap code (P0455 if I recall correctly).
5) Would it be worth it to just get a new truck? I really wanted a diesel in the first place, but I also hate to give up on a nice truck with only 115,000 miles.

Repaired a coolant leak under the intake? I just repaired the bad o-ring and rtv at the front coolant bypass joint. But, there is still active coolant leaking around the back side of the block and puddling on the garage floor beneath the front of the transmission each night.
So, I'm guessing I need to start removing the intake to hunt this thing down, the top of the block, just under the intake is constantly moist. But I'd like to have a list of seals and parts I'll need to replace before I start.

I am mixed up in which fasteners I have to tighten to stop my antifreeze leak. For this, I got some pictures. Do I have to tighten these bolts? Or these? Is this the upper intake intake manifold?
I am just really lost and want to tighten the right bolts and find the torquing specs of the bolts. In the first picture, we can clearly see there is a leak there of what must be antifreeze. The stuff I have been loosing slowly over months.

I have a 1999 Ford Expedition. A couple of days ago The engine started losing coolant as soon as the engine cooled. I replaced the coolant only to lose it again when the engine cooled. I was told that it is more likely the intake manifold gaskets leaking. It seems they are right. What is the cost to repair if I take it to a mechanic?

I have a 2001 F150 Super Crew 5.4. I had a leak where the water transfer connects to the intake manifold. I decided to get a new manifold rather than trying to repair it. The new manifold from Dorman came and the gaskets were built into the manifold. I torqued the manifold to specs. I replaced everything and it starts fine.
I can hear what sounds like a leak, but can't find anything. I checked every hose that is connected and they are all snug and connected. I had the check engine light checked and it said it was running lean on both sides (p0174, p0171). Also a p0122. I thought something might have damaged the Throttle Body Position Sensor, so I replaced it...but no change.
I'm still driving it everyday because I need to. It won't change gears so smoothly sometimes. The most noticeable problem is that the A/C doesn't work. It just blows hot air. And the worst part about it is...it does it even when the air isn't turned on! I just go around with the windows down...in 95+ degree heat...with hot air blowing!
This is my first time to attempt a manifold change out. What I should check?

Truck has 107 thousand miles; had to take it in for an manifold exhaust leak. Mechanic said bolts are so rusted they break.
1) was there ever a ALERT from ford about these bolt's?
2) Thought i read ford had stainless bolts for this problem...
I've had F150's only since the mid 70's and this 04 has cost me more in repairs than ANY previous F150..

2004 SCrew, FX4, 5.4 ... I had the dreaded exhaust manifold leak on the passenger side. After reading the horror stories of this repair and living in the rust belt I decided against fixing it myself. I took it to a local repair shop to have done. Initially the mechanic could see that the front 2 studs were snapped off (before even trying to remove them).
After a full day of fighting the studs (engine loose & lifted up) everything is out but the front 2 studs. the top one has about 1/2" exposed, but it is frozen in place (penetrate on it overnight). The biggest problem is the bottom stud. it is broken off about 1/8" below the surface of the head. The guy doesnt have a small enough right angle drill to get between the frame & head to attempt to drill it out. I will gladly go buy a drill for him to do this, as it will likely save me money if it will work to drill out the stud.
Need to get the 2 studs out, particularly the bottom one, or what right angle drill may fit in there?

I have a 94 ranger and all of a sudden it started sputtering, i can hear a vacuum leak behind the intake manifold found what appears to be a pcv valve not hooked up is that the way it's supposed to be?

My friend and I are working on her '03 1.8t and I noticed a huge oil leak under the intake manifold. It looks like there's a tube that has broken off and is now just spewing oil all over the place. I tried to get pics the best I could, so here they are....
I'd imagine its something that needs to be fixed asap.

I have a 2000 Pontiac Grand Am SE sedan (base model) with a 3.4L engine at 142Kmi that was just diagnosed with an intake manifold coolant leak by an independent shop.
I've done some googling and found that this is a known problem with this engine (including a class action suit). So far the leak is just external; no coolant in the oil and no oil in the coolant.

When I got my 60K service last weekend, the dealer called me and explained that I had a "very small internal leak fro an emissions canister that was leaking into the intake/manifold". He said something like that. He also said that it doesn't do anything to the performance of the car, but that the leak will increase over time and will throw a MIL.

My 2003 f150 4x4 w/5.4 has 220k miles and only minor issues until a few days ago. I now have a coolant leak at the mating surface (both sides left and right) of the aluminum crossover coolant manifold (holds thermostat on one end). I have most of the bolts out to remove the crossover manifold but there is one bolt on the RH side that comes from the underside. All things equal, main question is... Can that crossover mainfold be removed independently from the intake? My thought is that in order to get to that last single bolt (there may be others I am not aware of yet) that I will need to remove the intake.

I have a 1998 Ford f150 4.6 2x4 i have a coolant leak on the upper intake. It comes out on the back left of the intake through a metal pipe. Well where the metal pipe is (pressed in) to the intake. Now i talk to the guy at ford dealership in the parts he said it is called the (heater pipe). He also told me that the part is 21 dollars but I have to press it in and if that does stop the leak he said I would have to buy a new intake. Now here is the problem I can not find any info regarding this heater pipe. I don't know how to remove it properly, why it is leaking. I can't find it in the handbooks that i have read so far.

I currently have a S&B Intake on my 2006 f150, 5.4. I am selling my pickup and getting an 08 with the 5.4 and am in the fortunate situation to be able to have both vehicles with me currently. Question, would i be able to swap the intakes? Place the stock intake form the 08 on the 06 and the S&B fit the 08? I know the pickups are nearly identical, but just want a little clarification.

I just replaced the oil/egr cooler, stand pipes and dummy plugs along with all suggested upgrades, just filled with oil hooked up batteries and while filing with coolant it started gushing out from under the intake in front. I think I see an o-ring pushed out.. I hope I can lift the intake without removing the turbo!!!
