Ford F-150 - 1997-2003 :: Coolant Bubbling Out Of Front Passenger Side Of Intake
Feb 9, 2014
Two weeks ago I was driving home from work and my heat stopped working. I pulled over and saw coolant dripping badly out of the bottom of my truck. I popped the hood and sure enough, coolant was bubbling out of the front passenger side of the intake. I took it to a shop to do the work (quoted at 500-550 out the door with a dorman intake). A week goes by and I get a call from the shop, "After two Dorman Intakes, the truck is not running right", what it could be.
The truck has 367k on it (not sure if original motor). Yesterday I get a call from the owner, " we put the original intake back on and fixed the leak with jb weld. The truck still runs bad. They claim they didnt do anything wrong and will not take any blame for ruining my engine. (Keep in mind the truck ran PERFECT when I took it in there). The truck doesnt throw any codes and they are at a loss of what could have happened. They put in 8 new plugs and 2 coils that they broke while in the process of removing the intake. F150 5.4 ...

I have a 1990 F-150 w/351 that I knew had a coolant leak at the back of the engine when I bought. It's a tinker around truck, something for me to play with.
I've traced the leak back to a metal tube/pipe that sticks out of the engine compartment just below the AC housing. I cannot find anything in the Haynes manual or a diagram on the intertron that shows what this is and if it should have a hose on it or...?

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.

2003 F250 7.3... I noticed a water leak dripping down onto passenger side front leaf spring. I saw this before but attributed it to the AC (which kicks butt) but haven't used the AC. No scent to the clear fluid, temps all look good. Running fine. Where does the AC discharge go? Could AC be on (not on AC but set in blue zone on dial)? Reservoir looks ok but could e small volume of drips.

On my 2003 Excursion 7.3L, I notticed I'm leaking what I think is coolant from the passenger side rear hard line by the front spring hanger. I haven't pealed the plastic loom away yet, but I did see the loom is chaffed near the spring hanger. What lines are the ones that carry coolant, and can I just cut the hard lines and replace with a section of rubber hose?

I have a 03 5.4 F150 SCrew... The intake was leaking on the passenger side (water outlet tube meets plastic).
Putting in the Dorman replacement and noticed that the front cylinder drivers side (#5) had a decent amount of coolant in it.. None of the others did. I've drained the coolant already and was wondering should I just put this back together and see?
The water outlet crossing has a hole right next to this cylinder and I can't see any cracks and not sure if the gaskets were leaking under it.
Seems like if the head gasket was blown I would see it in more cylinders? It never smoked or run bad before I got this leak... Drove it maybe 10 miles with it leaking out onto Cyl#1. Ran fine, never missed.
I just don't want to put this back together if the head gasket is blown but I don't know what to do.

I'm trying to figure where the coolant leak is. Appears to originate on the driver's side front, right near the thermostat housing. Since the engine tilts back the entire drivers side is wet. The thermostat gasket appears to be OK, but it does have a lot of miles on it.
If it's not the thermostat then can coolant leak from the cross over tube. And is the cross over removable without taking off the intake. There appears to be a bolt coming up from underneath on the passenger side.
Also, does coolant flow through this plastic intake. If it does, then the leak could be some where else, if not, then it's probably the thermostat.

At least this is how I did it after a P0133 code.
The back ground on my truck (see sig) is that I am the second owner (my former neighbor was the first) and it has 293K miles on it at the time of this post. The truck is bone stock FWIW.
I searched the internet and couldn't find a good step by step replacement write up. The front oxygen sensor on the passenger side is hard to get to so here is what I did:
Jacked the truck up and placed jack stands under it. Removed the front passenger tire and the plastic wheel well liner.
Tools needed for this part are a 7/32 socket and a trim tool remover (for the plastic push in fittings).
There are 5 screws and 3 or 4 plastic push retainers (don't know actual term) to remove.
Because of the location of the sensor I had to remove the transmission dipstick tube. *If you do this have a pan or bucket under this area as you are going to lose fluid* the dipstick tube is held place by an 8mm bolt about the middle of the exhaust manifold. Unscrew it and with a little pressure the tube will pop up and out, and so will some fluid.
Wheel well liner out and dipstick tube pulled out of the way.
The connector where you will disconnect the old 02 sensor is tucked up behind the engine block and is kind of hard to get to. A little time and patience and you can get it separated.
From underneath the truck I cut the end off of the old 02 sensor (because the closed end of the wrench wouldn't fit over it) and used a 7/8 box wrench to unloosen the sensor a little at a time until I could get it out with my fingers.
I put the new 02 sensor in finger tight and then tightened it down with small turns of the 7/8 wrench until tight
The cord on the new sensor is longer than the factory one so once reconnected I used zip ties to keep the slack up and away from the hot parts.
New 02 sensor installed and dip stick tube back in place. Note the attachment approx 1/2 down the dipstick tube. It is the 8mm bolt I previously mentioned.
Wheel well back in place. Truck lowered back to the ground.

My '02 F150 just developed an oil leak. It appears to be coming from the passenger side front. I'm just assuming here, but could it more than likely be the timing cover? I'm 150 miles from home and I'm debating on getting the timing cover gasket on my way home tomorrow. Also, if it is the timing cover, what other gaskets should I replace? Pretty sure the water pump oring.

I have a f150 with a 5.4L with 354,000 miles on it. It started leaking water somewhere on the front of the motor on the passenger side. it looks like it is under where the heater hose connects to the intake. I guess my question is can the water eat a hole in the intake?

Have a 1998 F-150....heard a strange noise coming from the front passenger side of the truck. Parked and turned the wheel and heard something fall off. It appears to be a shield of some sort.

Had crunching sounds from front passenger side. Replaced CVJ shaft and hub bearing/assembly noise gone but tire turns hard by hand drivers side turns freely. Looked on line and guy had same thing going on said maybe 4x4 vacuum actuator might be bad and truck stuck in four wheel .does this sound right? I have manual trans and gear box so I don't understand why the actuator is even there.

Working on a 2000 F150 with the 5.4 and as near as I can determine its leaking antifreeze externally at the front of the passenger side head gasket. Seems a little odd. The coolant is a nasty dirty orange color. With the truck running on the hoist it was dripping very steady off of the very front exhaust manifold bolt.

I have a 2001 expedition 5.4 ltr that has developed a coolant leak. Leak appears to be on top of the engine, in front on passenger side. The area around the front fuel injector (on passenger side) is wet and water is running down and sitting on top of engine (under intake manifold). My first thought was that the heater hose extending vertically from the block hose fitting. I have found no evidence of a leak in the hose but it appears fitting on block may be the source. It has three bolts holding it onto the block. One from the top and two coming up from the bottom. Two of the three area accessible. How to get to the upside down bolt nestled between hose fitting, block and valve cover. It's been a slow leak so far but I know that's not going to last. Runs fine but steams from water on block at stops and when parked.

So, the other day, I went outside and there was a puddle under the truck. It had been sitting for a couple of days, IIRC, so I thought it was strange. It rained since then and the driveway was dry one day later, so I didn't give it much more thought at the time. Then the puddle appeared again. Went out with a flashlight this evening and looked around. I remember there was moisture in a couple of spark plug holes when I replaced them. Some of it was oil, but one was definitely watery. So, I am not surprised that there is a leak somewhere.
But what I do find strange is the location of some of the puddles, and where it drips from. I guess since the motor slopes down as it goes back, maybe the leak is really at the front and it's just running down the head next to the intake to drip from the back of the motor? There is water next to the intake manifold there, to support that theory. But there is a puddle on top of the intake around the #1 injector. How does it get there? My pressure tester is one of the old ones that attached to the radiator neck, so I'll have to find another way to pressurize the system to look? It doesn't seem to match up to descriptions I've seen of the crossover tube or the heater/water pump tube.
Coolant dripping down the back of the motor from the passenger wheelwell. Puddle around injector.

2003 7.3 175,000 miles...
Saw a stain in my driveway where you normally see AC drip. Opened hood and saw degas empty.
Looking around like crazy and find wet area. Where the coolant line turns down beside the passenger fender.
Looks wet near bend going toward running board. Didn't get to inspect much but I pulled back a bit of loom to inspect shape of lines and they look great.
What could be going on?

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!!!

I have a 03 250 gas 5.4 trying to find out the cooling system problem. I've found what I've read to be common oil leaking from back of passenger head. I had never noticed this before but it started very slight now overflow started bubbling over.
There is no coolant in oil no white smoke. My cooling system leak is just head gasket and gasket change could solve the problem or should I did deeper?

I have a 2003 Expedition with a coolant leak on the front R/H side of the truck. I do not see any coolent lines on that side of the truck and the leak seems to be running off of the A/C compressor. I notice a couple of drops about the size of a dime about once a week in my drive way since x-mass and have NOT had to add any coolant. I was getting ready to do a flush and fill but now have concerns that it may have a bad head or head gasket. The truck has 84000 miles on it and never has been overheated.

I have a leak on the right side of the cross over pipe. I removed one long bolt from the right side and two long bolts from the left side that go through the thermostat housing, and three bolts from the back of the alternator, but the pipe doesn't seem to want to move. I don't want to break anything.
