Ford F-150 - 1997-2003 :: 1998 4.6 Triton - Slow Coolant Leak - Head Gasket?
New truck to me. Truck was advertised with a slow coolant leak. Figured I would trace the leak down and get it repaired no issues. Anyway, working on it this evening I take a close look around the oil filler area and notice the dreaded milkshake color.
I drained the oil out of the truck and the oil actually came out nice and black. Is the headgasket the only area that would cause the oil/coolant mixture? Supposedly the truck has never been overheated.
At any rate, on to find articles on how to pull apart a 4.6L Triton head. I'll see if I'm up to this challenge.
Ford F-150 - 1997-2003 :: 1998 5.4 Motor Won't Stay Running
Got a buddy with a 98 white f150 with the 5.4 motor. It will start up and idle fine but if you try to drive it it has no power what so ever. What it could be?

I can cold start my 98 f150 with the 4.2 and it runs fine. After you drive it for a while and turn it off and try to restart it, it starts then dies, it will do this until you rev up the motor to keep it running. I have to drop in gear and get going down the road and then it smooths out and runs fine. I had a mech check the fuel pressure at the rail and it was 19 psi. The book says it is suppose to be 35psi. He said my fuel pump was bad. I installed a fuel pump and it is still doing the same thing yet. What to check now?

Vehicle is stranded on the side of the road (safely) and here's what happened. Driving (normal) 1/4 mile away from the house, motor shut down. Pulled off, tried restart. Motor turns over normally and all gauges work (temp/oil/volt). The only weird thing is that the O/D light on the end of the shift selector stays on even after pushing it on and off. I plugged in my OBDII reader and it will not link with the system. Yes... the ignition is on Is this indicative of a fuel, computer, electrical issue? or all the above. Worst case scenario is i have it towed to the shop tomorrow and they diag it. I don't have the proper tools to diag this.

I suspect I have an oil leak where the oil pump mounts to the motor.
It looks fairly simple to replace, but I was reading in the Haynes manual something about the timing chain?
So I don't know if it's more involved than I think.
Ford F-150 - 1997-2003 :: Coolant Dripping Down The Back Of Motor From Passenger Wheel Well
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.

Ford F-150 - 1997-2003 :: Water Leak Somewhere On The Front Of Motor On Passenger Side
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?

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 an 1998 F150 4.6L V8 that is using coolant. I recently replaced the radiator because of a leak in the lower right side. Vehicle has about 190000 miles on it. The vehicle is using some coolant, but no apparent leaks. When I warmed up the engine after replacing the radiator, liquid dripped out of the back of the muffler - rusted out.

Ford F-150 - 1997-2003 :: Leak Where The Coolant Leaves The Head
I have a 2001 F-150 5.4 engine. There is a coolant leak where the coolant leaves the head. Looks like a new gasket is in order. The part that needs to come off crosses over to the driver's side and the thermostat mounts into it. To remove this part and replace the gasket, it appears that most of the top of the engine, throtle body, fuel rails, intake, etc., will have to come off. One of the four bolts holding the part on is installed with the bolt head facing down. The only way I see to get this out is to take everything apart.

My '02 F150 180k X-cab with the 5.4L is leaking coolant when it is shut off. Its just pouring right out.It looks like it's coming from top of the trans and around the firewall area. I had to replace a drain plug already.. the one behind starter ..its not leaking.

My truck is leaking behind the engine. There is not any coolant on top of the engine. It's leaking above the transmission and running down the passage sides. Are there any hoses that could be leaking behind. Sometimes it leaks a lot other times it doesn't leak at all. The shop thinks it's a freeze plug but wouldn't it be leaking more if it was?

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.

Only when running heat or defrost, coolant leak looks like it's coming out of the bell housing. I have a supercharger so very difficult to see behind motor, but with inspection camera, heater hose lines look dry. firewall looks dry. No coolant in cab. No steam on windows or smell. Pretty sure not casting/ freeze plugs because absolutely no leaking with heat off. Can run for days with no loss, then turn on heat and within minutes/ seconds coolant puddling in driveway. Is the hose that runs through valley pressurized only when heat is on? I saw a few older threads but as far as I could tell none specified heat on/ heat off conditions. Just started problem after doing some other work, hoses were off radiator and intercooler, replaced radiator. None of those connections are the culprit.

Ford F-150 - 1997-2003 :: 1998 V6 - High Beams And Coolant Gauge Not Working
I just bought a 98 F150 V6 Manual transmission 2wd truck. Its a clean truck and I'm liking it so far but its got a couple minor issues. Whats the point of buying a truck if you don't get to work on it??
The High Beams don't work at all. Low beams are fine. I've put new bulbs in, and fuse 16 in the passenger compartment has continuity. I'm suspecting the multiple function switch, because when I pull out to engage the high beams, nothing happens. The indicator on the dash doesn't come on, and the low beams don't turn off either.
The second issue is the coolant gauge doesn't read. When I turn the key to the on position, the needle on the gauge moves up just a bit, but it never moves after that. Anything to check?
There are a couple other minor things like the e-brake light on the dash doesn't always turn on, but I can deal with that.
Ford F-150 - 1997-2003 :: 1998 - Oil Leak / Constant But Slow Drip?
I have a 1998 f150 xlt, supercab, 4x4, 4.6 Romeo (truck production date is 12/97). And I have a oil leak.
Its on the drivers side of the engine. There is a nipple on the head, next to the firewall, directly above where the exhaust pipe and exhaust manifold meet. It looks to have some sort of bolt/flush stud inside the nipple. I have oil seeping by the bolt/stud and leaking onto my exhaust pipe. its a constant but slow drip.
What this is or how to fix it? Is this a common problem? I can take a pic but cant find my camera at the moment.
Ford F-150 - 1997-2003 :: 2001 - Coolant Smell - Can't Find Leak?
I have an 01 supercab. 5.4 Triton 135k. I have begun to smell coolant the last couple of days. Have seen nothing leaking and truck doesn't run hot.
Will investigate more this weekend. Where to start looking for this. It has to be leaking somewhere. Windows don't fog and the smell is there all the time. I live in florida so don't use much heat.
Not the heater core. Heat works fine and no smell from the vents.
