Ford - Explorer :: 1992 - Coolant Leak At Front Of Engine Above Water Pump
Apr 13, 2004
My 92 Explorer 4WD has a coolant leak somewhere at the front of the engine above the water pump. I assume it's the lower intake manifold gasket leaking. The engine has 170k miles. I'm also seeing a small amount of white smoke, possibly steam when the engine is running. It's somewhat heavy when I start it up but mostly goes away once warm, so I suppose it could be steam, but could be coolant from either a head gasket leak or lower intake leak.
I also get a lot of water from the exhaust dripping on to the floor and the smell of the exhaust could be that of coolant, it's hard to tell. There is no coolant in the oil. I was wondering if I should go ahead and change the head gaskets while I have the intake out. Is there anyway to be certain the head gaskets are fine? I'd hate to change the intake gasket to find out there's a small leak in one of the head gaskets.
One other thing: I failed emissions because my CO was too high, but my HC and NOx were very low. Could this be an indication of coolant entering the combustion chamber? Just wondering why my CO was so high yet everything else passed (Massachusetts emissions).

1994 - 3.0 .... Back behind the water pump there is a stream of coolant what could that be. Water pump has been replaced earlier last year I thought that fixed it,there has always been a mystery leak..

Noticed about a gallon of coolant on my floor the last 4 days. Got it pressure tested and was told bad water pump. Had it changed with timing belt and tensioners. Got home, next day, same thing. Coolant everywhere. Also, do I really need to put G12++ in as coolant? I've been using it but the shop put some green stuff in it.
I have a 2005, V8, Phaeton with 181,000 miles. Also, my car overheated, got the coolant too hot warning, 270 on gauge, let it sit 5 minutes, no problem afterwards. Should the thermostat have been changed also?

One last issue with my 2000 B3000 3.0L. The leak seems to be on the left (passenger) side of the water pump very near where the bottom radiator hose connects to it. I can't find any loose bolts. It does not leak while driving the truck or soon after. It has to sit for several hours or overnight before it shows up. There are usually 3 or 4 wet spots where it drips from the water pump to the frame to the driveway. It is small enough that I only have to fill up my coolant tank every 1 or 2 months. Could this just be a small gasket leak? It's been happening for about a year or so I think. I replaced the radiator about 2 years ago. I've been expecting it to get worse or bust loose and have been checking it very often. I've never seen one not leak while running like this-has me puzzled.

So I parked on an incline last night for ~an hour or so, and suddenly my coolant light came on and my reservoir was completely empty. Sure enough, all the coolant had leaked out of the car. I am sure it's the water pump, but it doesn't seem to be a complete failed one because I picked up and filled my car's reservoir back up today and it hasn't leaked at all.
My guess is the pump isn't bolted on right and on the incline, the gasket is breaking it's seal, or some oil dripped down onto it when on the incline and the gasket swelled.
Nonetheless, my dealership is covering it on Friday, and they said they finally are making them with metal housings instead of plastic, and recalls should be going out soon (win for the MKVI crowd).

So my coolant system woes have continued! I recently replaced my thermostat ,thermostat housing, thermostat cover and all of the rings and gaskets. I finally stopped the leak on the driver side which seem to be the thermostat now about seven days later I am experiencing leaking on the passenger side. I walked out from work today and noticed I pool of coolant under the car. I can't tell exactly where it's coming from but it's coming from one of the components that runs off of the large belt. I snapped a few pics from the bottom of the car I don't think this is the actual component that's leaking. I think the leak is just falling off of it . I was wondering where the water pump is located.

I was driving my 2005 RX 330 (138k miles) North on I-75 through Atlanta in rush hour traffic when the car completely died in the left hand lane w/ no shoulder. GDOT stopped six lanes of traffic to push us up and over a couple of hundred yards to a right shoulder. It was determined that due to a coolant leak from the water pump the timing belt malfunctioned and shredded.
I had heard that the water pump should be replaced during the 90k maintenance when the timing belt is changed, but my water pump was not replaced according to my maintenance records. I understand from reading a couple of posts that this isn't always required but that they do check the water pump. Is this correct? And if so should they have noticed that there was a potential problem?

I have a 1996 Explorer with the 4.0 motor. Today coolant started running out between the Freon compressor and the block at the front left corner. I cant see behind the compressor. Compressor hose seems to be short and stiff so removal of the compressor is questionable? I look from the front and does not seem to be thermostat or temp sensors. It appears to be behind that, like the bottom of the intake manifold? I wonder if there is a known problem in this area or how to go about disassembly. Don't want to take off compressor and steering pump if the problem is intake manifold. Have a problem ? Where to start disassembly to look?

I have a 96 explorer that has recently developed a coolant leak. i was able to find the location of the leak, but i am puzzled by what is causing it. It is leaking on the back, passenger side of the engine, and while the truck is running it just squirts coolant out on and off...i am guessing it leaks when the thermostat opens. anyways, what is could be? i was thinking lower intake gasket, but i have never seen a lower gasket squirt like that!

I bought my 2008 JDM Prius a couple of weeks ago, at 84,500km. After a week, it started losing engine coolant. (Great start! Hope it's not a sign of things to come...) Fortunately, covered by a 3 month Dealer Warranty - hopefully. Yet to make the claim.
Anyway, went to the local Toyota Dealer to get some of the proper Toyota SSL (Super Long Life) Coolant to top it up. Got chatting with the Service Agent about Prius Service and what HSD Adjustments are possible (not many) and showed him my symptoms.

I have an 04 ford explorer, with severe coolant leakage. I am far from an expert but it seems like it's coming from the center engine block, but I can't get much access in to tell. What's going on?

I replaced the water pump on my 3.0 and now, 9 months later, there is a coolant leak from the front engine cover (timing chain cover). The leak has probably been there two months or so, but it was so small initially, it was difficult to locate. A google search seems to indicate that a leak from the timing cover is somewhat common on the 3.0.
When I was doing the job, I noticed that some of the water pump bolts also hold the front cover in place, which seems like a bad design because removing those bolts takes some of the compression off of the timing cover gasket. Now that I have this leak, I'm wondering if changing the water pump is related to the leak. And, yes, I did use thread sealant on the bolts as recommended in the genuine Ford shop manual.
So now, I'm curious. Noticed a leak from the timing cover relatively soon after replacing the water pump on 3.0?

92 PA Base ... Attempting to replace water pump. Is a hydraulic jack required to hold up the engine when removing the engine mount? The engine mount (passenger side front) is covering the right portion of the water pump. Although the engine mount has two holes for the remainder bolts of the water pump, there's no room to fit a ratchet or anything to remove the remaining two bolts. It appears the mount must be removed to replace the water pump. Is this so? How to correctly remove the engine mount.

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.

I have a 06 f250 that has a coolant leak in the front of the engine. It's was leaking about a month ago replaced the water pump it stopped. Then about 2 weeks later it started back up again. It only happens when the engine is cold. But once it warms up it starts leaking again. I am confused as all get out on this.

This is an update to my Heater Hose to Water Pump Failure post. As it turns out, the water/coolant pump seems to have failed at the same time as the heater hose. I think Ford secretly installed an internal time mechanism to deconstruct certain parts at the same time.
Anyway, in desperation I took the van to the local Ford dealer for an inspection. NOTE: I don't trust most of the locally owned small time shops and national franchises. Half of the time, they don't know what they are talking about.
They said the water pump is toast. And I already knew that! Then they said, because the water pump is attached to the front timing chain cover, they need to replace the gaskets there also, and also the oil pan is attached to the front chain cover, so that needs done, and then they said the radiator is also leaking. What!!!
Then they asked if I would be interested in buying a new or used vehicle. This tool works great. Mine happens to be a left hand fan. The tool is used with the handle on the left. This tool is used to hold Water Pump pulley stationary, while unbolting the fan assembly.
Tomorrow morning is when I finally replace the water pump. Not a lot of tool are needed, except for the stubborn fan clutch. Sockets: 8, 10, 13, 17, except a 22 mm open end wrench for the fan clutch.

I have a noise coming from the front of the engine. The noise stops once the the thermostat opens and the water pump starts circulating coolant.

1995 Ford Van E150. So I've been trying to solve my overheating problem for months now. One morning I walked out of my house and all of my coolants was on the street. I could not completely detect the source of the leak after running more coolant through it. I also checked the dip stick and coolant on the ground for any sign of oil/coolant mixing. I started by replacing the thermostat.
I did a more thorough inspection and found a crack at the bottom of the radiator that I replaced less than two years ago. I replaced the radiator again and while I had the belt, intake and fan disassembled I switched out the water pump as well. The old water pump was gunked and the gasket was almost completely worn off. The van is still overheating and spitting out coolant at a much higher rate. I'm guessing because of the new water pump. A friend said it could be the intake manifold because of where the steam was coming from the motor.

I replaced my water pump on my 2000 Excursion 7.3 about six months ago because it was leaking from the little hole underneath. Everything was fine until today I noticed a big stain on my driveway under the front of the truck. I took a look and the new pump is leaking. It seems to be coming from the the back of the water pump where it sits flush against the engine.
Could the gasket have deteriorated or cracked? I bough it from a local parts store called part source, so it should be under warranty. Any thoughts?

I've been working with my son to get a 92 Honda civic LX running. When finished, it was running fine except for the temp gauge always showing Hot. My son replace the Thermo sensor for the gauge but over tightened an snapped it off. I had to drill out the remaining piece and clean the threads to install another sensor. When we started the car, white smoke was pouring out of the exhaust and when rev'd, coolant came out. I think I may have drilled in too far and created a leak. How can I repair this?

I replaced a water pump on a customers 2013 5.0L truck this week. The bearing was totally shot and lost all the coolant. Truck only had 46000 miles on it, is this common?
