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?
View 2 RepliesWe have a 2006 Civic and there appears to be a coolant leak coming from the engine block above the started motor, so it is hard to see clearly. The kids are about to leave for Atlanta (from Iowa) and I am concerned that this could be a crack in the block based on some on-line discussion. Is it risky to send the kids on a 1000 mile trip without fixing?
View 6 RepliesI replaced my Radiator, Upper and Lower Hoses, Thermostat and the thermostat gasket yesterday. I am leaking coolant from the thermostat though, It's coming from the seal between the housing and the block. The gasket was brand new and seemed to fit fine. I don't see any damage around where the seal is made..
Going to run and get a new gasket when the store opens.
My 2009 Vue developed a coolant leak into the oil at 130k km. I had to have replaced. GM has a technical note about this exact problem with the recommended fix: Engine Replacement. The coolant was leaking into the oil at the water pump.
The Statement from the dealership states that there was a crack in the block near the water pump. The dealership was good but a block should not break like this. Is this a design defect with the block, and if so is their a class action already started?
I was searching for an oil leak forever. In my search for the leak I resealed my hpop, redid oilcooler rings and last week had a friend pull my motor to redo the pan gasket. The leaks were almost down to where I thought we had them beat. Now in the last couple days I'm losing coolant and oil....bad. there is oil on the ground mostly from the cross member. Question is did my oil cooler fix not take? I have read that a nicked of ring can cause this.
View 11 RepliesWhile servicing the bosses 121k 6.0, I noticed the coolant resevoir empty. It took 1 1/2 gallons to bring to proper level. Returning under truck to install drain plug, I noticed coolant coming from rear of the engine(right side). And of course Ford has changed the cooling system cap, so I wasn't able to pressure test it to pinpoint the leak. Started the engine and seen coolant coming from the left rear as well. I've been reading here to see what others have been seeing, (EGR cooler, head gaskets). With all the heat shields,not much room to look.
After work I did go and buy the adapter to test the cooling system. With any luck I will be able to see leak better.
I have an '04 Ranger Edge 3.0 with a severe coolant leak. It appears to be coming from the area where the head/water pump housing meet. I have been told I've lost the seal behind the pump on the timing cover. Is there any way to know for sure? Will I be able to tell, once the pump is out that it isn't coming from the head side? Are there any "special" instructions for re-sealing after replacing pump?
View 6 RepliesSo broke down today and have no tools, in a city I don't live in. Huge coolant leak behind the block on the passenger side. Luckily we broke down right at a mechanics shop. They need to take off the manifold to get to the rusted out metal piping in back.
I am new to the V10. Looking for information on what could be leaking back there? I know I could do this myself but I need to know what parts I might be dealing with first. And its tight quarters back there.
Seen a coolant leak near the back of the block? I did an oil change and noticed coolant on the bell housing.
View 7 RepliesI 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!

Any way to fix it without pulling the cover?
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).
116000 miles 2005 sport trac, antifreeze leak possibly coming from the engine. I haven't been able to pinpoint the leak.
View 4 RepliesI have a small coolant leak coming from the passenger side near the back of the engine that forms a spot about the size of a dinner plate if it sits for a few days.
One thing I noticed is if I turn off the AC selector switch when I park I will get the drip but if I leave the switch on MAX AC when I shut the truck off I do not get any leaking.
It is definitely coolant and not just the condensation from use of the AC. If I haven't used the truck for a few days or if I have run it with the AC off I will get the drips.
If I run with the AC on and leave the switch in the on position when I shut the truck off it won't leak. I have tried to locate it from looking above and below but can't determine where it is coming from.
Just did a tear out and rebuild, installed motor, filled with water. Water is leaking out of the back of the engine somewhere. Leaking as if it were coming out of a 1/4" diameter hole. 1997 V4.6L F150. I guess I have to pull it no matter what. Cracked block? Freeze plugs were all new and installed by machine shop. Initial reason for pulling was water in cylinders and I assumed blow head gasket.
View 1 RepliesI've got a 1997 Dogde Ram 1500 Pickup. It's got a major coolant leak that seems to be coming right from the middle of the front of the engine. I can't see where it's coming from. I changed the thermostat and the water pump, but it seems to be even behind that. There is a rubber hose that comes off the water pump and disappears between the two banks. I can only see a tiny end of it, where it goes. It looks like getting to that would involve taking off the whole intake manifold. If that's the case, I might as well total the truck. I dunno...

View 3 RepliesI have an 04 Excursion with a 6.0PSD. I am currently experiencing a coolant leak, not very bad at the moment but I would like to fix it. The coolant is running down the back right side of the engine and I can see coolant pooling on the pan on top of the motor, specifically the right side. I can see some moisture on the front of the engine but it is below the top of the engine and I do not think this would be the cause since coolant won't flow up hill. I can't see or smell any coolant flowing when the engine is running but see it at idle and when parked.
View 5 RepliesI have 2010 explorer. I have to add almost 200 ml of coolant in my reservoir every week. there is no sign of a leak from anywhere even at thermostat manifold as well. but one question, when the car is running for at least 1 hour, the coolant level at reservoir shall be around FULL HOT Level and when car cools down overnight, it should be at around FULL COLD LEVEL. is it right? if yes, then my level remains little more than FULL COLD when the car is hot and when it cools over night, level goes little down than FULL COLD. like this every week I have to add almost 200 ml of coolant. radiator CAP is okay and I replaced it few months back. no apparent sign of leak. any clue what can be reason?
View 2 Replies2004 Jetta GLI 2.8 ... Tonight I started getting a coolant leak somewhere on passenger side. There is also a loud noticeable ticking coming from that area but it is NOT the engine. Slow steady tick, just to the left of engine (when looking head on). Car also began to overheat. Coolant reservoir is full, too flow to be honest, but I don't see any leaks from there. No check engine light is on. Car does NOT leak coolant when off. Only when running and putting load on engine. At idle I cannot see any leakage. Thoughts? I'm thinking perhaps water pump? 87k on the car. Original pump from what I can tell. Bought the car a week ago.
View 24 RepliesI looked at a 99 with a 5.0 and noticed a puddle on the driver side, a little below and inboard of the power steering pump but outboard of the water pump. The puddle was higher than the water pump weep hole and it was in a racetrack oval shape. I was unable to see where the leak originated and I couldn't tell exactly what part/housing the puddle was sitting on. Obviously, the leak had originated from above.
I don't think it was coming from the upper radiator hose as I remember the upper radiator hose being more on the passenger side and I don't recall any heater hoses in the area. The only things that came to mind as the potential leak source were the intake manifold and the sensors on it. Are the 5.0 intakes prone to coolant leaks? Other than hoses, what else would be leaking coolant on the driver side?
