View 1 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.
Small coolant leak on drivers side when car sits over night. Car has 3.5L engine with 118000 miles. Purchased used a few months ago. Just started leaking a week or so ago. Dash came on with low coolant level. Added a small amount of coolant ( at the add coolant level line) and then started noticing small amounts of coolant under car in the mornings.
View 3 RepliesMy Toyota Camry (2000) has recently developed a small leak on the front passenger side of the car. The water seems to be coming in from the bottom of the front door about two inches from the door hinges since I can clearly see a water stain there. My mechanic has tried to locate the leak and he seems to think that it may be the windshield. He claims that he hosed it down and he thinks it is the windshield. To repair it he suggested that I will have to re install the windshield. How can I be sure of this?
View 3 Replies2002 Camry 4 cyl was leaking a small bit of oil on the rear passenger side of the valve cover - about directly behind where the timing chain is. I replaced the valve cover today, but noticed that there is still a small amount of oil leaking at the same spot. Is this a common problem with the '02 Camry? Or perhaps I have a valve cover problem?
View 2 RepliesToday I did a oil change (70k). While under the car I notice a small leak from the back side of the engine. When I got home, I had the chance to remove the engine cover to investigate and clean the engine up a bit.
I found that the bolts in the rear of the valve cover had a little puddle of oil around them. I took a T-30 torque bit and was able to get a least a full turn on the rear bolts and about half turn on the middle ones. Fronts were about a quarter turn. Check your valve cover bolts.
Coolant leak on the passenger side. Leaking enough to leave a puddle on the floor. This is a 2000.
The water pump is good. Weep hole is dry. All of the radiator hoses look good.
The traditional intake manifold gasket looks fine, even though that isn't really a suspect here.
Looking up from the bottom, coolant is dripping from what appears to be a lower motor mount right next to the oil pan. Also, the area around the crankshaft pulley looks wet.
What should I look for? Could it be a leak from the engine oil cooler? Are there hoses on the back side of the engine? It doesn't look like it's anything simple.
I did a search but found nothing on a coolant leak. My 07 (57K) has developed a leak on the passengers side of the engine. Not sure if its the water pump (not making noise) or the themostat housing as a mechanic who took a very quick look at it suggested. How hard it is to get to the thermostat housing? Anything else have to come off? I don't have a FSM.
View 14 RepliesI've got an '04 1.8t jetta with 158k on the clock. Recently noticed I have a coolant leak on the passenger side of the car. Started the car in my driveway and looked for drips and found coolant collecting in the front valence right underneath the intercooler. Took a look from the top and noticed the hose going into the bottom of the part shown in the picture is leaking like a sieve. It's the metal canister-type thing on the passenger side right next to the radiator. What part this is? And where I can get a new hose that connects to the bottom of it?
View 11 RepliesSo 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.
View 5 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.
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!
View 3 RepliesI 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.

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?
Alright, after finally fixing my 4X4 issues, now I have a coolant leak. It's on the passenger side, just above the exhaust downpipe. I can't find any leaks in the hoses, and as far as I can see it looks like it's coming out of the back of the head and running down the back of the block. The odd thing is there's no oil in it, and no coolant in my oil (which obviously is a good thing), but I don't want it to get to that point of it is getting worse. Heat works fine, and it isn't overheating, only losing maybe a gallon a month. At some point the ford gold stuff was flushed and it has the compatible green, that is the only thing I can tell is not stock. I don't want to tear it down if I don't absolutely have to.
View 7 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 RepliesMy 2003 GTI 24V VR6 is leaking coolant pretty quickly from the passenger side of the engine compartment. I have a new water pump in hand. If I'm replacing the water pump, would it be smart to go ahead and order a thermostat and metal crack-pipe to replace at the same time that I'm having the water pump installed? I'd hate to get the water pump installed, and find out that the leak is at the crack pipe.
View 3 RepliesI 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...?
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.
View 6 RepliesGot a leak that just developed after a long trip. It's not big, but I am not sure what it could be? I see in front of the rad is a smaller looking rad, and in front of that behind the grill in the bumper is an even smaller radiator-radiator-looking box. I see two small hoses coming out of it, down under the rads but above that metal brace. Does that hold coolant? Or one of the other radiators?
View 5 Replies2003 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.
