Ford - Explorer :: 2008 Limited 4.6L - Small Coolant Leak?
Mar 15, 2012
I've got a coolant leak on the drivers side of the radiator. I don't drive the vehicle that much because I use it primarily for towing in the good weather seasons. I drive it once a week unless we have snow than I drive it more.
I have seen small amounts of coolant (yellow/gold) in the snow when parked. It does not appear to be very much, but it does concern me.
Anyway, here is a link to some pictures : [URL]....
Where to look for this leak. I looked from the bottom and the top (without access to a lift) and I couldn't see anything revealing.

I'm having a little bit of trouble finding the cause of a minor problem on my 06 Explorer with the 4.0 V6 engine. When the engine is running cold at idle, it runs a bit rough and idle speed is high as well. When fully warm, the engine runs and idles fine. I hooked up a scan tool and there are no pending or stored codes. The live data looks ok except the long term fuel trim which is at about +10% on both banks during idle, indicating a lean condition. Short term fuel is right around zero. The MAF and TPS values seem to respond fine when applying steady throttle.
So I assume there must be a fairly small vacuum leak somewhere that the PCM is able to compensate for since the long term is only at 10. I didn't see anything obviously wrong, the vacuum lines look fine along the passenger side near the firewall. I sprayed a bit of throttle cleaner along the hoses, intake manifold and gasket area, but could not spot any vacuum leaks. Any other common areas to check for leaks on the 4.0 V6? Perhaps there is something I am missing?

After 150,000 miles, the radiator has developed a small leak. Question- do I have to remove the fan or can I just unbolt the shroud and push it back to slide the radiator out? I don't have that special wrench to spin off the clutch fan. 1997 Explorer 4.0 ....

I 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.

2003 Jetta Gli seems to have a very small coolant leak. The leak is small enough that I don't even notice a puddle on the ground the light on the dash told me it was low. It is the Vr6 motor. Also I don't know if this is the right forum for my car the title says 2004.5 Gli mine's an 03. If this is a big deal just let me know and I'll delete this post and go else where.

I've noticed the past few days that my car has been leaking a small amount of coolant. I've only had the car a month, and it has 1300 miles on it. I'm in Texas so it's been about 100 degrees every day.
There's been a few times that I've turned off the car and the fan has stayed on for a few minutes, so it must be getting pretty hot.
I'm assuming this little bit of coolant is just coming from the overflow, but I've never had a new car do this so I'm concerned that there's a problem. I checked the fill level, and it's a hair above the LOW line, so it's within range.

Changing my oil today, been awhile since I had the hood open for an inspection a year maybe about 5 - 6K miles
It's been about 2 years since the prior owner had it in for a service, I recall they had it in right before we purchased it in August 2008
I live in Miami Beach where it's HOT
I noticed the inverter coolant level is no longer at full It's hard to see where it's at, actually
It's not below low, and it seems to be at least up to the bottom of the double seam that wraps around the tank, but I can't see where it levels off behind the seam
Should I be concerned enough to take it in to the dealer and pay them to hunt around until they find a small leak, or is it normal to lose a small amount of coolant over the course of a couple years
Should I just buy their high priced Toyota Super Long Life Coolant and top off the extra 1/8-1/4" or so until it's at FULL?

Had a P2181 come up twice now... both on startup on a cool morning. Came on again this weekend. Monday morning I noticed a small coolant leak under the front of the car directly in line with the passenger headlight, but it only leaks if I park the car with the front down a slope. I parked uphill on Monday night and no leak in the morning, but I backed in facing downhill on Tuesday and had a small leak when I checked late last night.
So, last night I broke out the UV/black light -- G12 seems to fluoresce yellow'ish. I couldn't see much, so it is a small leak. There is some wetness on the bottom passenger side of the rad that's dripping over the back side of the front bumper/lip. No wetness around any other hoses, thermostat housing, temp sensor, turbo lines. But that's all from the top view. No time yet this week to get it up on stands to pull the bumper/splash shields for a closer look either.
I am little concerned tho as there's some wetness around the valve cover and when I pulled the oil cap my eyes suggested a bit of fluorescence under the cap and inside the valve cover. I'm a little worried oil and coolant may be meeting up somewhere... And to think... I was just in the process of getting geared up to do brakes and plugs before getting a modest tune (stage 1).

Quick question, my 2007 Santa Fe with 3.3 has developed a small coolant leak. Every so often, I see a few drops on the garage floor and every 6 months or so I need to fill the reservoir with new coolant. So I took it in last Friday at a Hyundai dealership and he said that I need a new head gasket.
So my question is, is that correct? I did a search and most say that if you need a new head gasket, coolant would have leaked into the engine and oil.
When I changed the oil back in June, I don't recall seeing any foam or-or any indication that something is wrong with the oil. Even yesterday, I open up the oil cap and pull the dipstick, every looks normal. I assumed that not all head gasket problems lead to coolant in the oil?

The last couple of days I thought I smelled antifreeze and I had to add about a pint of coolant to the reservoir. So I looked all around today and can't see anything leaking. Nothing on the floor. I suspected the water pump but looked pretty dry from what I could see. Thing is if its the pump, its still under warranty for a few months and 7,000 miles so want to find that pretty quick. Radiator is fairly new also from hitting a coon. Any tips? Not sure if a pressure test would detect a small or intermittent leak in the pump though.

My 2004 just developed a coolant leak. The past couple times I've moved the car, there's been a small pink puddle under where the engine was. The leak seems to be coming from a weep hole positioned between the two bolts of the lower engine mount. The hole is circled in red in both pics.

I have a factory plastic bedliner in my 05 F150 with the 8ft bed. The tie downs in the front of the bed have a small gap that allows water to leak under the bedliner. I have tried using silicone caulk around the seam but the flexing of the liner makes it come unglued.
How to keep the water from getting under? The water that makes its way through the seam drains out of the factory holes in the front of the bed but I still worry about the moisture under there causing rust.

Long story short, I have a small vacuum leak in the 4wd system. I disconnected the lines going to the hubs to prevent grinding them to pieces as they are brand new. This, of course lock the front hubs in and disengages the X-fer case in 2wd.
It is not engaging in 4wd unless I select it, so I don't imagine it hurting anything in the X-fer case or anything. Other than the extra rolling mass, is this okay to operate at until I resolve my vacuum issue, provided I close all openings and places for trash to get in?

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.

I have a 04' RX 330 with 92k. It has small radiator leak. If you are standing in front of the car and look below the fan on the left side of the radiator you can see a small amount of red fluid that has leaked out of the radiator. However, the leak isn't big enough that I ever have to add coolant I just top it off when I get the oil changed. Also it doesn't puddle on the pavement when parked.
The only thing I really notice is that my windows tend fog abit easier now so I assuming the moisture must be making its way into the ventalation somehow. My mechanic said its about a $700 repair. My question should I fix it and is $700 reasonable. Also I've never had the timing belt replaced would it make since do have this done at the same time as the radiator. How long will it take before it becomes a major problem instead of a minor annoyance?

I 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?

I 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?

I've got a 2001 Explorer 4.0L with around 160,000 miles on it. Just noticed this morning it has developed a coolant leak. It's dripping off the rear of the oil pan and appears to be coming from the passenger side somewhere above the oil filter. Without tearing a bunch of stuff apart, I can't really see for sure where its coming from. Are there any common issues with this? I'm hoping its not a head gasket...

Son in law just bought a 2002 Explorer with the 4.0. Looks in pretty good shape and overall I don't think he got a bad deal. However....after a test drive I noticed an antifreeze smell. Got to poking around and it appears to be leaking directly below the thermostat housing and that whole manifold for lack of a better word. It's a bugger to get in there and really see what's leaking...doesn't appear to be any hoses but given the angle can't be really sure. I'm new to the Explorer and the 4.0. Is this anything peculiar to the Explorer/4.0? A known part problem? Something far worse?

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?
