Ford - Explorer :: 2010 V6 - Coolant Leak - Level Goes Little Down?
Apr 19, 2016
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?

My friend bartered for a '99 F250, 2wd/auto, 4 door, 7.3, 258k miles.
It had reportedly sat for one year, though the expired registration sticker and other things point to it sitting for two.
It ran low on oil, sputtered and died. Oil in the degas tank. Filled to oil to mid way on the hatch marks on the dip stick.
I drove it 25 miles to my house, and the oil level is not reading on the dip stick.
The sludgy fluid level in the degas tank is unchanged. Where is the fluid going?
I will refill the oil to see just how much it lost in the 25 miles if it important to someone, but I prefer to not waste the oil.
My first plan is to remove, inspect and replace the oil cooler o-rings. Even though the dealership charged him for this, I don't trust that they did it right. I think it is the easiest and mostly likely place for oil getting into the coolant.
It does have a really long crank before there is enough low pressure oil for it to start. At the moment I think this is a separate issue.
The dealership also charged him for a replacement injector. No idea if they replaced the cup or not.

I have a 2002 Ford Explorer and I am still trying to figure out why the coolant will overflow in the radiator reserve tank. I put in a new thermostat and a new cap to the overflow tank. When the tank is cold, sat over night, I put in new anti-freeze to the cold coolant line. Then I start up the explorer and let it run for a while. The temp gauge goes up, then drops a tad and cold air comes out of the vents.
After I rev up the engine, I see the coolant level starts to rise in the overflow tank, then it goes to the top and starts to leak out. This takes a while being the thermostat has not kicked in to suck the fluid in. Before this happens, the heater core lines are luke warm. After the tank overflows, the remaining gets sucked into the engine and I get nice warm heat. What causes this. I had the test done to see if the head gasket is bad. The test was negative.

Have a small coolant leak. The level is dropping and I can smell it but I cant find it. The radiator was new at 100K miles and the heater core is bypassed. No evidence on or near the hoses, water pump or radiator. Getting ready to replace all the hoses because they are overdue but I would like to find the leak(s) first.

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?

The "stop!" check level! alarm sounded as I was parked last evening...
Looked under car and a gigantic pool of coolant flooded under my car.
Where to look under the hood for loose or broken clamps or hoses that may be the culprit. Which hoses (color?) are the ones to check?

Just noticed my level is about an inch below the full mark, it was fine at the last oil change, no leaks that I can see....nothing on the ground.

I have a '98 Honda Civic with 230K miles on it. Last month, I suddenly saw few drops of coolant on my garage floor. I opened the hood and saw coolant splashed over the engine. I opened the coolant reservoir and it was empty. Surprisingly, the car never overheated and neither did the temp needle go up. I took the car to the mechanic (Honda shop) and they said that the radiator is leaking. I replaced the radiator and after driving for couple of weeks, the same issue re-occurred.
The coolant ran low in the reservoir and there was coolant splash over the engine. I took the car back to the shop and they said that the hose was not properly installed. They fixed it and said there is no sign of leak. I have been driving for a week now and check the coolant routinely. I have noticed that the coolant level has again dropped significantly. But, after the last fix, I do not see any visible sign of leak. There is no evidence of coolant anywhere under the hood. I am not sure if there is something else going on now. Is there something else I should check?

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'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 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 used to have a 1999 Mercury Mountaineer 5.0. Loved the truck but sold it because I didn't have a place to store it.
So I bought a 2000 E.B. Explorer! I love it thus far, I was doing a tune-up and now I hate it. I was changing the spark plugs and one of the spark plugs had a lot of rust around it. As I was chipping the rust away so I could get a socket around it coolant started to come out right below the spark plug
I have attached pictures too.
I don't know what this could be. I have done my research, anything from the lower intake manifold gasket to a cracked head. Need info about this type of leak? its no where near any gaskets, I have a friend that says I could have hit a coolant chamber but I wasn't banging hard at all.

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).

2007, 4.0L, Explorer, 113,000 mi. Week ago noticed coolant expansion tank empty while hot and cold. Looked inside ex. tank and looked like it had not seen any action in a while. Looked inside radiator and coolant level was about 1 inch to 1.5 inches below bottom of rad. cap would be...approx. level with rad. seam, where black plastic top of rad. attaches to metal portion of rad. I filled expan. tank to "cold fill" line. Kept an eye on it while doing light, around town driving. The expan. tank level (cold-fill) didn't change.
Friday, my wife returned from work (30 mi., interstate drive). After being parked for 45 mins, went out to find fluid puddle at very front of car. Expansion tank was empty. Looked in radiator, and it was about one inch to inch and a half below bottom of rad cap...about level with rad seam, where the black plastic top is attached to metal. I topped off the rad. this time, along with filling expan. tank to cold-fill line. Turn car on, and after warming up coolant starting coming out from what appeared to be the seam at the top of the rad., where the black plastic portion meets the metal part of the rad.

The oil cooler mounted above the oil filter on my 2002 Explorer 4.0L V6 has a major coolant leak on one of the external line/hose bib elbow. I've googled Explorer oil coolers and I've searched this forum with no luck. Can you bypass it without any problems mechanically or electronically (throwing error codes)? I have already purchased a new cooler and the lower oil cooler line. I'm just wondering if I should return the parts and bypass it. If I go through the replacement, I noticed the cooler is mounted by a pass through threaded tube with a hex head molded into it for fastening/loosening purposes. What size hex head socket it is?

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?

On Sunday I'm driving to the store my LOW COOLANT light goes on. So I buy some coolant. I get home let the car cool off and check my radiator, it is full. My coolant recovery tank is also at the proper level.
Been three days already checked levels again and I'm not losing any coolant.
What the car is NOT doing:
1. Not losing fluid
2. Not running hot
I'm thinking coolant level sensor?

I noticed yesterday while driving the RX (not my daily driver) that when I turned on the A/C to bi-level (chest & feet) it only blew cold air at the chest level while at the feet level it was warm air. If I remember correctly from the past that the feet got cold too so I tried it with the vents only at the feet, still warm air. I even checked to make sure that I didn't have it on bi-level with defroster in use.
