coolant leak

Hello all, Unfortunately my first post here is on the heels of bad news. Bottom line up front: independent auto shop diagnosed my ‘17 Explorer Sport as having a leaking head gasket, with no overheating indications preceding. Background: Bought this ‘17 Sport in 2023 at 94,000 miles, and have...

My trusty 94 is leaking coolant from here: That pick is looking up through the passenger wheel well. That black unit is wet at the low point from coolant. Anyone know what I'm looking at there? Thanks...

Beginner mechanic here just bought a 96 5.0 about two weeks ago and have been trying to fix it up. Didn’t do too great of a job inspecting it before I bought it. When I brought it home I realized the coolant system was extremely gunked up and was leaking down from somewhere that I can’t see. It...

Yesterday I drove around 5-6 miles and when i stopped I noticed white smoke/steam coming from under my hood so I checked and found a puddle of coolant on my manifold the vehicle has never run hot I checked my oil to see if there was coolant in my oil but there isn’t I can’t find any visible...

I have a 2012 Ford Explorer base model v6. My coolant leaks right above my driver side muffler and it smells bad. I’ve brought it to a shop they said was fine but it’s just progressively getting worse. I need help trying to find either the full lines to replace them or if anyone knows any tricks...

I just replaced my Thermostat . The engine is running 20 degrees hotter. Now my thermostat housing gaskets are leaking. This diagram calls for parts 7 and 8. I have not found these parts in the engine cooing section of the service manual. Auto zone was able to sell me part number 7 and orlies...

Hi everyone. Over the past few months I noticed a very small amount off coolant on my driveway when the vehicle cools down after a long drive. It was never a concerning amount and due to the vehicles age I was not too concerned. I monitored the reservoir and it never reached a low level...

I have a '98 Explorer, the engine and radiator were replaced in Dec. 2014 by my local Ford dealer. Since then it has been burning through antifreeze - and by 'burning through', I mean I put between 6-8 gallons in it per year since it was replaced, and on par to do the same this year. There are...

And now mine is leaking. 2010 Eddie Bauer, 4.0 V6, 4WD, Auto. Purchased in late March. Appears that the dealer replaced the radiator, Thermostat housing, and upper radiator hose. There has been a smell since day 1 and I need to top off the coolant every other week or so. No sign of a leak...

Greetings, Looking for help on where my coolant is going to... Have an 02 Explorer with the 4.0 SOHC engine, high miles (286K). Coolant has been disappearing from the system at about 16+ ounces a week but can't find where it is going, have checked the following: Pressure tested the system, It...

Thanks for any info or tips! I have a 2001 Explorer Sport Trac 4x4 Recently my coolant temp sensor went bad and before I could fix it I developed a leak. I've since replaced the sensor and thermostat. The weird thing is some days I get just drips other days I lose quite a bit of coolant...

I'm looking for a timing cover for my 91 ford explorer sport v6 I had a coolant leakage through it but have currently stopped it for right now with some my stop leak. I would just like to know where the best place to find one would be so I could have one just in case.

hi, I’m new here. I have a 03 Ford Explorer. I have a crack at the Y or T (see in picture) I can’t fint the part to replace it. I tryed to seal it just to get by until I could find the part. But now one of the hoses fell out of the Y or T. It’s the hose by the arrow. It’s easy to get to I...

I put in a new radiator yesterday. No drips from front end but there is a drip or leak from underneath passenger seat. It’s very faint but you can see where the snow is stained green. What is doing there ? Do coolant lines run that far back ? Thanks.

2010 Explorer XLT 4x4, V6 Hi all, I've had this Explorer for a few months. It was a well-maintained fleet vehicle, and I've had no major issues with it. I've been monitoring a tiny coolant leak from the thermo housing. It will only get worse and I will replace it eventually. So I topped off...

Original motor in this well-maintained vehicle with a lot of miles. Noticed slight overheating occasionally over the last year or so; gauge would fluctuate up very fast and then down in a few seconds, right after getting on the road. Coolant was low, so I topped it off and the problem...

2000 rwd with 4.0 soho with ac. i have a coolant leak which appears to be coming from the right side (pass) of the pump. I just can’t get a good look at it to really verify it. I am thinking to pull off the alternator, alt bracket, and tensioner just to verify it. May put everything back on...

In the last year my 91 Ex has been steadily loosing coolant, causing it to overheat. When I first noticed this it was a minor amount, but progressively got worse. Then I noticed that even when the coolant levels were topped off, it would still overheat a little on hills. It's kind of hard to...

I have a 92 explorer. It overheated yesterday after driving around a hilly park at slow speeds for about a half hour. I cooked it down and put water and what coolant I had in it. Now idling in the driveway it starts to heat up after 5 minutes and coolant starts overflowing from the fill tank...

I have a 2000 Ford Explorer XLS, 4.0L OHV engine with 188k miles. ****Long story starts here, skip to "Short Story Starts here" for current issue, or "Really Short Story Starts here" if you are really, really impatient!!******* Three or four weeks ago it started losing coolant...

Greetings, My 08 Ltd 4.6 radiator has had it. I am pretty sure the car was in an accident of some sort before I got it (with 60k) as there is some misalignment of some front end body parts. I *think* it is the original rad as it is stamped 10-17-2007 on the mfr date code. That said, the...

Stock 2007 4.0 L V-6 Explorer Hello: Yesterday my wife drove our X about 30 miles into the city and back to where I work. It was idling for about 15 minutes maybe. When she began to drive away, a co-worker noticed water/coolant starting to pour from under the engine. I was able to look at it...

Alright guys, I have been losing about 1 gallon of coolant a month, very slow leak. I am now losing about a gallon a week.....I have looked everywhere, changed a few hoses. One thing I noticed is that coolant seems to be pooling ON TOP of the engine. Here is a couple pics.....where the heck...

So I've know that I had a few minor leaks since I got my Explorer last year. I just recently replaced my valve cover gaskets and cleaned up that minor oil leak. Now I have a coolant leak that seems to be getting worse. I had thought it was this hose here This is on the bottom driver side of the...

*****UPDATE****** So I was actually able to fix the problem that I was having with the dome lights remaining on even after the doors were closed after an extended period of time. The problem was the door ajar switch located in the driver door. I ordered the part from AMAZON and for those who...

My 08 Limited lost most of the water and went into self protect mode which scared the crap out of my son. I didn't know what is was until I read the owners manual. The stupid thing has no low coolant warning. The leak was hard to find because the leakage runs down the bottom of the hose then...

A family member had noticed that it looked wet in a specifc part of my engine while we were taking a look and refilling the coolant. I had noticed something similar a while back, but I was foolish and thought it was just rain. I think that was a mistake :P I use 50/50 coolant and the level...

New to the forum. I live up North and am trying my best to winterize my car before the snow starts. For a year now, I have noticed that my coolant level drops in my explorer very quickly. Last winter I had to fill it up with one entire jug of radiator fluid every 3-4 weeks. A year later, my...

Hi, I don't have much time to post, but here is my recent discovery on the leaking/exploding plastic thermostat housing on the V6 Explorers from approximately 2002 until approx 2010. A few comments: Using my VIN for an 06 XLT w/ V6, they've offered the AL2Z-8575-B ( AKA motorcraft RT-1220 ) It...

Hi guys! Yesterday I was changing my pitman arm seals and noticed a coolant tripping near oli filter. Checked the heater core and it was dry and looked normal. No sign of coolant. What should I check more? Marek

I have searched and read many posts and Youtube videos regarding this housing, common issues of the leak, and removal procedures... HOWEVER, I can not find a video with the proper steps (even the Ben Grosser link) that truly identifies the set up that I have. I will try to add pictures soon...

I have a 1998 explorer V8 that is leaking coolant. I replaced the waterpump last night because it appeared to be where the leak was coming from. After replacement I am still leaking and now notice coolant around the timing chain cover gasket (I replaced this 5 years ago) Is there anything above...

New to posting here but been looking around on here for a few years now. My truck is a 99 Explorer Eddie Bauer with the 5.0 V8. I have a coolant leak coming from my engine. The mechanics at midas told me its coming from the header and that i would need to replace the whole header not just the...

I can't figure this out. Can you? At the very rear of the vehicle on my 2007 Explorer on the driver's side there appear to be 2 coolant lines. It appears as they are both leaking. Has anyone had this happen to them? Why are they there in the first place? At first glance it appeared the...

I have a 2005 V6 Explorer. Yesterday I gunned the engine to get around someone on the highway and all of a sudden I smelled coolant and saw a leaking trail coming from behind my car as I drove down the highway. I pulled over and popped the hood and there was coolant everywhere and I saw that...

Hi im new here, and pretty much a newbie at learning about cars. But I just had a coolant leak pop out of no where. So let me being. I drove my 97' Ford explorer 5.0L V8 2 hours up to my dads house. The next day we were changing my oil where we noticed coolant dripping very slowly from the...

I'm getting ready to replace the lower intake manifold gaskets on a 1997 Mouny with the 5.0 V8 due to leaking coolant in the front driver's side. It's right at the corner, and around the most forward bolt that also holds the coil pack. Anything I should watch for? I didn't see anything in the...

I recently noticed that my coolant reservoir was completely empty so I took a trip to Autozone and got a jug of coolant and filled the reservoir to the cold fill line. About a week later I popped the hood to discover again that my coolant reservoir was empty. Upon further investigation with a...

I have a 2002 Explorer XLT 4.0 and the engine coolant overflow hose developed a leak from rubbing against a pulley (not the skinny little over flow tube, but a fatter molded radiator hose, goes from bottom of overflow reservoir to the low end of radiator)... but that's not the problem.... I...
