coolant

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...

Went offroading a few days ago and just noticed some red fluid frozen underneath my radiator and on the ground. I'm no mechanic and i'm not sure what to do. Can't seem to post pictures, but the two hoses going into my radiator look pretty wet. Also my coolant seems stupid low so i'm getting some...

Hi, Not seeing any traffic on the original posting I'd made, I'm cross posting to this tech section for better exposure to help others who've suffered from plastic cooling system parts. Here is my recent discovery on the leaking/exploding plastic thermostat housing onst, but the V6 Explorers...

I have a '94 Navajo w/ stock 4.0L V6. I have a serious coolant leak that I suspect is coming from the lower intake manifold and hopefully not a corroded or cracked one. The vehicle was dry until I filled up the radiator so there is no extra pressure on the system and you can see where the water...

Hello all i am a first time ford owner. Had to get something safer for the family and this was beat up outside but sposta be ok mechanically. Plus the price was in my very small budget. So lets begin 2002 explorer high miles i bought it today ... fellas crazy ex kicked and stabbed it repeatedly...

I am having an issue with a coolant leak on my 1996 explorer v6 4.0 that seems to be coming from behind the thermostat housing. It is not leaking out of where the metal hose thing bolts into the rest of the housing, when I squeeze my radiator hoses I can see coolant coming from a small crevice...

There is a coolant leak that mainly seems to be spouting from what looks like some sort of distributor right above the water pump. It isn't a steady leak though. There are times when the vehicle is idling and there may be a drip here and there but after just a little bit of driving the coolant...

Hey guys, Blake here. SO here's the new issue with the Exploder. For some apparent reason, I am losing coolant all the time, but it's not usually in the ground, it's on the underside of the engine. I'm talking like a gallon every other day. I just recently installed my 3rd thermostat...

Hi all, 2003 Ford Explorer XLT 4.0L SOHC V6 Right now my left side valve cover gasket is seeping oil. I heard this can leak onto the exhaust manifold and cause a fire so replacing this is fairly urgent to me. Also, the fitting that the PCV valve screws into appears to not have any...

Howdy, I have a lot of coolant consumption. I have to fill up my overflow tank every month with fresh 50/50 because it just disappears. Surprisingly enough, I NEVER overheat. I drove 4 hours a couple weeks ago to this restaurant I wanted to take the old lady to and the truck ran great...

Hi All! I have a 1995 Ford Explorer ltd. I'm wondering if anyone has used R134a refrigerant with stop leak. Pros? Cons? Thanks in advance!

I'm growing a little upset trying to figure out a clear answer to doing a radiator flush. I've posted this before but I just can't get the thoroughness that a newcomer needs to do this. Although I am mechanically inclined and determined to get stuff done, I must stress the fact that I started...

I have a bad mix of water and coolant in my system due to an overheating problem I had about 3 weeks ago. My system is probably 80% water and 20% coolant. I want to flush it all and start from scratch. I have 1 gallon of pure coolant, 1 gallon of distilled water, and 1 gallon of 50/50...

I have 2004 4.0 SOHC. I am getting coolant in the oil. I had the head gaskets changed. Has good compression, did a cylinder leak down test which was good and I am still losing coolant with some milky substance on oil cap. My question is: Has anyone heard of bad engine oil cooler? p.s...

I have coolant overflowing out of the overflow reservoir cap. I just bought this 1991 Explorer and seemed to be doing that already. I did a coolant flush, Blue Devil head gasket seal, and replaced the thermostat. The aftermarket gauge temp stays cold or reaches maybe 160 on occasion. I don't...

Guys, I need your help. My good friend, who isn't very mechanically inclined has a leak on his explorer's lower radiator hose area. I'm trying to get him back on the road ASAP, and need help diagnosing by this video what is going on. It look to me that the hose is leaking near the right (I the...

Thank you for your response seems the voltage issue is the least of my problems now. Yes I went to pep boys to have my coolant system flushes and they wouldn't touch it due to the antifreeze looking like "chocolate milk", and said possibly have a blown head gasket which I don't see very likely...

I have a 2006 Explorer 4.0 v6 XLT 4wd with 144,000. Recently when starting the engine and driving a short distance the temperature gage runs all the way up to hot and the temperature light comes on. The gage will then go down to the normal range and the light goes off. Doesn't matter if the ac...

Okay so my 2006 explorer v6 xlt was fine. My dad hit a deer a while back when it was his but all that's been replaced except he said my radiator was cracked so keep up with your coolant every month or two. So I've been driving it around fine, no problems. Even some light to heavy mudding but...

Ever since I've had my 1997 explorer, I've had issues with adding radiator fluid. After I flushed it and added new fluid, I noticed that the reservoir was soon empty after a day or so. I first thought that I maybe didn't put enough fluid in but I figured out that it started to leak at the...

Hey everyone, I have a 2008 2 wheel drive with 4.0 V6. there is a "hot coolant" smell under the hood while engine is running. no smell inside cab. does not loose coolant, even got my local shop to pressure it up, even he said it smells like coolant on a hot engine, however cant seem to find any...

My concern: I see fresh coolant "seeping" from the upper transmission cooler line going into the radiator. From everything I read on here, the ATF pressure should be high enough that if the radiator tank (or gasket?) were to break the barrier between coolant and ATF lines that ATF would seep...

Hey guys, so I just published my latest How-to video on checking the coolant freezing temp. It just hit below freezing in the NE so I figured this would save some people headaches from improper coolant:water ratios. Let me know what you think! If you like the video, hit the "thumbs-up"...

Hi folk, Looking for a little help tracking down a coolant leak on my 1998 ford explorer 4.0L. The coolant system seems straight forward on the car but just can't track it down. It seems that the leak is coming from somewhere in the area of the starter maybe just above the drivers side engine...

So as the title says, the head gasket let go on my 96 Ranger 4.0 OHV @ 163,000 kms. It was an external leak on the passenger side. Pissed coolant all over the ground and was running hot - but not quite at "H", and I limped it home. Since a pricey repair is a questionable investment at this...

Hey everyone thanks for taking the time to read this post. My X is leaking coolant once again. First it was the radiator and one of the hoses, they were replaced along with the thermostat about a month ago. A new leak started a few days ago, it seems to be coming from the drivers side, right...

Thanks for reading this, my Ohv X is leaking coolant pretty bad right now. I've had this problem for about 8 months now but never this bad. Whenever I turn the truck off it dumps coolant, it doesn't overheat though, the temperature gauge stays halfway. I always thought I just had to get air out...

Hi I'm max I'm new here. I have an 02' explorer XLT 4.6L that I purchased from a lady almost a year ago. I bought it with a bad coolant leak. I had that fixed there was a crack in the intake manifold (very common). I purchased the new IM at o'rileys and haven't had any problems with my explorer...

Hey guys, I have been a member since Jan 2012 and have gotten alot of good info from all of your post. But now I have a problem that I can't seem to find any answers. I have a 2001 Explorer Sport with a 4.0. That is pushing coolant into the expansion tank until it overflows. In the morning I...

Hi all, New to the forum after some lurking but I am not able to to find what I am looking for this time with searches. I know about the issues with the radiator in the 06 explorer. I have an 06 4.6L 8 cyl. It's new to me since last month. I bought it with an extended warr. through the Honday...

ok so in the last week my car overheated. i have changed the radiator thermostat water pump and all the hoses and it still is leaking coolant what else can it be????????

Hi, A couple of months ago my wife got home from work and complained about smelling coolant coming from her 2004 Ford Explorer XLS (with the base 4.0 SOHC). I went outside to check and found a very large puddle (pool?) of coolant on the ground. Looking around I found a pretty big leak coming...

Hi there. I have a 91 Explorer that my dad and I recently finished an engine rebuild on. We suspected a blown head gasket a couple of years ago and just got done putting it all back together. Has nice shaved heads, all new gaskets, and cleaned block (all acid dipped). After getting everything...

I've done a search and seen that a few of you have tackled this issue before. I just purchased the truck last week but I'm moving to PA in a few weeks and took it in for an oil change, tire rotation and to get a basic inspection. They came back with a couple of minor things and that there's...

Hello everyone, I have read through several posts- and you guys are great. I did do a search on the forums, and did not see anything on my issue: My problem is with my coolant/radiator. I have a 1996 Ford Explorer and the check engine light came on. When I did the free diagnostic test...

I tried to find the answer in previous threads but i didnt find one that really answered my questions. I have a 1995 explorer 4.0 OHV and it has 123000 on it. I decided its probably due to have the coolant changed. I see the drain plug on the radiator and i know that will get a lot of the...

on a 1996 XLT 4.0(x) OHV ...something is leaking onto the exhaust manifold causing it to smoke from under the hood on the rear driver side. i cannot tell if it is oil or antifreeze nor can i see where its leaking from. it seems like it coming right up from under the last spark plug...

Firstly, hello everybody! I've been lurking around these forums for a few years now, finding little tidbits of advice as I needed them. I've done my fair share of repairs based on the knowledge that I've found here, but it now seems that I have an issue that I can't find a clear answer to. So...

Hey everyone, I have a 2000 Explorer Sport with the OHV engine. For the past year or so, I've had a coolant leak but I could never identify where it was. I finally found the spot, and I took a picture: http://imageshack.us/photo/my-images/638/20110426132935.jpg/ The leak is coming from...

Please help! This problem is driving me NUTZ! The temperature gauge on my '93 XLT is possessed. The temperature gauge used to stick to N/O once up to temperature. Now, it can go up past L and back down to below N. After a period of time, the fluctuation will stabilize a bit but continue...
