coolant

I replaced my coolant sensors almost a year ago and I’m worried I have them backwards. I’m using the dy-1144 sensor to control the gauge on the drivers side one wire connector, and the SW5174 fan switch for the computer sensor on the passenger side two wire connector. Any experts here that can...

Back in 2015 my heater hose broke and caused my vehicle to overheat, and I’ve replaced every gasket down the lower intake since then, due to leaks. I started getting a misfire(p0304) a few months ago and was losing coolant. I added some k seal and it went away. I drained the radiator to get rid...

Howdy ya'll, My 1996 Explorer 4.0 XLT has a minor coolant leak coming from the passenger side of the engine compartment. I have looked on numerous parts sites and diagrams and I can't find the part number/name where it's leaking from. I've searched through other coolant leak threads here on...

I have a 2017 platinum currently at 20K miles. I recently checked the coolant PH level with a meter. It reads 7.2. Can'f find the normal coolant PH range of this OEM coolant (Motorcraft orange). Does anyone know if it's within the normal range? I know from high school chemistry class that 7.0 is...

Need a bit of help here. Just did a 750 mile round trip to visit the daughter at school. The morning after each leg of the trip, the radiator was about 1/2 gallon low on fluid. I've got no puddles under the vehicle, no liquid on top of the engine, can't smell it driving down the road, no...

I will be checking my coolant sender and gauge sensor soon and I'm trying to find the resistance values for them but am having no luck. Anyone know the values for these? It's for a 03 ST

When I parked today on an upward incline, shut off the engine and got out to look under my Ex, coolant was coming out in a stream which eventually dwindled down to a drip... I thought I've been leaking oil, but it appears it's coolant which is good and bad to me. Coolant appears to be coming...

Bought the car as a project recently It's a limited AWD 5.0 v8 just wondering how much one would charge to replace all the freeze plugs around the engine does this require pulling the engine? Should sealant be applied ? And pretty much I just want a rough estimate of what I'm looking at...

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...

Hey guys. So I'm low key freaking out right now and seriously frustrated. My engine was smoking pretty bad only when I turned it off and I was leaking coolant. It wasn't a steady leak. I could go three weeks without losing a drope then lose over half a gallon in a night. I don't know what the...

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...
