Burped out some coolant

[sixsix]

Wife came home after work and parked the truck in the garage. About an hour and a half later I went out to get something out of the garage and noticed a nice pool of reddish coolant in front of the truck. So I gave the whole top and bottom side of the engine a good once over and this is what I came up with.

The coolant overflow tank was pretty much bone dry. Took a good bit of water to get it back to the lower line on the tank. Filled it up to there. All the coolant was dripping out of the square access plug on the skid plate. The same one you would take off to catch the oil filter drain (the rear drain). Put the truck up in ramps and took the felt skid plate off and began poking around. The turbos were bone dry. The ecu looking thing that is right above the skid plate where that plug was that I removed was wet. And could kinda tell that it had dripped off the front of the engine. The oil filter cooler lines were dry, and so was every coolant hose I could see. Didn’t see anything around the thermostat housing...I couldn’t get a good visual on the water pump tho, but I’m not sure if that is the kind that would leak externally or just dump all the coolant into the oil. Speaking of the oil, it was clean as well. So I couldn’t find any signs of drippage any where. Took the truck out for a 10 min rip around and parked it and didn’t see anything anywhere....the overflow tank was empty again tho. I’m gonna check the tank in the morning and fill it back up if need be and see if anything leaked overnight.

Anything else I could possibly check? I couldn’t find where the overflow tank releases to, I saw it go in the fender by the air box but I lost it after that. Is it possible that it could have just over pressured and burped out?

Is the rest of your cooling system full or empty? (Note: check when cold)

If full, your overflow tank or the hose going to it is cracked

If less than full, leak elsewhere

What he said...you have a leak. It should not lose any coolant.

I told my wife to keep an eye on the ground for anything while she's running around today and I'm at work. Won't get another day to see it cold and look at it till the end of next week. I checked over every hose and didn't see a leak from any of them. I'll check again when I get home.

What does your oil look like? Also, look on the inside of your oil fill cap. It should not have anything that looks like peanut butter on it.

Oil looks and smells fine.

The wife said she never noticed any leakage today while she was out. I'm gonna check the overflow tank level when I get home from work. F150 peeps had issues with the tank itself leaking so I'm going to inspect that a little better.

I had something similar happen on my 2014, turned out it was the water pump leaking out of the weep hole.

Good luck, I wish you a simple and inexpensive fix!

Well it didn't leak at all yesterday and the overflow tank was still full when I got home. I dunno. I guess I'll keep an eye on it.

Having similar problem with occasional coolant leak on 2015 EXP.. Dealership has changed several hoses. Not sure that fix problem until drive for a while.They are working of a strange sound now that may be a air leak around the turbo. Driving loaner now. It has been in the shop a better part of a month now.

Found the leak and got it on video. Looks like the water pump? You can see it dripping right behind the crank pulley and I believe that’s the water pump above it.

So apparently what I saw wasn’t the leak. I brought it in to the dealer and they said it was the heater hose on the back of the engine.

What the hell is a "parish sales tax"? The local priest is collecting forced donations at the dealership?


Also, I wasn't aware there was any coolant hoses at the "back of the engine". Was it a heater core hose? If so, then that's pretty steep for something that's exposed and easily accessible (at least on the V8 it is, not sure about the EcoBuddy engines).

Sort of like a county sales tax. Some states call countys parishes.

Oh, ok... got ya.


I asked because there was a scam up here in a large metropolis of Kanukistan, where many restaurants colluded to collect a "tax" that was in fact a "voluntary donation" for some Leftie cause of theirs : they would add an extra "tax" to your bill and would only remove it if you noticed and asked them to. People who missed it and paid the bill were duped!

$600?! I hope they at least gave you a reach-around while ******* you in the ass.

I'm in Louisiana, we like to call our county's parishes for some reason.

I also had them do some other stuff while it was in there. But just the hose replacement would have been $440. They are a little expensive on the parts and I never would have imagined the labor would have been that high. I haven't checked under the hood yet to see where this hose was at.

Is that 3 hours labor to replace a quick-connect heater hose? They can put up a fight, but for a change mine didn't. I think I did two in 20 minutes.

fl1z18472b = $55.79
bl3z18472d = $16.76

They're essentially selling them for 200% of what you can buy them for yourself. That labor is the real killer though. That's like a 1-hour job (I replaced these same hoses a couple years ago.).

And folks wonder why many call them "stealerships", lol...

Yeah this may be the last time they see a dime from me. I've bought a couple of Ford's from this dealership in the past and never really had a problem with them. But when I bought the Expedition I could have sworn I told them I didn't want the extended warrantee but when I was going over the paper work when I got home I noticed it on there. Yeah I know, my fault for not checking while I was there. I was gonna go back and get a refund for it, but my wife wanted to leave it so I did. I did come in handy when the power running board went out, and I thought it was gonna come in handy for this job too, but the service writer called and said that the extended warrantee was only good for 75k miles. Really? That doesn't seem very extended to me. It is what it is...I blame no one but myself. It won't happen again that's for sure. Looking at replacing my Honda Accord that I drive for a Ecoboost Flex w/appearance package, and it certainly won't be from them.
