Clean as can be but thanks for the reply

2007 Mountaineer V8 - My charging warning has been coming on occasionally lately. It will come on after driving a bit and stay on for a minute or two. Then it might come back on for a minute or two again. It did it this morning on the way to church but not on the way back. Two days ago, I...

The JB Water Weld did not work for me. Could never get the pipe dry. So I went to a radiator shop and he advised buying the part rather than trying to aluminum weld it. Got home from there and it was suddenly leaking a lot. Bought the part and it should be here Sunday. I am letting the...

So I just went out to scotchbrite the welded area and noticed that the backside of it is very hard to get to due to that other pipe running behind it. Did you use anything like a Popsicle stick to spread and massage the JB on the back side? Or did you remove the stability clamp that attaches...

I would agree

Thanks Nice GTCS Love that color. I clearly am not as agile as I once was. Does not help with our low slung Mustangs LOL.

The less expensive piece with the Y is sold with just the Y and hoses. It does not include the other stuff that comes with the part listed above. But no matter. I am not dissing the dealer. Heck, it took me and all the great folks on this forum over two weeks to track down this leak. I...

Scotchbright pad. Good idea and I have some. JB weld will be here later today. I am thinking you applied several layers to build up the strength of the pipe where the weld is. Sounds like you waited an hour between layers. I did find the part. It is most of the under hood heater plumbing...

A couple of other things to add. Early on in the saga I took it to a local Ford Dealer for a diagnostic fee of $100. They did pressurize the system. They found some dampness on the radiator by the lower hose. Not dripping. It had never dripped before from up front so I dismissed that. I...

Ding, Ding Ding! You are a genius. I just got home from my travels today. Had the heat on, then the AC on and back and forth. Then for the last 15 minutes had the system off. So, I just went out and found coolant on the underside of that pipe right by the weld. Thank you, thank you thank...

Not sure I understand. Are you saying that with the heater valve closed on the one hose, the core is still being pressurized by the other hose. If so, I had not thought of this. But, if I am reading this right, you are saying that the core is always pressurized with regular AC on but not when...

At this point, I am not sure of anything except the sun which did rise in the east again today. When I first spotted the "liquid" on the floor two weeks ago, it was definitely antifreeze. Tasted so sweet that I do not think any appreciable water was mixed in. Also, I do think you are right...

Will do.

Just looked at it online. Looks good. What type of leak did you have and I assume it worked well for you.

So, I went to the Ford dealer. $1,800. 7 hours of labor at $200 per hour. But the Motorcraft heater core has been on back-order for a while and there is not ETA. And, they will not offer any guarantee without using the Motorcraft part. I found one on Cardid.com but still not guarantee it as it...

I have read that taking out the front seats will make accessibility easier. What do you think? Keep in mind that I am 71 years old and not as flexible as I once was. I will take it to the Ford dealer tomorrow for a quote. They had the car for two hours two weeks ago and did not properly...

And the chapter for replacing the heater core is only what? 1,000 pages? LOL

Just bought it. Thanks. Looks like I will not get the download until Monday. This should convince me to either try and do it myself or have someone do it or sell it to CarMax

So I took it out this morning and ran the heater for 10-15 minutes. Now, an hour later it has lost 3-4 ounces. Dripping more from the center of car off the transmission cross member and exhaust cross over pipe. So, that confirms the theory. I wonder if a radiator shop rather than a Ford...

It is going to get down to 58 overnight so I am going to take it out early in the morning and get it up to temp and run the heater just to verify that valve is not leaking. Guess I will get a new car. The only ones I will consider is a Kia Teluride or Hyundai Palisade. Problem is they want...

I am an old retired guy so I don't go out in the snow much at all. Can always take my wife's Murano if I have to. Which hoses are the inlet and outlet?

Here is a thread that supports this theory. https://www.explorerforum.com/forums/threads/heater-core-leak-can-i-fix-it-myself.403188/
