04 Journey Radiator leak ???

[Beabop]

We have antifreeze running down the drivers side rear rad. Is there a hose or clamp top left that we can't see (sure hope so) or shall we assume we have a leak. I keep reading about the dreaded heater core, I hope it is located in front of the MH. We are taking it in on Tuesday.

Could be a hose connection. I had one that just sort of started leaking at about 12,000 miles. I tightened it up, then tightened about 4 or 5 more I could reach. No leaks since.
Could also be a radiator problem. Usually a quick crawl under the rig w/a flashlight and you can find the problem area pretty quick.

You may have to open the access hatch in the back/under the bed to get to the upper hoses and clamps.

Your heater core is in the front of the coach, passenger side. Hopefully, you have a hose or fitting leaking and not the radiator.

On the driver's side of the rear radiator on my 2006 there is a small 90 degree elbow that screws into the left side of the radiator near the top 1/3 or so. On mine this elbow was not tight, and it leaked a bit. I would check there first and tighten it. On mine it needed about another half a turn. It can be hard to tell it is leaking when engine is running because of the heat and air movement in that area, but you can clearly see it once the engine is stopped. The 90 degree fitting was right behind the flexible material that goes along the left side of the radiator (when looking from the rear of the radiator).

Thx Clayton, we were under the bed looking today and seems to be in that area. It's getting cold here so DH is going to let the mechanics figure out how to reach it tomorrow.

Update, it was the hose and elbow from the overflow tank. Cost 1 1/2 hour labor some tape and clamps, antifreeze. $99
