The alarm would have been from the low antifreeze sensor.

That's half the battle! Now to find a replacement, should not be too hard if you are in a Walmart area. Oreilly, Advanced, Autozone, Napa (I bet they have it for sure)

Hard to tell from the picture but it looks like someone put a straight hose on where a molded one goes and it tore.

Where is that hose at?

I would give Foretravel parts department a quick call or, better, an e-mail with pictures to see if they have a PN for that hose.

The mobile truck mechanic just left with the hose. They're trying to locate one.

I'm still confused about what antifreeze I should be using. OAT or not. I haven't had a chance to go through the appropriate manuals.

I thought Rotella ELC NF is OAT.

Mechanic is recommending Command.

What do you guys think?

Can't tell which hose it is, but here's the engine cooling section from the parts manual for a 2003 U320 - should be close to yours

First picture taken from the engine oil dipstick looking from the back of the coach. If you follow the dipstick down you'll see the bright blue/white area in the background. Those are the chassis batteries. The coupler is to the right of the dipstick.

If you noticed, I attempted to stop the leak with duct tape. That didn't work

The second picture taken from the area by the chassis batteries.

The third picture from the passenger side ftom underneath the radiator

In the fourth picture, taken from the area by the chassis batteries shows one of the clamps thay came off from the removed Fernco rubber coupler.

For coolant, two points:

Make sure what you choose meets the Mil specs Cummins designated for your engine.

Not what you have a mixture of coolants, you will need to completely flush before filling.

Never heard of Command.

I would stick with one of the majors that meet your engine's mil-specs AND is universally available.

This is the stuff I have in mine. It's already mixed 50/50 and does not require additive or to be checked with the test strips.

I am NOT a fan of the pre-dilute coolant. With the many gallons of "capacity" in the hoses, water heater, dash heater core, etc, unless you use compressed air and completely evacuate the whole "capacity", you are better off with the concentrate. Do the last flush with distilled water and then add 1/2 of coolant capacity with concentrate. Then, top off with distilled water. You don't care if it takes 1 or 6 gallons of distilled water. You KNOW when you are through that you will have the proper 50/50 mixture.

Mechanics are having a hard time locating the hose. Hopefully tommorrow.

For now, since the coach was on Rotella I will have the mechanic buy and use that. I have a Tractor Supply store a few miles away. Unfortunately, I'm having trouble unhitching the jeep because it is at an angle from the coach. I'll try to unhitch the coach end tomorrow morning after the monsoons end. First overnight stay at Walmart.

When I get back to Jaysay, I will find a truck service center to do a proper flush and refill.

Is there a filter used with the cooling system? I though I saw someone mention to change the filter?

There is a water filter. Get a blank one no chemicals.

Yep. That's what the truck mechanic told me. It's right in front of the black tank towards the bottom. He says when the antifreeze gets that low, the engine is going to shut things down fast.

All fixed. At $650 a bargain. Great mobile service in a walmart parking lot, to 9 pm and in torrential rain.

Yep, an easy job to do ourselves while parked at home but not while traveling on a schedule.

Everyday an adventure. I love it.

I had a flex connection between the engine block and a big coolant line spring a leak when we were arriving at a COE campground in Georgetown, TX. CoachNet dispatched a tech from Austin who drained enough out to replace the Gates Flex connection (from NAPA) and added 11 gallons of new coolant. $75 plus the cost of the coolant. Another CoachNet bargain. Next time at FOT I had cooling system flushed, the other two flex connections replaced, coolant filter replaced and the system refilled with the appropriate coolant.

Attached is a series of articles on OAT coolant I've collected over the years. Purchased our rig in March 2016 and beginning in Oct 2016 the radiator started dripping off and on, usually when it was cold in the morning, but not consistently. Spoke to FOT maintenance about adding coolant to the overflow tank to replace the lost coolant. They said Final Charge Global 50/50 would work. It's available at Walmart. Had the coolant tested many times since then during routine maintenance and there have been no issues. However, that being said, I presume the mechanics test the freeze protection, but don't know if their tests include a pH test as well. Hope so. I had FOT in the spring of 2019 tighten all the core to radiator tank bolts and add some Barrs Stop Leak. Haven't had any leaks since except the water pump weep hole. I probably need to have the coolant system flushed, but I hesitate to have the system pressure tested because of the previous leaks. Cummins in Las Vegas quoted me $14 coach bucks to replace the radiator in 2019. Don't want to go down that two rut dirt road.
