Removing Heaters / Looping Coolant Lines

[somewhereinusa]

I think, but not at all positive, if one nipple is lower than the other the water should go in the lower. My big front heater has an air bleed, it is on the outlet. If the nipples are the same height I don't think it matters.

I am going to have to keep the 80' of rubber pipe, but I think I'll move it under the bus and run it inside the frame rails. Covered in pipe insulation and clipped in place it should be fine ... I hope.

Hello Twigg.. I have a RE and was thinking about doing the very same on mine... How'd it work for you?

Thanks!

Same here. Already removed all but the dash but haven't put the lines under the bus.

So as mentioned a couple of replies above...

My plan is to just go ahead and replace the existing 1" outflowing heater hose that's in my bus (2000 RE International T T444e) , as it is 20 years old.

The best deals I've found on 50' runs of hose are on amazon, but my question is will this (1) be an acceptable replacement:

or does the bus require the (2) more expensive heavy-duty hose to run safely:

I am keeping my hoses since I have an RE. It helps with the cooling to some degree.

I suppose I should really be re routing them under the bus but my layout makes it possible to build around them.

Use gates green stripe or napa gold stripe. Gates's safety stripe is their cheap line and I wouldn't recommend it.

Use cheap stuff at your own peril. An engine can dump it's coolant contents quickly thanks to a ruptured hose. If it's under the bus and behind the driver, you'll never know it until the engine has overheated $$$$.

This is a dilemma we've had and I'm still tossing around how to handle it.

New silicone hoses inside the bus?

New quality non silicone hoses?
Inside where originally located?
Rerouted under the bus?
Installed inside some sort of water tight channel with a water alarm? (esp important if kept inside)?
Replace the existing coolant valves with ball type valves?



Building a bus is a never ending serious of questions and choices. I wonder if the questions and choices will end when it's done and on the road. Somehow I think they won't.

Inside the bus is protected from road hazards and debris. Inside the bus also makes a mess if any issues arise. Rock and a hard place.

Silicone hoses you say? Read here https://motoiq.com/silicone-radiator...or-the-street/

Silicone is oem in certain areas, such as egr coolers and near any exhaust component. But unless high heat is something I'm encountering, I'll stick with epdm. Quality epdm is cheaper then Chinese silicone, and will last longer and be more durable.

Newer buses have coolant level alarms. Whether or not they're functioning is always a gamble I guess.

If I put them outside the bus they'll be protected. That's just way too long a run in a pusher to not protect them.
