I’m looking for a coolant tank to replace mine which is leaking. Any help would be greatly appreciated. Stuck in Ely NV.

Good morning Ken; Sorry to hear that the coolant tank is leaking. I can't remember what a Beaver coach has for the coolant tank. It a plastic tank or a metal one? Source Engineering has tanks as well as Verhnks, I know I spelled that wrong, and not sure they are making them right now, but Tallan has stainless tanks also. Try using Bing or Google and see what comes up for replacement coolant tanks for your year of Beaver coach. Depending on where the leak is you can still drive your coach by just turning the pressure cap counter clockwise to the first stop. The tank will not be pressurized and that will help stop pushing the coolant out with pressurized force. You will lower the boiling point of the coolant, but this time of year, depending where you are and where you are going, you just need to watch coolant temps and the low coolant alarm. This is all null and void if coolant is just pouring out of your tank. If you can't get a tank right away you could try some external sealers that are out there on the market until you get a new tank. Hope some of this info helps and good luck!

Verurink (sp) has it and going to order it overnight. Will try and put it in myself. Tank in now is an aluminum one that I replaced. I replaced the plastic one. Fingers crossed.

fwiw,

last I heard, tallin was going to sell what they had in stock then discontinue them. I think it was more work than it was worth, from what they tell me.

Source Engineering are no longer listing their aluminum replacement tanks, either

!

I ordered a new low coolant sensor with the tank and wire plug. It’s 2 wires same as the one on the tank now. Does it make a difference how the two wires are spliced? In other words is there a ground wire and a hot wire that need to be spliced a certain way. Or do the wires simply complete/break a circuit when coolant is above a certain level?

8.3Oilbuner · 10-20-2021, 09:33 PM

Good evening Ken; If the 2 wire system that you have on your Beaver is the same as on my 01 Windsor, it should not be too hard to do a wire trace. One of the wires goes to ground and the other to the low coolant light on the dash. On my previous 2000 Windsor that had the one wire hooked to the aluminum probe and was replaced with a 2 wire low coolant sensor, or the one wire on my 2001 Windsor tank that had one wire before the tank was replaced with a nylon tank and a 2 wire low sensor installed, I understand that it did not matter which wire was hooked where. On the 2 wire low coolant sensor, one wire to ground and the other to the low coolant light. If I am wrong on this I need someone to set me straight. I got this info a long time ago when you could talk to the tech's at the Monaco repair facility in Coburg Oregon and on both coaches everything worked as it should. Hope this info helps you Ken and as I mentioned, the ground wire should be an easy trace.

If the low coolant sensor misreads low coolant does it cause engine to derate if engine temps are normal? Or does it just cause light on dash to come on?

8.3Oilbuner · 10-21-2021, 03:46 PM

Hi Ken; THATS a great question and I don't have an answer as i never have had my low coolant light come on in 19 years of owning a Monaco Windsor coach. The low coolant light system is more involved than just an light on or off from what I understand. Not sure if it is tied into the engine ECM. Hope someone here has got the answer as it would be great information. Have read in other cases that a low coolant light can de- rate the engine, but not sure on what make or models.

kketterling · 10-21-2021, 06:38 PM

Got the new tank today and installed it. Used old sensor and it works fine. I’ll save the new sensor as backup and do some research as to how to wire it. The tank from Veurinks was top quality and bolted right up.

Thanks everyone.

jacwjames · 10-21-2021, 06:41 PM

On my 8.3 ISC Cummins has a coolant level sensor that reports to the ECM. My guess is that this could shut down engine.

The sensor in the tank is for the dash low coolant light, which I don't think will shut down the engine. On my rig the coolant sensor is one wire, that basically senses ground through the coolant and if coolant is low it looses ground and works with the Kysor Low Coolant Alarm to turn the light on the dash.

My guess is your rig may do the same thing.

kketterling · 10-24-2021, 01:05 PM

I was mistaken, my coolant sensor in the old tank has 4 wires going to it. Will have to get my wiring diagrams out to see what's what.

Did finally make it home with no further mishap.

Hey Ken, could you please explain how the old aluminum tank was leaking?

It had a hair line crack on one of the weld seams. Plan to have it welded now that I’m home but couldn’t find anyone who could weld it in Ely Nv.

I think the shop repairing blown hose created to much vacuum to suck antifreeze back into system and cracked the seem weld but can’t prove it and not worth pursuing.
