Recirculating Coolant Heater?

[2INSANE]

Has anyone ever tried a recirculating coolant block heater? One that heats the coolant and moves the coolant at the same time?

We use them on our larger diesel fueled generators at tower sites. They do work well on keeping the engine coolant in a warm to hot temperature range.
Easier starts and the engine is ready to take the full electrical load when the transfer switch connects the building load to the generator.

Only ever had one burn out after nearly 20 years of continuous use.

I have not used on on a CUCV.

Can’t help you as I’ve never used one of those but there might be some good info at ExpeditionPortal.com.

Those folks build some wild overland expedition vehicles and often used multiple types of coolant heaters and exchangers in various different ways.

Let’s talk about this. So the outlet would be a t fitting on one of the heater core hoses and the inlet would be somewhere on the lower end of the block…. So where is the best place on the lower end of the block to tap into?

Perhaps a freeze plug on driver side with a bung welded to it?

looks good to me. Let us know how you rigged it.

I see a lot of these on the standby units I work on, especially the Generac and Winco units. Handful of them I've replaced due to leaks. One burned out because a freeze plug leaked draining the coolant, then the heater went full on meltdown...

Other then that pretty good. Probably can't find one better for the money.

If no one has done one of these recirculating coolant heaters on their CUCV, I’ll do one and do a write up on it! I think this would be a much better solution to warming the motor and radiator at the same time with only one unit.

It definitely would be a useful tool in a seriously cold environment.

Would think it would be a BIG PLUS to add valves on the block (inlet and outlet) to shut it down if a hose broke or the plastic heater cracked. Moving water seems like a heck of a plan to me too!

Look at a Kat's Heaters Thermostatically controlled tank heater # KH13150. 120 volt- 1500 watt.
These have been used for a long time on tractors and trucks.

I thought there was an older thread on this and that it couldn't be done because of the way our coolant is routed. I have used these types of heaters on my older diesel VW's with really good results and would love to put one on my 1009. I hope someone finds a way.

I have a cold advance switch, radiator needs swapped and thermostat needs done here soon. Will have to drain the coolant. Will be a perfect time to experiment and report back how it works.
