Block heater

[SnowDrift]

What is the recommended block heater for our trucks? OEM would be just fine for me. I see Unique Diesel carries them.

I did find a Katz 11612 also.

Theirs is short and stubby in comparison to the others I see for sale which look longer. I don't know what the factory one looked like and I can't check it since someone threw my old engine away...

Basic difference is the wattage. OEM was 600 you can get 1000

The heater in the block of my truck, I think, was OE and it kept the engine nice and warm even at over 20 below zero.
It would even warm the hood enough to melt snow and create ice when it got colder.
I’m now thinking of hooking into two 600 watt units.
One on each side if there is room around the engine mounts.
Of course though, a pair of 1,000 watters and the engine would be near operating temp during the coldest cold spell.

Do any have a built in thermostat?

I don't know for sure but I think all of them have a built in over heat shutdown

I plug the backhoe into an external thermostat, I lay the sensor on the block, to keep the block at least 60 degrees.

If I know I'm going to start it and have time, I skip the thermostat and plug directly into the power bar. To warm it up just a little bit more

I'm not sure I'd want to do that on the trucks or Jeep. They're not daily drivers and the cozy warm engine compartment might be inviting to mice

I was to the thinking that the watt rating is the upper limit control.
