Original owner touted that there were "3 engine heaters" [in his written sale profile for the vehicle].

...I suppose I could call the past owner to ask this question, but I thought I would post it to the experts.

Does anyone know if there are 3 engine heaters [or any engine heaters] and how might they be activated???

"...if there are 3 engine heaters [or any engine heaters] and how might they be activated???"
Possibly: 1) Engine coolant heater, with an electric element in a coolant passage in the block. 2) Engine oil heater - same type element immersed in the oil in the oil pan. It is pretty much standard practice for diesels to have at least one block heater for cold weather starts. Each will have an electric cord with male plug coming off the heaters. Mine run inside, under the bed where a duplex 120v outlet is installed for this purpose; when they're plugged in they are on.
OR: Dash heaters and hot water tank heater which have (hot) engine coolant routed through them. My 86 Regal had the hot water tank "engine heat option" and it kept the water hot while traveling with the propane turned off.
OR: A combination of any three of these. Good luck!

Great information!

I think I've actually identified a couple of these items, but had no idea what I was looking at.

Should be easy to identify all 3.

I have three (actually four)engine heaters in my coach. This is probably the same for you. These are not block heaters, rather heaters that heat the interior of the coach or the hot water tank. The fourth one is in the dash (standard in all vehicles), another one is to heat the hot water tank while traveling and an other is located near the front propane furnace and blows hot air into the water compartment and the last is located under the closet in the rear of the coach next to the propane heater. They all use engine coolant to heat either a heater core for hot air, or a coil in the hot water heater. There is no control on the hot water heater, I have a switch located above the driver side window to turn on/off the heater fan to the water compartment and a switch on the lower right console with off/high/low positions to operate the heater fan in the rear of the coach. These are for cold weather travel. I use mine a lot on the fall and spring. The hot water heater is welcome all year round as we always have hot water immediately when we arrive at our end of the day stop.
