Gehl SL4640E engine heater

Husker24 · Jan 6, 2024

Hello,
I have a Gehl SL4640E with a Deutz TD 2009 L 04 engine, I am trying to figure out the best way to install some type of engine block heater. The parts manual I have shows a threaded block heater installed near the coolant temp sensor but mine just has a freeze plug located there on the engine. It doesn't look difficult to access but I was hoping I could just remove a threaded plug and screw in the block heater. Does anyone know if there is another location that I could thread a block heater into? Or would a different style of engine heater be simpler to install?

I spoke with Samuel(Deutz) in

Montreal and he says it goes in the oil pan Deutz Part number 300235

Deutz 303617 should be the correct one for water cooled td 2.9 engine

Thank you for your replies. I think I would like to go with a circulating heater but do no know for sure where to connect my hoses. There is a little stub hose capped off coming from the thermostat housing, I am guessing this is where one of my connection would be but where would I connect the other hose?

That maybe for a cab heater connection, which would probably work, is there another connection, at the inlet for the lower radiator hose?
if it would be mine, i think i would get the one that goes into the block, a clean installation n dont have to route hoses etc and works as well if not better

I believe Firefighter to be correct with Deutz 303617.
Here is how it would be installed using Locktite:

Now to find a reasonable price for the heater.

Supposedly, the OD of the engine facing side part is 1 1/8"

Thank you for the suggestions. At a quick glance I don't see another connection by the lower radiator hose but it is kind of tough to see. I tried to measure my freeze plug and it looks closer to 1-1/4", at least on the outside, the hole must be tapered to 1-1/8". Watching the video, I don't think I'll have room to square up and drive anything in. I'll check with the local auto parts store and see if they have something 1-1/8" that wouldn't hit on anything internally.
