Block Heaters

gbirky · Sep 4, 2002

With cold weather on its way, and the difficulty I had starting my tractor last winter, I want to install a block heater in my YM1301D (engine is a 3T70B). Does anybody out there know a specific block heater that will fit this tractor? I would guess that the closest US model is the YM169D, though I don't know what engine is in the YM169D.

Hello Greg,
My YM169D has a 3T72HA-A engine. Afraid I can't help you with which block heater would work. It doesn't get cold enough around here (N.W. Washington) to need one. I'm sure one of the dealers in the mid west can fix you up. Jim

Hi Greg:

Up here in North Idaho on the Canadian border we have put block heaters on many compacts for customers and ourselves. They work just great here and should back there also.

The best place to buy one is at your friendly parts store. You need to find a spot on your engine which has the most open space and measure it. Then head to Napa, Carquest, Parts Plus or the like and decide which style fits best.

The best type is the magnetic against the block if you can find one to fit the 1301D. There is also a new tube type which is flexible and mounts in odd shaped places. There are some small soft plug mounts if no magnetic or tube. Hose type placed in the hose should be the last straw if only to save time but it isn't that much work.

There are lots of choices so check a few places. Prices here are $32 in hose, $39 magnetic and soft plug, and $49 for the new tube type.

Hope this gets you started.

Thanks for the replies. I was hoping to find a block heater that will go into a freeze plug hole in the block. My 3T70B engine has freeze plugs on the intake side of the block, and threaded holes with plugs on the exhaust side. I wanted to get a heater that has a coil with the right size and shape to insert into the block. I think that is the best solution - getting heat into the coolant that is in the block. Second would be the hose type.

I have contacted a nearby Yanmar dealer and asked what would be appropriate. I haven't heard back yet.

I have the Yanamr block heater that works on most Yanmars with the screw out block plug, sheaftractor@coiinc,com

I have used 1 1/4 " lower hose block heater on quite a few, I don't remember all the models, but the ones I remember are YM 2000, YM2500, YM2610. They work very well.
