    Works well. Put on a John Deere 3320. Warms quickly and allows easy starts in freezing weather. Much less expensive than buying from dealer.

    Installed without too much trouble in a Deere 2520 with the 3 cylinder Yanmar, so I’m sure anything else with that engine it would fit. Just a note, it needs a 1-3/8″ socket to get it on and I couldn’t find that info anywhere ahead of time. It took quite a bit of force on a long breaker bar to get it to seal up, if i were doing it again I’d put some pipe sealant on it ahead of time. I only plugged it in to test it out and it did heat up the area around the plug. Haven’t had to really use it yet, but I’m sure it will work fine. Also, note that it does not look like the picture, it is pipe threaded.

    Bought this in the fall and installed into my kubota B series tractor preparing for winter. Worked fine until I needed the tractor and it was -1 F. Burnt out or something. WTH?!!!

    I installed this heater in the block of my Kubota B1700 tractor. 1” npt thread fits in the threaded block port. Drained and refilled coolant at the same time. Ran motor for an afternoon. No leaks after install.Decided to try the heater the next day. As soon as I plugged it in there was a noise from the heater and the breaker tripped. Unit does not heat block. I verified this with my laser thermometer. Amazon is replacing the item. Will follow up when the replacement is in.

    Installed fall of 2018 instead of OEM on John Deere 950 utility tractor. Worked for the ’18-’19 winter season. When I tried to use it this winter it was nonfunctional. I would not recommend this part.
