| There’s a spot on the right side of the block towards the rear with a plate and two bolts. Agco sells a factory one for that location. |

Yes, that Kats number fits my AC185 and 200. Nice thing is it's 1000W another brand is only around 600W. I can't think of brand or number. ------------- AC 200, CAH, AC185D bareback, AC 180D bareback, D17 III, WF. D17 Blackbar grill, NF. D15 SFW. Case 1175 CAH, Bobcat 543B, |

PaulSamwel Here is my 185 which has the block heater installed on the RH side of the engine left of the fuel filter. The tractor was delivered new to our farm in 1975 with the block heater installed, probably by the dealer. Not a great close up pic of the area, but you can see the electric cord hanging down just in front of the starter  Hope this helps with your project ------------- 1963 D17D Series III. 1965 D15 Series II. 1965 D17 Series IV. 1975 185. 1978 716H. 1979 716H. 1965 780 Harvester/1R&DC. 1957 Model 73 SC 4 Furrow Plow |

| Nice tractor!Looks like the one you have is above and to the right of the starter.The one I'm thinking of goes a little farther back in place of the plate towards rear of engine and above starter. |

| Super nice 185 and incredibly close to looking like it just came off of the Milwaukee truck. |

Lynn Marshall Thanks. I will never forget the day it arrived at our farm, on the Dealers truck. Over time, rear tires replaced, new seat exactly the same, front tires upgraded from 7.50 and rims reversed, paint job and decals, every thing else factory (a few filters/muffler along the way). Paul Samwel I can see the access port you are planning to use. The block heater will cause convective flow in the coolant passages to warm up the engine metal everywhere the passages go. The engine metal will conduct the heat really well in all directions. One port location might be slightly better for overall heat transfer result, but the top of the engine, and the combustion chambers should warm up plenty to achieve a good starting condition. Other readers might have more info to share on best location for the heater element My experience with block heaters, like the one on my 185, and the external tank type on my D17 III Diesel, is they work very well, heat the engine up to very very hot (close to operating temp) so starting is like a hot day in July!!! Good luck with your install ------------- 1963 D17D Series III. 1965 D15 Series II. 1965 D17 Series IV. 1975 185. 1978 716H. 1979 716H. 1965 780 Harvester/1R&DC. 1957 Model 73 SC 4 Furrow Plow |
