I recently installed a cabin on my old 1968 2510 gas tractor that I mostly use for snow removal with a front loader and rear blade. Windows tend to fog up fast as we get as low as -40 here during the coldest of winter. I'm thinking of installing an aftermarket heater and was wondering were do you plug the heater hoses on this engine? Do you splice the radiator hoses or is there an easier way. Pictures or diagrams would be appreciated if available. Thanks for any input and Happy Holidays to everyone!

You should connect the heater hoses to the block. Deere sold a block heater for this tractor. It likely connected to the block freeze plug locations. Another location is the oil cooler but I don't think this engine used an oil cooler. Best to check with your dealer for suggested connection points. Do not cut the radiator hoses. Post pictures of the left and right side of the engine and perhaps we can make a suggestion.

Photo below shows how JD engineers thought heater core should be plumbed to engine BUT I'm scratching my head attempting to determine where the fittings attach to engine. Threaded nipple(key 14) is listed at 3/4" X 1-3/8". I have no idea where a 3/4'' orifice is located on 2510 engine. I was thinking one hose attached to LH side of engine block where drain cock is located & other hose fitting to cyl head,

JD 2510 engine block has no freeze plugs. Block heater for this application was canister type

Rear of the block has 1" pipe plug. Water pump might have 1/2" pipe plug. I think coolant heater used 1/4" fittings? I can no longer check on JDparts 🤬 (Anyone from JD reading this?)

The JD kit is PN AR38848 as shown by Zebrafive but NLA. The parts book shows pipe fittings but not where they connect. Of course the "new" JD Parts system does not show fitting sizes. The heater pictured by TxJim shows one hose is located "high" and the other "low". The cylinder head and block drain would be good locations.

Interesting that the 2510 block does not have freeze plugs.

Current JD parts photo for 2510 gasoline engine water pump doesn't show the 1/2'' plug you referred to. IIRC a hose from thermostat housing attaches to nipple(key 7)

Tex Jim posted the fitting size needed.

Although the image below depicts a engine block heater, it shows where to connect your heater hoses to the left side of the engine block.

Below is of a Gasoline Engine. Although as I recall, some of the Gas engine did not have the passages drilled and taped for access to engine coolant.

Talbot2510,

No pics? It did not happen till we see some pics, just saying is easy. I grew up with a 2510 diesel and would really like to see your cabin addition so lets see some pics.

Thanks for the replies, I'll get some pictures to help. As for the block heater locations, it seems to depict a diesel engine as I can't seem to locate these on mine. Also there is a small rubber hose from the top of the water pump to the front of the head, these look a bit small to use for my connections but might work with an adaptors but wonder if enough water will flow through these small openings.

How about a close-up of the LH and RH side of the engine? Perhaps we can tell where to connect.

Nice looking cab. I've never seen a cab similar to your cab & I've installed several brands. Have you considered a heater that operates strictly from 12 volts?

No I don't think a 12 volts system will suffice as it gets cold as cold can get!. Cab was built by a local vendor who used to supply many makes with this universal model. Very well made from heavy steal plates. It is known as a Michon cab with sliding doors. Interior space is limited and the sliding right side door makes my loader hydraulic control placed on the wheel housing farther back than I'd like, this to permit me to acces the battery box that is still on that side underneath. I can only crack it open about 6 inches just enough for a boost if needed.

Is there room for insulation? That would quiet the cab and also keep it warmer/cooler. Then a 12V heater might be enough warmth.

Yes I will be insulating it after winter and that will surely help just didn't have time this year. The floor is partially closed with a rubber mat but far from air tight as the right side hydraulic hoses and battery box are kind of in the way and must be accessible. If I can't get a prestone heater than electic will have to do. I have also considered a portable propane heater like those for camping but would rather have something more permenant. If I heat up the cab with a plug in house heater before use this might also help. It is still much better now than an open cab with snow blowing in my face. I'll get some more pictures today and you guys can see for yourselves.
