How to Install circulating heater in a 4240

tool · Jan 8, 2010

Hi all,

I have a 4240 JD with a 158 loader that I use for feeding cattle here. It"s been bitter cold and I"m not able to put it inside so it"s been hard to start.

I have a circulating heater here and I"d like to find out the best way to install it.

Thanks for the tips!

Your tractor should have a plug under the oil cooler on the left hand side of the tractor. This is where a block heater goes. If yours doesn't already have one this would be a very good time to put one in. Mike

Generic instructions are to #1 find the lowest point of the cooling system on the engine block.#2 find the highest point of the cooling system on the head or manifold but below the thermostat.
Good to hear about somebody wanting to use a block heater. Instead of asking how much ether to use.

I agree with mike, the late 404 engines and all 466's (i believe) had the freeze plug hole under the manifolds on the left side (as sitting on the tractor). Drain coolant, pop freeze plug out, install block heater, refill engine/radiator with coolant and while your at it, add john deere coolant conditioner or wix cool, amount per instructions.

I have the block heater, but by my experience a block heater is not as effective as a tank style heater.

Hence my wish to install a tank style circulating heater.

Block heater works great in warmer temps but won't cut it at -35F.

The block (frost plug) heaters are usually low wattage (600 watts) and meant to be plugged in overnight for a good warming. But, Zero-Start does make one special for the 4230 that is 1000 watts (# 8602050). The tank heaters if sized right, are better for a quicker warm up when needed. Many tractors have both.

As far as the tank heaters that Deere sells . . . Deere does not make them. They are just industrial versions, like the ZeroStart Phillips Series 41 Industrial tank heater.. What make it different from the cheaper ones is not the way it works. Just the fact that it hsa a take-apart reservoir so you can replace the heating element if it burns out. You can buy them direct and avoid going through Deere - but can't say if it's always cheaper that way. Sometimes such things are cheaper from Deere, and sometimes twice as much.
