Tank Heater on 4230

Want to put a Tank Heater on my 4230. Was wondering where I would tap into to get the most efficient heat. Any thing will help. Thanks
 
I have to asked why you want to put a tank style heater on a JD 4230??? They have the hole in the block for the heating element. This is a much better way to heat the coolant.

The tank heater on my early 4020 heats up the block faster than the internal heating element on my 4240. I think the tank heater is twice the wattage as the internal heater. And yes the internal heater is 3 years old where the tank heater is close to 15 years old.
 
On our 3020 tractors, the cold coolant line comes out of a fitting on the left side of the block where the drain cock is. This line goes into the bottom port of the heater. The warm coolant line goes from the top of the heater to a fitting screwed into the cylinder head (remove a recessed hex head plug to put in a hose barb).

On our 1970 3020, the cold coolant line wraps around the front of the engine under the water pump, with the tank heater on the right side. The other 3020 is a 1967, and has the heater on the left side of the engine, but I do not recall how the warm coolant line gets to the right side of the engine and into the cylinder head. We have found tank heaters to warm up a tractor much faster than the "in-block" elements.

Good luck,

I agree. A burned out tank heater is a lot easier to change on a -15 degree day than an in-block one. They do seem to heat better too, probably because they can be bigger.
 
If you would check the actual temperature at the cylinder the internal block heater DOES heat that area much better than any tank heater. The element is heating the water directly in that area.

I hate tank heaters. They have many more problems and are more of a fire hazard. I know of two barns burnt down because of a defective tank style heater. I have never heard of a block heater causing any trouble.
 

Glad to know that you want to use a coolant heater instead of ether, a magnetic heater or a tiger torch that some people here think are acceptable options.
Hot line from tank heater connects to the highest port available under the thermostat. cold line to tank heater connects to the lowest coolant port on the engine.
Tank heater can not be above the top engine connection nor below the bottom engine connection. Can not run warm coolant downhill from the heater into the engine.
 
Thanks, I think I got it figured out. A tank heater does a way better job up here where it gets very cold in the Winter.
