4269250M91 block heater on GC2400 simple to do

4269250M91 block heater
took me about 35 minutes, longest part was getting air out of cooling system. I used a 5/16 drill to score (NOT drill through-important do not want shavings in block) and create a weak spot on the block plug. smacked it with flat chisel to bend and rotate it, used flat screwdriver to rotate it out. took 5 minutes. I had already cleaned the 2 bolt holes on block and ran bolt in and out of both.
wiped out the plug hole put little rtv behind the oring on block heater used a socket to tap into place and ran the bolt in. I used the rear bolt (GC2400 did NOT have a ground bolt there on front) for now as I will be getting another bolt to fill the unused hole.
filled coolant ran it until hot, let it cool and checked it. no leaks.
tomorrow morning will be below freezing here so I will plug it in for a few then look at gauge and feel hoses/rad when starting to see if working.
I orientated it with plug UP to clear the oil filter, was a little tricky getting plug attached and screwed in due to angles.

Good job, and yes they are easy to install but still pricey.

I have only needed to use the block heater for about 45-60 minutes even in -40F.

I don't expect to run it often but...its there when needed. got to install battery tender next and make it simple so wife can use if/when needed

Instead of leaving the cord there all the time, I remove mine in the summer and cover the heater connection with a garden hose cap. Saves wear & tear on the cord....

been debating that. got one unit we do that one another we don't. unit we do we ended up with contact problems. both those 2 in high dirt/dust conditions.

LOL mine came w/ it disconnected so if I had forgotten that would remind me. also have experience with a few others. but if tractor came with it connected I could see how easy it would be to not notice that.
