BX25D block heater removal and replace

[Mowbizz]

There was some kind of “hack” for removing a failed block heater on a BX.
Anyone recall the what that removal hack was? If I recall, it had something to do with “garden hose” threads to wiggle the old heater out of the block. I know I have to drain the coolant and I have the “kit” for doing that…getting the bad “pressed fit” unit out is my question. How?

If it's the kind that has the nut in the end:
Turn it out, yes I know there are no threads but it will still come out.

If its the kind that has no nut:
#1: If you can get a pipe wrench on it and turn it.
#2: A big pair of channel locks or a small hammer and work it side to side to get it to pop out.

Thank you! That sounds pretty easy! Not quite ready to do the job but when I do your answers will be helpful!

This is the type of heater on my BX2370.
To remove it I use a female coupling screwed to a threaded pipe from a pipe clamp, use a couple of round weights on the pipe with a coupling and washers to keep the weights on the bar.
Thread the coupling attached to the bar onto the heater and use the weights as a slide hammer.
The heater comes straight out.
Use a large socket to seat the new heater and add some blue locktite.
It helps to have a second set of hands to support the bar while you slide the weights on the bar.

That’s the same heater I have..

That’s the same heater I have..

I went through a couple of these heaters before adding a timer and now it seems to last.
I remotely turn the heater on from inside the house, it's on for twenty minutes and off for five and so on.
I think the space is so small around the heater they get hot and burn out when left on too long.

Yes, this is the 3rd one for this bx.
I have a remote as well but not on a timer. Perhaps it’s time for one.

Yea heating it all the time is costly part and electric bill wise!

Not on 24/7 but maybe an hour at a time before I go out to blow snow…

These little engines don't take long to heat up:
This is just my opinion on years of use:
15 min normal cold temps
30 min really cold temps

You are correct!
