Block heater removal

[furiousgeorge]

How do they come out? I've got the nuts off, but it won't budge. I soaked it with WD, hammered on it, heated it up and did it all again, nothing. My manual has nothing about them. The studs have a slot, but neither move, and I don't want the wreck them any more then I already have. Any help?

my block heater was basically a headbolt, is that how your is?

[furiousgeorge]

Nope, mine is like a modern one, in a frost plug hole on the drivers side of the block.

FG, drill some holes through it, and yank it out,would that work, I have removed these types, twisted them out.

Been a fewhile years but just in case you still remember...how did you get the block heater out....and if so, did you replace it with another one or put in a frost plug?

[furiousgeorge]

I just punched a hole through it and pried it out. I got another off a friends parts truck.

[Mr Bee]

 Would I be correct to assume that once you got it out you could have replaced it with a regular core (Welsh) plug?  Or does the hole in the block look different once you get the block heater out?  I'd like to remove mine and replace it with a regular plug.  BTW. ...was it 110volts, 240 volts or 6 volt going to the heater?

Each heater  I have removed came out in pieces.  Fortunately we have no need for block heaters where I am, so I replaced  them with  new core plugs .... P14.... I think the number is. 1 5/8.

Don't use the more familiar cup type.

The best way to put these in is to put the plug in the  hole, put a hammer or broad drift over the plug then strike the hammer with another which tends to flatten the plug, making it expand around its circumference.

oddly, the block heater that came in my truck was a special head bolt....with a heating element...I should find it and post pics

[furiousgeorge]

I had one that was the head bolt type, and two that are regular frost plug ones. I assume it was a 110v? My 50 is a regular one that seems to work good off regular house power.

[Mr Bee]

Mine is a frost plug type for sure. No harm trying 110v on it since it's still in the block on my workbench.  It should either not work, or work, or start to smoke!
