Title: Heater installation
Post by: DaveB on June 29, 2011, 04:46:50 PM
Anyone got any tips/hints for removing the plug in the head next to the firewall to install a heater?

You could use a hole saw that is the same diameter or a touch smaller.

To remove a pipe plug from the head?

Dave, does the plug have a square head that a wrench would fit over? You could get a 1/2" drive socket that fits over the square head and use a strong-bar to break it loose. I would precede that with an extended soaking with PB Blaster.

Yes, it's a square plug...unfortunately (Ifound out the hard way) it is slightly smaller than a 1/2" drive, and very soft steel! I was reluctant to use heat because I thought I had read somewhere that it was risky around a cast head. Of course to make things more interesting, it is only about an inch behind the #4 plug, and under the cowl. Guess I'll try the PB Blaster. The other method I tried was to run the engine until the head was hot and added liberal doses of liquid wrench....Obviously to no avail!

Oops.  I'm an idiot.  I should have read the questions a bit closer.  I have "plugs in the firewall"  on my mind as I am trying to remember how the hoses for my heater were run.

 Larry is absolutely right on.  My head plugs had already been removed.  Good luck on your removal Dave.
