Installing Block Heater - MF35/Perkins diesel

Now, it's cold out there and I have more time, so am thinking of installing it.

I know that it just goes in one of the freeze plug holes, but, being a worrier, I want to be sure I do it right. After all, the local dealer initially sold me the wrong one - just because that's what his book showed! :)

Which freeze plug hole is best - please be very specific as to where it is...in fact, post a pic if possible.

How do I pull the plug...just drive a punch into it and pry it out?

Where does the heating element end up - in air, coolant, oil? I always assumed coolant, but now that I think of it, don't know for sure. If coolant or oil, does it have to be drained first?

I think that covers it all...anything I'm not thinking of?

Thanks all!

It's the "easiest to get to" that I've read over and over, but as I look at my engine - guess I'm too much of a newbie with tractor engines - the things I see that look like freeze plugs to me are in places that I'm having trouble imagining are actually ports to coolant channels. Like I say, just my inexperience and worry about putting it in a wrong port. That's why I asked for a picture if anybody could post one pointing out exactly where to look.

I thought of drilling a hole, but was concerned about chips getting into the coolant and possibly causing problems with the pump, so had decided to use a punch to start a hole, then use a heavy screw and cat's paw to pry it out.

Thanks again for your reply. Time to do it.
