3/4 NPT Plug Location

Does the heater instructions say to use a sealer on the adapter that goes into the block?

I always put red loctite on them but I'm not sure it makes any difference. I have never had one come out though.

I second the red Loctite......

What about Permatex sleeve retainer?

I guess you could if it says it's good with coolant, but I never have.

So I went ahead and used the first freeze plug location (from the front) on the left side. I used this location because it was the only one that was completely unobstructed. The 3rd and 4th locations were blocked by the starter. The starter is only 2 bolts but the lower bolt is blocked by the loader frame. I didn't really feel like taking everything apart.

The freeze plug ports are definitely horizontal slots on the MX so it's impossible to spin the plug to remove it. I ended up drilling several holes until I found a good place to thread a large screw and very carefully pry it out with a pry bar against the block. This was difficult because there are several hard lines around the area but it's not impossible.

I tapped the adapter in and I'm currently waiting for the loctite to cure before I try it out. Hopefully it heats just as well as the recommended mounting location.

I just installed on in the third plug. my concern is the

Don't think Frank will answer, he hasn't been back on since 2016, the heater best location is in the frost plug location behind the hydraulic pump, but you won't notice much difference putting in an accessible frost plug location on the right side, in front of the starter.

Is there a horizontal slot in all plugs? I installed one on left side, 3rd plug, by the starter. That location has the horizontal slot. about half the hole is blocked. The slot does not look big enough for the fluid transfer to be enough to warm the engine.

It will work fine and dandy, and no there is no clear open port anywhere in the block.

It will be fine, they are all that way.
