Hello all,
I am trying to install a block heater in my 1985 FJ-60 with a 2F and was wondering if all the freeze plugs have the same amount of space behind them in the water jacket? The reason I ask is because I would like to install it in the 3rd freeze plug back from the front. It's tight up in there!:) Thanks for all your help guys.

The instructions that came with the heaters I've installed suggested the 2nd hole from the front......

Never tried any different..............

Yes, it is a bitch especially if the smog crap is still in tact........

I'm sure there's adequate clearence in the 3rd hole, I suspect they recommend #2 because its somewhat centered, closer to the radiator and will distribute the heat more evenly......
