so a couple of months ago i ordered a block heater from napa

(p# 605-3032)
and with the winter months rolling in i am now going to install it this is made specifically for a freeze plug hole diameter in the 5sfe and comes with excellent instructions it is not a "universal" product as toyota owners usualy come by
would anyone like a step by step with pictures on this?
i am currently running DEX COOL in my engine because it specificly says non phosphate antifreez is required with the bronze in the block heater (green fhospate im guessing) i drove all over N.H. trying to find a RED antifreez (last place i got it was a marine diesel repair shop and it was for a yanmar diesel)
so you might run into that problem
