Blockheater help needed

[Mile High VX]

I have a oil pan heater on mine here in CO. It stick to the bottom of the oil pan and keeps it nice and warm. Plug it in at night and it's warm in the morning, even if it sits outside.

Ran the plug to one of the "holes" in the front cladding next to the front license plate area.

I have a factory Isuzu block heater, but since I just moved, I can't find it or the instructions that came with it...

But what I can tell you, is that it's threaded, & sealed with an O-ring.

A call to Merlin may help shed some light on this for you.

I know that you're looking for the heater warmth to come on sooner in the morning, but FWIW, mine has always started without much hesitation in temps as low as -35.

IMO, synthetic oil & an Optima red top help with that...
