Too %$&# cold here. Want to install a block heater in my D4 like this D2 (credit pic to the board, borrowed from bcwayne, thanks). Ordered from amazon (on sale now), should be here next week:
My lower radiator pipe has the plug in the casting (is this 3/4" pipe, I measured it looks like it?). The thermostat housing has two plates (see pic). Was going to make an new plate with a hose stem and replace it so I can hook up hose. Is there a difference on which plate? One does look just slightly smaller. Both appear to be below the thermostat, so it would recirc. heated water in the block & head, not radiator.
Any thoughts appreciated - It takes too long to get her started on just the pony. Thanks. Bob
