block heater for OC-3

[martinf]

Hi folks,

I'd like to install a block heater in the head of my OC-3, using one of the soft freeze plugs.  Anybody have any luck doing this?  I can't find a referenced one at my parts store and don't know if it will fit and which hole I should stick it in.

Any advice would be appreciated.

Look for a frost plug near the center of the block and as low as posible. Measure the diameter and check with your locol automotive parts store.  These frost plugs are usually a standard size and heaters should be readily available.

I knocked out the rear left freese plug and found that the heater needs to have the element point upwards at about 45 degrees.
