LB7: Leaking block heater plug

[diesel53]

not sure why but my friends lb7 is leaking pretty bad from the block heater plug. Has anyone had this issue? Do they make a plug to replace that?? In az there is no point of having a block heater anyway

There is an o-ring that seals the block heater. Drain the coolant and loosen up the screw in the center. Remove the plug and match up an o-ring or replace the whole unit. You can also replace it with a freeze plug.
