I've noticed I have a small antifreeze leak where the block heater is installed in the back drivers side of the engine. Is this a pressed in freeze plug? or is this something threaded due to the heater. No matter what it looks like it will be a pain to repair.
Thx,

Which engine is in your truck?

 

ah, sorry

4.6

 

After looking at the 4.6 in a service manual,it looks like the block heater does some how hook into where a freeze plug is.That is the only place I can see where it can go.I live in Florida so,we have no use for block heaters here.
Be patient; someone will chime in soon.If not,go to this Ford website;it is run by Ford techs;
