I'm in the process of installing a FORD ICE Block Heater and have got to the point of screwing in the block heater. I will try to take pics to try to show how to do it.
The steps required are first remove ICE lower cover.
Remove three bolts from brace under exhaust system and remove.
Make 14mm allen socket for removing Freeze Plug
Remove freeze plug, big mess coolant draining out of block.
Loosen 7 nuts on exhaust manifold and remove two nuts from catalytic converter, tilt manifold up to make more room to
Screw in ICE Block Heater and attach power cord.
Reinstall all parts and fill coolant back in reservoir.
