Just purchased Block Heater Asy and Wire Asy. Heater Asy is a threaded asy. Where does it screw in?
Thanks

On the 7.3 Power Stroke it goes on the driver's side, low on the engine, right above the oil filter. It threads into the oil filter head where the oil cooler ends. Get under the truck, look up at the oil filter and you'll see the port just above it.

A few things that make it easier:
- The heater sits in coolant, so put a drain pan under the oil filter housing. Even with the radiator drained, there's coolant left in the block, and it will come out when you open that port. Have the heater ready so you can get it in fast.
- The heater element takes a 1-1/8 inch socket or wrench.
- Most people run the cord forward and leave the plug end behind the front bumper on the driver's side, near the tow hook. Keep it away from the exhaust and anything that moves.

Top the coolant back up afterward, then run the truck and check the fitting for leaks before you plug it in.
