Living in Montana and not having a garage can be tough on my Jeep in the winters. There have been a couple times it was cold enough that it didn’t want to start. I’ve been wanting to install a block heater since last summer, but I could never find instruction to do so. I had it in the shop for a couple days and asked how much they would charge to install it and they said $260 because they have to install it behind the ac compressor. So that gave me a start on where to install it.
THIS IS WHERE THE HEATER GOES
WHAT YOU WILL NEED:
-Napa engine block heater
-Synthetic grease that is thermally conductive
(I used brake lubricant advised by NAPA)
-1/2 breaker bar
-1/2 or 3/8 ratchet
-13mm socket
-13mm ratchet wrench
-21mm socket
-vise grips
-The screw I used to tack the heater to the block was a 1/4inch Phillips head (I don’t know the thread size)
INSTRUCTIONS:
1) To make things easier to reach, remove the track bar bolt at the frame. Then just move the track bar down and out of the way.
2) With the 1/2 breaker bar, loosen the serpentine belt tensioner and remove the belt from the ac compressor pulley.
3) Using a 13mm socket and 13mm ratchet wrench, take off the 4 ac compressor bolts. The ac compressor will not fall, it will just hang there.
Note: I had a second set of hands to pull the ac compressor up while I installed the heater.
4) Find the hole for the heater and make sure it’s clean of debris.
5) Smear grease on the heater.
6) Tighten the screw down that mounts the heater in place.
7) Reinstall the ac compressor and serpentine belt.
8) Route the cord to your preferred location. I chose to route the cord to my winch, so I can tuck the plug under the winch cover.
