Application: This involves removing a freeze plug from your
engine block, and replacing it with a block heater. The heater shown
replaces a 1-1/2 inch freeze plug, and should work on any 1990-2000 Ford
Ranger 4.0L OHV engine, as well as the 3.0L and 2.3L with a
1-1/2" freeze plug.
Hey guys, so as my truck
came from California, and here in Saskatoon its gets to -50 Celsius, I
figured I'd put a block heater in. I didn't see a DIY anywhere so I
decided to make one.
First things first, remove
the air box assembly.
Then, remove the inner
fender. Honestly, this was the hardest part of the job, haha.
Here you can see the freeze
plug you have to remove.
Now, before you remove it,
open your rad cap (make sure the engine isnt boiling hot) and then drain
the coolant via the lower radiator hose...this makes a big mess.
Then, take a punch or screw
driver, and beat in the edge of the freeze plug. Afterwards, just haul
it out with a set of pliers.
After the last of the
coolant has spewed out, give it a wipe clean, and grab your block
heater. Here is the Motorcraft one I bought from ford for 35$
Note: Nathan
couldn't recall the Motorcraft part number. Others have used the Kats
11416 Engine Block Heater:
Now, take a little bit of
NON-petroleum based grease and lube up the o-ring.
Take it, press it into the
hole, make sure its seated in the whole way around. Tighten the
screw...this opens up the wing nut and makes sure the plug stays in
place.
Then plug the end of the
cord in and run it through the grille or where ever you like. Put the
inner fender back, and then the air box.
Make sure to refill the radiator
until full, turn on the engine, and let it run WITHOUT the cap on in
order to get some of the air out. Top up and then you're ready to go.
