I was doing some research on block heaters and thanks to Andrew Caples work I found the part number but I couldn't find his FAQ. im stupid about freeze plugs and couldn't find how to or where to install them.
so here it is:
what need is ZEROSTART 3100055
it does fit on my non turbo 94, not sure of the fitment of the turbos, or different gens
Now on to the fun stuff:
There is a giant freeze plug on the front of the block between the bottom of the front head and the top of the exhaust manifold and next to the oil dipstick. that's where she will go.
1. Drain coolant
2.Remove freeze plug. use a punch, sturdy screwdriver, or extension. place it on the bottom edge of the freeze plug and give it a good tap. usually it will just pop out, but if it doesn't and you just make a hole use some needle nose pliers and grab it out.
3. Clean out the freeze plug hole.
4. Apply a thin layer of coolant, liquid soap, or silicon grease to heater o-ring. according to the instructions don't use petroleum based lubricant.
5. Insert heater into block. point the heater element in the correct position making sure the heater seats all the way up against the block.
6. tighten the screw to max torque of 2.26-2.82, do not over tighten.
7. refill coolant, start vehicle and check for leaks. don't forget to plug the cord into the heater.
8. enjoy a warm block every morning.
