I am replacing a block heater, but found thagt the screw has been stripped. I am wondering what the purpose of the screw is, and if I can drill it out. Is it a set screw, or does it have a blind nut? Any info would be great!!

Has like a retainer on back that stretches across the hole to pull it in tight. Small bar like thing approx. 1/4" wide x 1" - 1-1/2" long. That screw is threaded into that retainer.When you buy new one you'll see what I mean. You may want to try a pair of pliers or vise grips on fitting for cord and try spinning it counterclockwise to see if things will loosen up at all. My main concern would be where that retainer will drop to, if it comes off.

talk with a service dealer and show them the photo
it is very possible that as it screws in with no wires attached that it is the place where a heater element would be fitted
freeze plugs ( welsh plugs ) are normally a hammer fit with no screw threads
You block heater is a heater that should be screwed into the engine block. Yes, it can leak. You might need a new one, or you might need only to replace the gasket on the old one. I'm in Florida, and I can't quite see the gasket from here! Whenever you remove the block heater, or even when it leaks, you will get air into your cooling system, and then the heater will not work well, if at all. Once you get the leaking block heater fixed, you will need to "bleed" the cooling system of that air. How you do that is to run the engine at a medium speed with the car heater turned on full blast, and watch the coolant level in the radiator. Be sure to keep the radiator full of coolant, and the water pump should pump the air out in about 5 minutes. Be blessed.,
small paraffin stove under the engine will help start it,but i have no idea where the heater is on the block ,i would imagine its fitted into a core plug hole about half way up the block but what side ??
There is no fuse on a block heater. It is an extension cord with a resistor (element) on the end (see photo. If it not working, the resistor (coil) has failed. A new block heater is required.
Before replacing, however, check the outlet and/or beaker the outlet is on to see if it has tripped.
I too live in s/e Michigan, and it was -19 this am. No block heater can keep up with these extreme temps.
Hi ryan, yes my friend the best bet is to drain the coolant,as for the block heater,not sure which side for the sonoma but basically it is a frost plug with and internal element attached to it,once you unplug the cord typically there will be a small screw to remove, use a small punch or whatever will work and pop one side to roll the block heater so you can remove it,simple my fried,by the way a new block heater will come with installation instructions :) have fun and good luck ryan take care.
