Looking to install a block heater for my 2000 Chevy Blazer LT, 4DR, 4X4. Need to figure out which freeze plug i should install it in. Which side of the engine and location of the freeze plug? Pics if possible. Thanks.

 

You're in luck. I've attached the scans from my 1999 manual that shows how to replace a block heater. I scanned them thinking I was going to remove it as a way to drain the block. I ended up not doing it but perhaps the scans will help.

Be sure to report back how it goes.
