How do you replace the block heater cord on a 1990 Mercury Topaz?

If its just the cord, then follow the old cord to the back side of the engine ( really the side of the engine closest to the firewall ) and replace it. When the engine is cold, plug it in and you will hear the block heater heating up. If you don't hear anything, then replace the heater also. That requires a little more knowledge.
