Sending unit in cylinder head
Hello, my aftermarket sending unit is inaccurate with my stock gauge because of the difference in resistances. I have the correct one now and I don’t want to make a mess with all the antifreeze in the block. What is the best way to put this sender in the head and catch some of the antifreeze? Take a drain plug off the block or let the radiator drain?
