My son's B4000 popped two freeze plugs recently (he just had water not coolant in the rad). Just by luck I found them laying in the carport and had him come right home.

He said the temp gauge didn't register hot so I'm suspecting a bad sending unit 'cause I can't imagine it not getting hot with two freeze plugs missing.

Sooo....
1) anybody know where the temp sending unit is, and
2) can I just reinstall the freeze plugs or is there a specific diagnostic/ installation process I ought to follow.

Thanks a million.
