LJDB 103 Posted July 8, 2013 iv been looking at pictures of different engine bays and have noticed that some people are running 2 coolant temp sender units at the RHF of the head. what is the purose of them.i know 1 is the orginal for the coolant temp gauge. the only thing i can think of for another is a aftermarket coolant gauge aswell.
