I have a 67 mustang coupe with 289. I have a new aftermarket temp guage that reads numerically. I just installed a new cooling components electric fan, with this fan came a temp sending unit to tell the fan when to come on. I noticed that the temp Guage doesn't work on this new sending unit that came with the fan. My question is, can I put the old sending unit, in the hole on the thermostat housing? I understand that it is in front of the thermostat.
