Chevy 454 Temperature sending unit location on engine Luther 7-11-07  
I have a 1993 Coronado with a Chevy 454 engine. My temperature gauge does not rise above 100 degrees while running. I understand there is a separate sending unit for the dash gauge that has one lead from it. Can someone tell me where it is and how to test it?

Hi Michael,
Thanks for responding. I replaced my thermostat just before this problem started. I was told it was 93 or 94 or 95 degrees, I can't remember which. I replaced the sending unit that feed the computer but didn't find the other one. I will look again.
Thanks, Luther
