Temperature gauge wasn't working-replaced thermostat with housing, dropped transmission and replaced metal tube through firewall. Heater works good, but has smell of leakage but find no spill or leak. Drove a distance and check gauge light went on and the temperature gauge was up, between normal and hot.

Good afternoon,

Did you do a pressure test for the leak?

What tube through the firewall? I do not know of any pipe that the transmission needs to be dropped to install.

My mechanic did a pressure test. There was a metal tube with rubber on both sides that he replaced that was behind. It had pin holes in it. He said he had to drop the transmission to get to it. I just drove it for thirty minutes with heater works on high and nothing happened-no overheat gauge or red light. It still smells.

Okay, if it smells it is leaking somewhere.

I would put some leak dye in the system. It will turn the coolant very bright green. If it is leaking, you will see it.
