Default Mech gauge

Hi Rob....no, I have not tried a mechanical gauge as I do not know how and I have never seen a mechanical gauge that replaces a proper sending unit.

As previously mentioned, several times right after shut off I cracked the rad cap and quickly put in a temp gauge meant for fluid immersion and the temp is always at 155-160F.

Where can I get a mechanical gauge and where does it plug in?

Also, why would the average coolant temp rise from 130-140 F to 180-185 F after having the rad flushed, a thermostat installed and a new water pump?
