I just recently bought a 69 SS396. The car has the standard SS dash, and a previous owner installed ( very tastefully ) a tach and mechanical oil/temp gauges at the bottom of the dash. The oil gauge works but the temp doesn't. Could the problem be the temp sending switch on the motor or something else? I'm not good with electrical and have no experience w. aftermarket gauges
. As usual, all help is appreciated.

Your in luck, the temp. gauge isn't electrical. The send unit transfers the heat from the block (or water) to the gauge. Wehre it expands a wound spring. The matterial just heats up & unwinds.

Your problem is one of three things. The sending unit in the block, the wire taht carries the heat is broken, the gauge is old and not a good brand.

Only bummer is these things are hard to do sepperate and usually comes as a kit.... So it's best to find the $15-$25 replacement that will match the oil unit.

If its a mechanical temp guage, it will have a tube filled with a gas running from the guage to the engine,instead of a wire which would indicate an electric guage..If you do have a mechanical guage, look for a kink or break in the tube. If the seal breaks it is worthless, as the gas escapes and the guage wont work.. I also had one of these fail on me after an engine overheated, didnt work again after that. I try to stick with electrical temp guages now.
