Corsa dash in Monza = Temp sending unit?

[cnicol]

Changing gears just slightly. I have a 1966 Monza with a Corsa dash installed (in it when I bought the car) and it is a 1966 140 horse. There shouldn't have been a thermister there as the original gauges wouldn't have needed it. Right? My question is would I need to use the adaptor from Clark's on a 140 as well if it's not a Corsa? I have purchased a thermistor already courtesy of Mr. Nicol. At the present time all that works is the speedometer and it is pretty much spot on.

Craig replies: No adapter needed on 140 and turbo heads. These heads are built to accommodate the thermistor. I recommend installing them with a dash of anti-seize on the threads so the thermistor can be removed during cylinder head service.

Thanks Craig.

If the 140HP head has not been modified then the thermistor will fit. ALL 140HP heads had the threaded hole sized to the thermistor - also why the temp snap switch for the 140HP head is different. It was made to fit the threaded hole for the thermistor (thermistor on one head, snap switch on the other).
