Aftermarket Mechanical Temp Gauge Hookup Location

[dmsfrr]

Yes the CVR for the gauges may be failing or has already failed.


The only(?) drawback to that spot on the water pump is it's the inlet to the engine from the radiator... so it will always indicate 20 or as much as 30 degrees cooler than the coolant temperature in the engine. Even lower / worse if the thermostat happens to stick shut or the radiator is obstructed.

It's not necessarily a 'bad' place to locate the sensor, just something to be aware of.
