Review on Actron SP0F000049 Bosch Style Line 2-Inch Electrical Water/Oil Temperature Gauge - Black Dial Face with Black Bezel by Paul Wall

My 1979 Viking had two OEM gauges on the handlebars that read 210F when the engines were running at operating temperature, while the old wet bulb gauges in the engine room read 175F. I installed these sensors and the temperature readings now match the correct 175F-180F across the four sensors. I love that 180F is in the middle of the range on the dial as that is my thermostat's target temperature. Great product at a reasonable price. Installation was plug n play, use only the temporary transmitters provided, they all come together as one package. Don't try to save installation time by using old senders. TBH, that's probably the problem anyway.
