I’ll try to make this a quick recap. I bought a digital water temp gauge (18-255 degree) and sending unit from summit last year. The gauge started out fine (Week). Then the temp was all over the place, before settling on a max temp of 255 and never moving.
I decided to change the wiring harness, since it was on my list of thing to do and I knew it sucked.
The gauge still was stuck. I contacted summit who sent out a new gauge. However this gauge range read 22-375 degree.
Also found the sending unit was broken. For simplicity I grabbed a new one from autozone. The car now reads 140 cold (80 degree weather), 240 warm (should be about 190)
Summit is saying the gauges will sometimes go up that high. It’s normal. But my autozone sending unit is defective.
I have a feeling the temp sending unit has to mirror the gauge range to get an accurate reading and a gauge that reads 375 will never work with a sending unit built for a 255 gauge. Please help, I’m no expert
