    Ordered one last fall and installed it this spring. However, it read apx 40* below actual and it took me a week to determine what was wrong (sensor vs gauge, wiring, engine temp). Amazon warranty replaced it and the new one solved the issue. Reads accurately in comparison to a laser thermometer checking temp at thermostat housing.
