Just wondering what is the best place to mount engine temperature warning sensor on M25-XP Universal? Oil temperature in oil pan maybe? I have access to different sensors (normally open) mounted on 1/4 , 3/8 and 1/2 NPT. Also at what temperature should I set the sensor to give warning of any overheating. The manual states that nominal operating temp is 175-190 F (80-88 deg C). I'm planning to install both visual and sound overheating warning as I don't want to go thru repair ever again. Thanks for any suggestions.
