I sure did... and that's the $2,000 lesson I learned.

The sending unit sets on top of the head and extends down into the coolant. The infrared thermometer can tell you the temperature of the nut that holds the sending unit, but it really doesn't tell you the temperature of the coolant. So the nut can be at 200+ degrees, with the coolant at 180 degrees.

I will never forget that!!




When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car.
