I find these to be good, effective devices. They do what they need to do.... They must be mounted low as indicated in the directions. They are heaters and expect them to get hot. I have two of this model for old tractors.

Much easier than a block heater install that requires punching out a freeze plug. Only complaint is that upon filling the radiator, coolant started pouring out of the seal between the heating element and the body. Factory installed the element crooked. Had to loosen the 4 bolts that hold the two halves together and draw the element in evenly to seal the two halves.

Installed no problem, cord length is long, heats the motor like a pro in negative temps.My only issue was the plug got damaged but I replaced it with an industrial strength clamp on style one.

Works great. Takes about 2 hours to heat up the block on a 1975 580B backhoe. Easy to install, seems to be very high quality.
