Review on ✨ Efficient Engine Block Immersion Heater for Buick, Chevrolet, Oldsmobile, Pontiac, Belarus, John Deere, Kubota, Perkins, Massey Ferguson by Joseph Reed

This is a well made (made in the US) product, although I don't really like the electrical connector; works, but I would like something more reliable, especially when installed on a tractor. I took off a star because of the connection. This device has a 3/4" NPT thread, they also offer a device with a 1" thread. MAKE SURE YOU ARE BUYING THE RIGHT THING! Female from 3/4" to 1"; This is NOT recommended as it restricts the heater element's access to the coolant in the engine block. Basically, if you use this (3/4") version with the 1" socket, you lose a lot of heat output. Also, since the heating element is not actually surrounded by coolant, there is a risk of the device overheating. A quick guide: the Kubota B2601 has 1" threads, not 3/4". So the correct block for B2601 is Zerostart 310-0003, not THIS!
