I am looking for some information regarding the installation of an engine block heater on my 4025 2wd Mahindra. I purchased a 3/4 inch zerostart block heater from a dealer without good instructions on how to install. Is it possible the block heater goes into the metal cast with a 3/4 inch? plug that is between the two lower radiator hoses? Thanks for any help. Been a tough week as my block heater on my mahindra 6000 shorted out and was left without a tractor that would start.
