Engine Block Heater
My friend has a 2003 F250 diesel. It has been unhappy about starting now that the temp is getting down around 20 deg. I would like to buy him an engine block heater for Christmas, but I am clueless. Any suggestions would be helpful. I called a couple of auto parts stores, they didn't have anything in stock but NAPA said they could order something. They had magnetically mounted & dip stick types. Do these work well? Can either method be left in/on, or do they need to be removed before drivng? I called the parts dept at the local Ford dealer. They can, of course, install a heater at a much greater cost. Any ideas?
