Glow plugs and Injectors
My 7.3 Escursion has 128,000 on it and runs great and starts fine. When should I think about replacing the injectors and glow plugs? Also I do not have an engine heater and it is rough stating in the winter below 15 degrees. I have tried to find a dip stick type heater but cannot find one long engough. Have any suggestions? Thanks.
