I have an 85 F250 and am living in Colorado. With the cold winters I am hesitant to use my block heater until I am sure that my block is not one of the ones prone to cracking. First does anyone know how I can check my serial number to see if it is safe and does anyone have experience with lower radiator hose heaters(im thinking of installing one until I know what block I have). Thanks For the Help.
