For so of us older guys we recall the simple days as I refer to them. There was green coolant,not 15 different types and colors, oil came in cardboard and tin top quart cans, a battery didnt cost $250+. You pulled the family camp trailer with a LTD station wagon with fake wood paneling on the sides, a truck was made to be hosed out when grubby. This all came to mind again this AM as I looked for a fan clutch for my 2000 Silverado. A half dozen mfg's, depends on its axle ratio, reverse rotation or normal rotation, A/C or no A/C, tow pkg or not, and finally the HD or "severe duty" version. Sheesh, maybe that screaming fan isnt so annoying after all.
