well it finally seems like winter round me and tonight was pretty cold. i took the truck out bc they salted the roads (not putting my car though that again) let the truck deal with it . anyway. it just seemd like i couldnt get heat in the thing for nothing. well i just got back form driving 20 mins and a good lil highway drive. stoped at McD's for a snack. parked the truck and checked to see how the overflow tank was to see if im leaking or if it needed a fill. but the uper rad hose was warm. the radiator was like ice cold. so imthinking i should block some of this radiator off on cold days to get some heat. yeah or nah. never had this problem with the cougar or mustang. but the truck got a big old grill .
