I thought it might make coolant flushes easier if I installed one of those Peak or Prestone flush kits (that connect to a garden hose) in the heater hose, but I'm wondering if it won't work on a 95 Grand Marquis because of the lack of a radiator cap on top of the radiator where the coolant is supposed to drain out. I suppose I could pull the top hose on the radiator, but then the flushed coolant will flow out all over the engine. If I just pull the lower radiator hose, I won't get a very good flush. Thoughts?
