I searched the archive and turned up no results on this. Lots of other good reading that set me back about an hour and a half, but not this.

for a 1972 240Z what size is the heater hose that attaches to the heater core - the one that branches off above the oil filter, just before the reducer hose.

Thanks!!

I just used 5/8'' gates heater hose. allow enough hose so you don't kink it. Gary

Thanks, Gary! Exactly what I needed to know.
