grazapin Posted January 7, 2013 Report Share Posted January 7, 2013 This is a super basic question but I haven't found a definitive answer yet. In my '75 B210 what size(s) are the heater hoses? You'd think it would be listed in the shop manual but my old Clymer manual doesn't say. Most online parts houses show me bulk 5/8" hose, but Rockauto has that plus a 3/4" hose listed under heater hoses. The hoses in the car right now look smaller than the 5/8" I ordered, but that's just judging from outside diameter. I want to be sure I have the right size before I start pulling things apart since this is my daily driver. Quote Link to comment
ggzilla Posted January 7, 2013 Report Share Posted January 7, 2013 Generic 1/2" hose will work but doesn't fit through the grommets well. Nissan used thin-wall 13 mm hose. Quote Link to comment
grazapin Posted January 7, 2013 Author Report Share Posted January 7, 2013 Thanks ggzilla. That's bizarre that everywhere I've looked online has 5/8" and 3/4". That's a pretty big difference. I'm glad I didn't drain coolant and pull out the existing hoses today. Quote Link to comment
