Aftermarket Coolant/Radiator Hoses
Changed the coolant hoses on KLR#2 today. The lower rad hose had a lovely display of green beads on the ends of the reinforcement braids around the end of the hose. Pretty!
In case this is helpful to someone:
Three hoses which are all 3/4" inside diameter.
1) Waterpump to cylinder uses a relatively straight hose with 90 degree bend at the waterpump end. Goodyear #65009 works perfectly with a bit trimed from each end.
2) Lower radiator hose to waterpump uses a relatively straight length of 3/4" ID hose. Ordinary 3/4" heater hose does the job well.
3) Upper radiator hose to thermostat housing. 3/4" heater hose which requires internal support to prevent kinking of the hose, or molded hose to fit. Could not identify hose in stock and the equivalent to the Goodyear #63936 was not available. NB* the #63936 appears to be a longer version of the Goodyear #65009 so don't see that it would be particularly satisfactory, given only one tight bend. Haven't had one in hand, however.
What worked well is an old trick which is to slip a coil spring into the hose which prevents the hose's kinking over while not significantly affecting coolant flow. I slipped a pair of Dynaline #24856 3/4x .091 - 6 inch long springs (two per package) into the length of straight heater hose and all is well.
Hoses $18.91 including taxes + springs $8.38.
Hope this is useful to someone. Didn't buy Cow-a-suki because dealer is closed for 2 days + 2 more days for order and wanted to get it done. Also these hoses are heavier and better quality.
