Title: Honda ST1100 HOSES, OIL COOLER (A and B)
Post by: Garry_Coates on September 06, 2022, 07:14:16 PM

I am planning some trips this summer and have ordered OEM radiator hoses, seals and o-rings from Honda. Unfortunatley the oil cooler hoses A and B are no longer available. These hoses are used on all STs up to 1995. After that nothing on the parts list.

Part numbers:  19520-MT3-000 and 19525-MT3-000

Does anybody remember what aftermarket hoses they used? Specifications (ID, OD) would be useful. In an emergency can they be blocked off like in later models?

Regards

Please note that 19525-MT3-000 is still available from David Silver. Once I have this I will source an alternative for 19520-MT3-000.

Feedback for future reference: These hoses ID=6.3mm OD=13.3mm.

HOSE, OIL COOLER (B) 19525-MT3-000 looks to be the right shape to also replace HOSE, OIL COOLER (A) 19520-MT3-000 once it has been shortened.

The alternative is Gates heater hose part number 28407. Best buy 1 metre for two hoses to allow for the bend.
