Cooling System Leak - Is It Repairable

[Okie2ee]

My cooling manifold where the drain valve is located is leaking a small amount at the Drain Valve and also leaking a little where the manifold goes into the block................I assume the block fit up is with a o-ring and can be replaced but not sure about the Drain Valve leaking.............haven't removed it yet but was wondering if it has an o-ring that also may be leaking..............thanks

The O-ring for the drain cock is not shown separately, you may need to disassemble to see if you can match it to a generic one. Maybe try that selection from HFT, I think it's called, 'Storehouse.'

On anything like that, a smear of plumber's stem grease may help to keep things supple and to effect a good seal. Make sure that you clean mating surfaces before introducing the new O-ring into the position it occupies.

JT had this recently, see below

I'm sure these will be generic o-rings that be be picked up for 30c, it's just a matter of knowing the size.... I don't suppose JT or anybody else measured one?

yes I ordered one of the number '30' o-ring as was advised to me on the thread link above, although my bike stopped leaking so I never fitted it
