S2 K Series - Bleed Screw

[Caligarinet]

Anyone know what size the engine side coolant bleed screw is? (S2 K Series) or where to source one?

In a rush this morning, had to bleed some air out of the system and lost the bolt!!

managed to find a short capped head bolt to block the hole, but don’t want to torque up in case it’s too long and I strip the threads. 

Thanks

Go on then ... M6x1.0x how long?

[Caligarinet]

I’d say M5x1.0x10 as an estimate.

trying to find a tapered head M5 bolt and an M5 copper washer was proving difficult, so glad she found the original
