S50 - coolant drain on block?

[funcrew]

Does the S50 have a coolant drain on the block like an M20 does?

[matt]

Yes, it's even in the same place.

i got a better question, where are you guys bleeding the cooling system when using m20(late) radiator w/ m/s50 motor? i been doing mine from the reservoir cap...

[FredK]

Yep, I just leave the reservoir cap open, turn the car on, max heat max fan, rev it for a while until I see the level of the coolant rise (takes a couple of mins), bring the revs back down, then shut the car off. I find the late M20 expansion tank already does a decent job filling most of the system since it is up so high, in comparison to the M42's built-in reservoir.
