New esc water cooling nipples blocked

[lenny]

Hey just a heads up, Better check the esc nipples for blockages !
I have a brand new esc and it was blocked with silicone a lot,
Could not blow through it very much at all.
Took a small rod and push it through both nips, And than blow through it again.
I Can blow through it easy now.

Yes it suck,
It suck because the silicone can float around in the parts and get stuck any time.
Probably should take the hole thing a part and check every thing. RTR
