The vacuum nipple on the 13B-RE's thermostat, what should I do with that? Should I just hook it up to a vacuum line? I want to use the stock double thermostat that came with it.

I don't have a photo, but it's the stock 13B-RE Cosmo waterpump assembly. I guess I'm just wondering how it works considering it has 2 thermostats. Should I just leave it as is?

 

I removed my thermostats and pluged the nipple

 

if i remember right when under vacuum the rear (cooler) stat is blocked
as soon as boost is present the valve opens and allows flow.
I had it hooked up on the 20b but ended up taking the hose off allowing
flow all the time through the cooler stat.

Well, I guess I'll just leave the vacuum nipple open then. Unless someone thinks that I should just hook up a vacuum line to it that is....
