OK, so those are like the magic pellets for the Northstar motors?

In that case, I'll withdraw my objection and just stay cautiously skeptical.

 

Yup that's exactly what they are. Don't get me wrong I am still skeptical and ready for some larger problem to rear it's ugly head at some very inconvenient moment, but hell, so far they have worked wonders for my magical coolant disappearing act, and if these little guys are just a little hidden gem that could potentially be an engine saver, then I'm all for it.

I'm not at hater. Ive carried a bottle of BG's coolant system sealer in my Rover incase I'm out and somthings goes wrong. Never used it, but its there. If it works it works. I'm changing to Peak LifeTime this summer..when I feel like getting coolant on me again. Ugg
Today I'm going to finally hook up my LR Rover driving lights so I'm not longer a poser.

 

Every time I have flushed my coolant, I have used the BG sealer, along with the BG super cool. The BG sealer just remains in suspension in the coolant, not clogging anything up, unless air is introducted in the form of a leak.
