I bought the PRL coolant expansion tank and the sight glass isn't showing anything, it just has condensation on it. I filled it up checking the glass every so often and ended up over filling it because it showed nothing. Did I fill it wrong? Does any one here have some helpful tips or a good video I can learn from? I would hate to burn a perfectly good fl5.

I had the same issue with mine. Sent it in under warranty and they sent me a new one. The sight glass still doesnt work properly. I feel like that sight glass should be fuller.

I did run the one that doesn't work for a while and the temps were fine, but the sight glass doesnt work.

I contacted support and they agreed to refund me if I drilled a hole in the expansion tank. Never got either of the 2 tanks working properly. I have the stock tank now.

I try to loosen the nut of the sight class.

This is grand. I thought I was going to get this to replace my Radium tank since the sight tube isn’t accurate either. 😂
