I'm running Pentosin in my system and noticed something white with a blue tint to it in the system. I took the blocks apart they were coated this stuff, a thin coat. What would cause this? Was it because i had too much pentosin it or something else? How do I clean the radiator anyways?
 
I'm assuming you only have copper in your loop?

This is normal if you didn't clean out your parts before putting them in the loop, or it's a breakdown of the tubing by the pentosin.

Fairly normal, and why I'd never use more than 5% pentosin in my loop, personally.
 
Yes, it is all copper. I'll guess i'll clean the stuff later on. All the parts were clean before I put the system together. I took it apart to install the new setup. Will this affect cooling?
 
You may need to re-clean the loop again. Drain the cooling loop and add a good cleaning mixture of 50% Distilled Vinegar + 50% Distilled Water. Run for about 20 mins. Drain, and refill with your preferred coolant mixture.
