Sinister Coolant Filtration

[Gary Burris]

I have recently installed the sinister coolant filtration system. I flushed the system as much as possible and added Cat ELC Coolant. I was wondering what everyone has seen on how often they needed to change out the coolant filter.

I change mine every other oil change, along with fuel filters. Everytime I cut mine open to take a look and it is full of casting sand.

How much junk collects in your filters? I only have 39k on my truck so I decided to keep the gold coolant in with the filter system installed. I'll be changing filters in the next couple of weeks...should be interesting to see what I get
