How long to run coolant filter?

[tony97gt]

Recently installed a Sinister Coolant Filter to see if I have any sand in there before doing a flush. How long should I run the first filter before replacing it and tearing it open to check for sand?

I'm running mine for about 8,000-10,000 miles. I plan on cutting it open when I remove it.

I have about 3,000 more miles to go until the change.

Holy smokes I've had my truck about 10 months and haven't even put 5k yet.

I had 3 vehicles; now 2 and I still put about 16,000 on my truck last year. LOL

I even work in town. I go on a lot of trips though and the truck is really comfortable and gives me enough space to bring back tools, supplies, and furniture if I find a deal while I'm out of town.

I'd say run it at least 5,000 miles to allow for any debris in there to work it's way through the filter. You can go longer though. I usually change mine every 12-15K miles. Don't see too much debris anymore. These filters can hold quite a bit so there's no need to change them too frequently.

I change mine every year. If the filter is hot and the coolant is returning into the degas bottle the filter is not plugged and no need to change it yet.

Same here.

To clarify, the coolant is going to return to the degas whether or not the filter is plugged or not. It's a bypass system... not inline. You can feel the lines under the truck after it's been running and if one is hot and the other isn't as hot, it's probably clogged.

I think after this initial filter run, I'll probably change it once a year as well.

Just installed my custom coolant filter on sunday. Gonna give it 500 or so miles/kms til I change it. Might take me a while as I dont drive my own vehicle much during winter.

I'd give it more than 500 miles Clayton. This is a lot of fluid (8 gallons) not being directly routed to that filter (it's on an alternate flow route). It's going to take a lot of time for it to make its way through the filter.
