Just so you guys know, I have searched through 10 pages and couldn't find my answer lol. I am getting ready to do a DIY coolant filter system( my wifes car dealership has everything laying around so I'm getting it for free! ). My question is.....what is the recommended filter replacement time on a coolant filter? Like every oil change or what?

Thanks

Chad

The 1st change is pretty quick as in 1k miles. Then maybe 3k and then at oil changes. The miles after you 1st install it its catching alot of crud.
The fail safe way is to put your hand on the filter when the truck is hot.
Hot coolant filter means its still working.
A filter that is not warm/hot means its clogged up and the coolant is bypassing

Most companies that build and sell the kits state change filter every 3 months for 9 months, then once a year after that. After 3 months, I had a fair amount of crud laying in the bottom of the filter, but still had good circulation. A cool little feature if your building your own DIY kit, install an inline fuel flow screen filter (normally found on quads/bikes/jetskis) and you can monitor how much return flow you have.

Install a couple of valves to shut the flow off web your ready to change it as well so you don't lose any.

Definitely will help will longevity, heres a few pics I snapped when I changed my filter for the first time. This is what was just floating in the filter body itself, I assume the filter would retain majority of the particles.

This was Bob's recomendation for filter changes at Dieselsite. Recommendations on filter changes:
Use one filter every three months for the first nine months after installation. The lack of flow into the expansion tank is an indication that your filter is plugged. Change the filter if it should plug before the 3-month interval. After the 4th filter is installed your filter should be changed once per year.
I was limited timewise plus living out in the country far from any parts houses, I got Dieselsites kit, great investment IMO.

I'm good on having someone else build it, I know adam is good but I want this to be my little project.....its simple and won't take too long.
