Check it periodically by holding your hand on the filter. When it gets plugged up and no longer flows coolant, it will not be hot. My first filter plugged up in about a month, the second took about three months and my current filter has been there for several years now. I use an IR thermometer these days to check filter temp and compare it to water pump temp. Since they are pretty close, I know it is still flowing coolant. Since this is a bypass filter, there is no harm done when it plugs up and stops flowing.

I got a coolant filter from diesel site and I was wondering how often the filter needed changed.
When it plugs up, 50,000 miles, 1,000 hours, or 1 year. There are also some long life filters available. They are rated for 150,000 miles. I don't know what the time interval is for the long life ones.
If only those who knew what they were talking about replied, this thread would still be on page one.
