Re: Coolant filter
I flushed my coolant system before adding a filter. The first filter plugged up in less than a day. The second lasted another 2 days. The third one I'm not really sure because I didn't check it for a while but I ended up changing it about a month later. Its pretty amazing how much crud is floating around in there. Even when you think you have it clean. I now change mine every oil change.
I don't think its 100% necessary but they are nice to have. I would recommend trying it and seeing for yourself how much the filter will catch.
