It also serves to reduce wear... little debris that is too small to clog gets pushed through constantly ans slowly eats away at things like the water pump impeller.
They make coolant filter kits, but a brilliant man on another forum (goes by JetJock and he's frighteningly brilliant) pointed out that all you need is a water/fuel separation mount (it's a boating thing.
) and a coolant filter; They both use the same head and that mount is less expensive. Then you just get some additional hose and run the line that goes to the throttle body through the filter too. Replace the filter after you flush your coolant (once a year or so). A remote oil filter mount and an oil filter will work too (make sure there's no drain back valve in the filter), but the coolant filter is built a little differently to suit the task better.
