Wanted to hear some opinions on coolant filters as a general proposition. The set-up I'm referring to is a spin-on type filter (looks like an oil filter) installed inline on a heater hose. I put one of these on my '68 Chevy P/U to deal with a continuous contamination problem. The 454 I installed came from a jet-boat and little did I know, the water jackets had layer upon layer of river silt deposits, and no amount of flushing would get rid of it. Got tired of flushing system every month and was too lazy to pull the motor, pop the freeze plugs etc., etc. Asked around a little and was referred to a "trucker" parts store. The guy there said he runs one of these filters on all of his vehicles for longevity. Not only does it filter the system, but the spin-on filter itself has a sort of timed release additive package that bolsters that of the coolant (which I guess diminishes over time). Well, it solved my silt problem and I'm wondering if it might be a good addition for an 80. It's an easy install, the whole set-up was under $30, the filters about $8. Your thoughts?
