45 miles south spingfield il. | the radiator on 1660's had stagered tubes very hard to clean or keep clean. put trouble light behind radiator look from other side you'll see what I mean. If thecore is blocked very little dust is neede to plug. When clean lots of dust will go right through [ once saw 9500jd pass through that was cutting to slow, Grin] If that doesn't help or if it does you still have a leak that is letting dirt through. Oh by the way while checking your belt wiggle the fan, make sure bearing is good - nasty when it lets go. Good luck |
