I have a '94 XLT SP. I keep losing coolant out of the filler cap. I replaced the filler neck, filter, and flushed/filled system. The cap was new last season (only a few rides old!). I ran the sled to get good and warm, bled all the air out, and no leaks! However, after I shut it off, I lifted the back to inspect track, etc., and out comes coolant!! Last year I had to ride stopping every half-hour to refill to keep from blowing. I am very discouraged about this. Can anyone HELP?!
