fourjs Posted September 1, 2008 Report Posted September 1, 2008 2003 banshee, coolhead and new top end, new seals on lower, aftermarket impeller and gear is alright, had same jetting for years, nothing changed but some engine work everthing was fine for a couple of rides, until..... coolant started to overflow out the tube, let it cool down, took off cap and added some more coolant, started the engine, and within 3 seconds, out came the coolant from the radiator neck, a big ole surge of coolant came out, when leaving it to idle, it did this several more times, put new cap on, and all it would do is overflow out the tube, took it home, engine had 5 hours to cool down, added more coolant, and wham-o, same thing, like a big air pocket was in the radiator or something, it spits out evertime you add more coolant, did a search but could not find anyting like this. any idesa... thanks..... ..
