has anybody heard of a silent recall ar extended warranty on this problem? my '02 mxz renegade 700 has a hole in the antifreeze resevoir, it looks like it melted. the hole is on the engine side not the exhaust side. i've heard about some replacements of these under warranty but i've got 2600 miles and it's an '02. unfortunately for me the motor blew when it overheated. the temp. light never came on, is that cuz the antifreeze wasn't touching the sensor due to being low?
