My 03 Rincon is leaking coolant from a small hose that is connected on the bottom of the thermostat housing. I cannot find where it goes to I havent noticed this problem before and i dont know if something else might be wrong if anyone has had this problem please help.

 

It sounds like you are talking about the water pump, not the thermostat. The thermostat is on top of the engine. There is a weep hose on the water pump. Is the little hose straight or does it have a bend in it? The 03 models had problems with the weep hose and they were replaced by the new bent style. I think they allowed dirt into the hose and messed up the seal. If this sounds like yours, you may need a new water pump. How bad is the leak?

 

it sounds like liquid cooling causes more problems than good .
