INNTECK Water Pump Rebuild Kit for KTM EXC 450, EXC 500, SXF 450 and HUSQVARNA FE 501 2013-2016

The INNTECK WY-821959 water pump rebuild kit is designed for KTM EXC 450, EXC 500, SXF 450 and HUSQVARNA FE 501 from 2013 to 2016. The water pump circulates the coolant. When its oil seal or bearing wears, coolant gets into the oil or leaks out of the weep hole: the engine overheats and the oil breaks down.
