Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.

CAUTION:

• When removing water pump assembly, be careful not to get engine coolant on drive belt

• Water pump cannot be disassembled and should be replaced as a unit.

• After installing water pump, connect hose and clamp securely, then check for leaks using radiator cap tester.
