------ WARNING! ------

Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

----------------------

Replace the water temperature regulator (thermostat) on a regular basis in order to reduce the chance of unscheduled downtime and of problems with the cooling system.

The thermostat should be replaced after the cooling system has been cleaned. Replace the thermostat and replace the seals while the cooling system is completely drained or while the cooling system coolant is drained to a level that is below the thermostat housing.

Note: If you are only replacing the thermostat, drain the cooling system coolant to a level that is below the thermostat housing.


NOTICE

Failure to replace the engine's thermostat on a regularly scheduled basis could cause severe engine damage.
