Perkins 403EA-11, Operation And Maintenance Manual, Page: 27 / 114

Coolant from the bottom of the radiator passes
through the belt driven centrifugal water pump. The
coolant is cooled by the radiator and the temperature
is regulated by a water temperature regulator.
Engine efficiency, efficiency of emission controls, and
engine performance depend on adherence to proper
operation and maintenance recommendations.
Engine performance and efficiency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to this Operation and Maintenance
Manual, “Maintenance Interval Schedule” for more
information on maintenance items.
The 403EA-11T Turbocharged and 403EA-22T
Turbocharged engines have a closed crankcase
breather system installed. The crankcase breather
gases are part of the engines measured emissions
output. Any tampering with the closed crankcase
breather system could invalidate the engines
emissions compliance.
