MBE4000 APPLICATION AND INSTALLATION
Air handling may be poorer and the coolant in the top tank may be more agitated when a coolant
recovery system is used.
Perform the necessary tests to determine whether the cooling system design provides adequate
expansion, drawdown, and deaeration volume in the radiator or remote top tanks.

COLD WEATHER OPERATING OPTIMIZATION
Newer fuel ef
fi
cient engines transfer less heat to the coolant; thus, it is important to maintain
proper coolant temperatures for optimum engine and heater performance, especially during severe
cold ambient operation. The following guidelines are given to maximize the available heat energy.
Engine
To maximize the available heat energy of the engine:
□
Increase idle speed
□
Avoid long term idle and/or light load operation (maintain minimum exhaust temperature)
□
Use under hood air intake for engine (cold weather only)
Vehicle
To maximize the available heat energy of the vehicle:
□
Use auxiliary heater
□
On/Off fan clutch
□
Auxiliary oil coolers
must not
be located in radiator outlet tank
□
Seal operator's compartment interior to eliminate any direct cold outside air source
□
Consider full winterizing package for maximum comfort level
□
Thermal windows
□
Insulate walls, roofs,
fl
oors, doors, etc.
□
Reduce exposed interior metal surfaces
□
Auxiliary fuel
fi
red coolant heater
□
Install shutters only as a last effort
Cooling System
To maximize the available heat energy of the cooling system:
□
Use optimized Rapid Warm-up System
□
Set coolant antifreeze concentration correctly
