POWERTECH ENGINES - A NEW COOLING PHILOSOPHY

Meeting emission regulations with high quality performance requires a very efficient cooling system.
This has been achieved efficiently with the new PowerTech engines, where excellent heat dissipation promotes an optimised complete combustion.
COOLING PROMOTION BY DESIGN
. Cylinder block with water manifold on the cool side of the engine
. Crossflow design
. Wet cylinder liners
POSITIVE COOLING
. Large Radiator
. 600mm viscous fan with specially designed blades
. Collar fan design
. Closed cooling system
. Dual Temperature Cooling system
. High capacity plate-type oil cooler
. High capacity water pump
. Piston spray cooling
DUAL TEMPERATURE COOLING SYSTEM
To improve the cooling capacity of the PowerTech engines and reduce fuel consumption, John Deereintroduces the revolutionary Dual Temperature Cooling system.
This feature of the 6020 series tractors provides a large sized main radiator and centralised, maintenance free
heat exchangers giving highly efficient cooling and reducing maintenance time and cost.
INTEGRATED COOLING SYSTEM WITH
POWRQUAD TRANSMISSIONS
The mechanical pump circulates the coolant from the High temperature section (engine coolant) of the
radiator and separates approx. 10 % and re-directs it to the low temperature section (transmission and inter cooler) where it is cooled down further.
SEPARATE COOLING SYSTEM WITH
AUTOPOWR TRANSMISSION An electrical pump is used to circulate the low
temperature coolant to the Charge Air Cooler and the
Transmission/ Hydraulic Oil cooler.
