Features
━━━━━━━━━━━━━━━━━━━━
✅ Coolpac Integrated Design
Complete with cooling package and air cleaner kit. Each component
specifically developed and rigorously tested for G-Drive products,
ensuring high performance, durability, and reliability.
✅ Large Capacity Aftercooler
Integral aftercoolers supplied with cooling water separate from the
engine jacket. Provides cooler, denser intake air for more complete
combustion, reduced engine stress, longer life and low exhaust
emissions.
✅ One Pump, Dual-Loop Cooling System
Engine jacket cooled by one radiator or heat exchanger; aftercoolers
cooled by a separate radiator or heat exchanger.
✅ High-Quality Pistons
Dual Ni-resist aluminium alloy pistons, ground and shaped to
compensate for thermal expansion – assuring a precise fit at all
normal operating temperatures.
✅ World-Class Service & Support
G-Drive products backed by an uncompromising level of technical
support and after sales service through a world class service network.
