7. COOLING SYSTEM
Coolant reservoir
Water pump assembly
The water pump is driven by the engine drive belt and supplies
the coolant to each area of the engine.
Thermostat assembly
When the engine coolant
reaches 90˚C, the
thermostat starts to open (fully
open at 100˚C) and lets the
coolant flow to the radiator to
maintain the engine
temperature.

1) Drive Belt
Overview ▶
There are two types of belt system; EPS (Electric Power Steering) and HPS (Hydraulic Power Steering).
In the vehicle with ESP, instead of power steering pulley, the idle pulley is installed on the engine.
The belt system is a single belt drive system which uses single V-belt with 6 grooves. This design
provides the long life span and minimizes the belt slip and noise.

2) Hydraulic Tensioner Assembly
The hydraulic tensioner maintains the belt tension to minimize the slip and vibration and provides long
life span of the belt. Hydraulic tensioner consists of hydraulic tension spring, hydraulic damper, lever arm
and tension pulley.
To transfer the tension to the belt from the hydraulic tensioner in small working space in G20DF engine,
the belt system uses the longer lever arm.Overview ▶

3) Crankshaft Pulley (CRS)
The strut type tensioner automatically adjusts the belt tension to provide the reliability and durability for
the system. And, the belt tension is decreased to minimize the friction loss and improve the belt
operating noise.Overview ▶
