Engine and accessories

▶

Engine has a lot of precise components. The specified tightening torque and correct procedures should

be kept during service works. And, the working area is always clean and well prepared.

When disassembling the engine, related parts (bolts, gaskets, etc.) should be stored as a set.

Carefully read the disassembly and reassembly procedures in this manual before starting the

works.

Clean the components completely with engine oil before assembling if needed.

Fully drain the engine oil, coolant and fuel from the vehicle and seal the inlets with the plugs before

removing the engine.

All the interference should be eliminated before removing the engine.

Tightening the fastener

▶

When reassembling the parts to G20DF, use the angle tightening as a final step.

1. Clean the mating surfaces before tightening.

2. Place the marks with paint to tighten by angle if the angle wrench is not available.

Exhaust system

▶

Wear the protective gloves before removing the exhaust pipe.

The exhaust pipe is very hot immediately after stopping th engine. Check if the exhaust pipe is fully

cooled down before servicing the exhaust system.

-

-

Cooling system

▶

Scalding hot coolant and steam could be blown out under pressure, which could cause serious

injury. Never remove the coolant reservoir cap when the engine and the radiator are hot.

-

The position and direction of the componets is based on the rear view.

Do not tighten the fasteners with excessive force. Especially, the threads of cylinder block could be

damaged.

The self screw bolt makes the thread itself when tightening it. Do not apply excessive force.

Do not reuse the bolt that has been tightened with angle tightening method.

Fuel and engine oil system

▶

The engine oil and fuel damages the painted surfaces and rubber material of the vehicle.

Disconnect the negative cable from the battery before servicing the fuel system, and prepare the

service plug grip.

When working with the fuel or oil systems in enclosed area, always keep the working area well-

ventilated and never allow anybody to smoke.

Do not allow the gasoline to contact to rubber or leather parts.

Carefully separate the pipe between high pressure fuel pump and fuel injector so that any fuel can

be spilled out.

Fully release the pressure from the fuel system before removing any parts of fuel system.

To release the fuel pressure in high pressure line, let the engine fully cool down.

Gaskets and seals on the fuel and oil systems should be replaced with new ones. All bolts and nuts

should be tightened as specified.

Prolonged exposure to the engine oil make cause a skin cancer or an irritation.

Used engine cotains the hazardous material that may cause the skin cancer. Do not allow the used

engine to make contact with your skin.

Make sure to wear the protection gloves and goggle when handling the engine oil. If contact

happens, rinse affected areas immediately with plenty of water. Do not wash it with gasoline or

solvent. If irritation persists, consult a doctor.

Improperly disposed engine oil can pollute the environment. Dispose the used engine oil and oil

filter in accordance with local environmental regulations.

Make sure to check the connections for leak after installation.

Electric devices

▶

To prevent any damage to electric systems, make sure to disconnect the negative (-) cable from the

battery and place the ignition switch to OFF position before servicing.

Use only the specified parts with same ratings when replacing the electric devices. Check the

grounds and connections for looseness.

-

-

Extraordinary care should be taken when servicing the electric systems. Currently, the engine uses a lot

of electric devices. Short circuit and poor contact may cause the low engine performance, incomplete

combustion and other abnormalities.

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.
