3. GUIDELINES ON ENGINE SERVICE
G20DF engine is for FF (Front Engine Front Drive) type vehicle. Therefore, there are some deferent
maintenance and repair works compared to the engine for FR (Front Engine Rear Drive) type vehicle.
For safe and correct works, you must observe the working procedures and instructions in this manual.
And, use the designated tools as follow:
: Power train mounting stand / Engine hanger / Engine stand / Heavy duty engine jack.
Cautions before service works ▶
G20DF engine is FF (Front Engine Front Drive) type engine, and the engine and transmission are
integrated in a same module. Remember that there are many differences compared to
conventional engine in FR (Front Engine Rear Drive) type SUV vehicle.
To remove the engine, use the dedicated equipments such as engine jack, transmission jack,
engine stand and engine crane (1 ton).
To prevent the engine from abruptly starting during service in engine compartment, never allow
anybody to stay in the vehicle.
Make sure to disconnect the negative (-) cable from the battery to prevent any damage to electric
systems.
Make sure to clean the working area and to prepare the necessary tools before service works.
Always place the ignition switch to OFF position if not required. Otherwise, there could be
unexpected damage to electric devices or personal injuries due to short-circuit..
To prevent the foreign material from entering into the fuel injection system, completely seal the
inlets of HP pump, fuel hoses and high pressure pipes.
Do not remove the engine while supporting the oil pan with a jack. -

Lifting up the vehicle ▶
Before lifting up the vehicle with a lift, correctly support the lifting points.
To prevent the vehicle from rolling down, put the chocks under the tires (when using a 4-post lift).
Make sure to support the correct lifting points (when using a 2-post lift). -

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.

02-8
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.
