Chery A18. Manual — part 41

Note:

·Eccentricity between front silencer and the intake/exhaust hose is 18mm. Adjust front

silencer position in assembly to guarantee a gap between the front silencer and the
channel heat insulator more than 10mm.

·In assembly, hose clamp should not be aslant installed around the exhaust hose.

·Distance between the expanding section on exhaust hose and the section of hose

clamp should be 1～4mm in assembly.

⑦ Installation of exhaust hose bracket:

——

Install exhaust hose bracket.

——

Mount 4 M8 lock nuts and tighten them with a torque of 12±1Nm.

2. Examine gas leakage in exhaust system connection and its adjustment method:

Examine leakage in exhaust system interface after engine warm-up. Certain amount of gas
leakage is permitted (but not permitted in interface between exhaust manifolds and front hose
assembly). It can be taken as a principle of no leakage if no engine wobble and no sound
like ’pu’, ’pu’ in interface heard. If the above phenomenon is found, loosen the hose clamp in
interface and rotate it a few circles, then tighten it again after adjusting installation direction
of hose clamp.

Installation of heat insulator

——

Install each heat insulators to its proper position, and then tighten the clip.

FUEL SYSTEM

ASSEMBLY AND DISASSEMBLY OF FUEL SYSTEM

Before repair procedure

Warning：

·Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage.

Always keep sparks and flames away from fuel.

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious

injuries or death and damage. Fuel can also irritate skin and eyes. To prevent
this, always complete the following “Fuel Line Safety Procedure”.

Fuel Line Safety Procedure

Note

·Fuel in the fuel system is under high pressure also when the engine is not

running.

1．Remove the fuel-filler cap and release the pressure in the fuel tank.

2．Remove the fuel pump relay.

3．Start the engine.

4．After the engine stalls, crank the engine several times.

5．Turn the ignition switch to LOCK position.

6．

Install the fuel pump relay.

After repair procedure

Warning：

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious

injuries or death and damage. When installing the fuel hose, observe“Fuel
Leakage Inspection” described below.

Fuel Leakage Inspection

Warning：

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious

injuries or death and damage. Always carry out the following procedure with the
engine stopped.

Caution：

·Connecting the wrong check connector terminal may possibly cause malfunction.

Carefully connect the specified terminal only.

1．Short the check connector terminal F/P body GND using a jumper wire.

2．Turn the ignition switch to ON position to operate the fuel pump.

3．Pressurize the system in this way for at least 5minites to be sure of no leakage.

·If there is fuel leakage, inspect the fuel hose, hose clamps, and fuel pipe sealing surface,

and replace as necessary.

4．After repair, assemble the system and repeat Steps 1 to 3.

Fuel tank removal/installation

Warning：

·Repair a fuel tank that has not been properly steam cleaned can be dangerous.

Explosion or fire may cause death or serious injury. Always properly steam clean
a fuel tank before repairing it.

·Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious

injuries or death and damage. Fuel can also irritate skin and eyes. To prevent
this, do not damage the sealing surface of the fuel pump until when removing or
installing.

Caution

·Disconnecting/connecting the quick release connector without cleaning it may

possibly cause damage to the fuel pipe and quick release connector. Always clean
the quick release connector joint area before disconnecting/connecting using a
cloth or soft brush, and make sure that it is free of foreign material.

1．Lever the vehicle.

2．Complete the “Before repair procedure”

3．Disconnect the negative battery cable.

4．Remove the fuel pump unit.

5．Siphon the fuel from the fuel tank.

6．Remove the middle pipe.

7．Remove in the order indicated in the table.

8．Install in the reverse order of removal.

9．

Complete the “After repair procedure”.

Installation of fuel case assembly:

——

Install fuel tank assembly.

——

Install 2 tapping screws (M6) on fuel tank

mouth.

——

Set up 3 fuel tank fixed belts and 5 M8 bolts.

——

Tighten 5 M8 bolts (tightening torque is 30±
3Nm) and 2 tapping screws (tightening torque
is 4±0.5Nm).

——

Install fuel mouth cap and steel wire stopper.

——

Connect import and export tube on fuel tank,
clamp tube lock hoop by special tool.

Note: In assembly, clearance between fuel tank

assembly and back wheel cover inner
board should be more than 12mm.

Assembly and disassembly of fuel rail and fuel

injector:

——

Disassemble import tube lock hoop of fuel

rail. Remove injector plug.

——

Unscrew two root bolts under fuel rail. Take
out fuel rail and injector by carefully shaking
upwards.

——

Pull out fuel injector by rotating it. Replace

pad when re-install.

Pay attention to right position in assembly, and

take care of the pad.

area

before

disconnecting / connecting using a cloth or a
soft brush, and make sure that it is free of
foreign material.
