Chery Tiggo. Manual — part 347
Inspection
1. Use special tool CH-10002 to disconnect the steer-
ing tie rod from the knuckle.
2. When the starting torque exceeds the standard
value, replace the steering tie rod end.
• Standard value: 0.98 - 3.92 N·m
3. When the starting torque is less than the standard
value, inspect the ball joint for excessive play or
wear problem. If there is no problem found, the ball
joint can be used.

GENERAL INFORMATION
Description
The power steering pump is a constant flow rate and displacement vane type pump. The pump reservoir is detached
from the pump body. The pump is connected to the steering gear by the pressure and return lines.
Operation
The power steering pump is mounted to the engine and driven by the engine accessory drive belt. Power steering
fluid enters the pump from the reservoir. The power steering fluid is then trapped between the pump vanes and
moved to the high-pressure side of the pump creating a flow of steering fluid. The restriction of this flow by the
steering gear creates the pressure that provides the steering assist.
CAUTION:
• Operating the power steering with a low steering fluid level will damage the power steering sys-
tem.
• Holding the steering wheel in the full lock position for more than 3 seconds will damage the
power steering system.
