Care Point: Disconnect from oil pump only.

WARNING!
 
Possible fluid spills from vehicle systems during repairs or maintenance.
Risk of thermal incidents, slip hazards, corrosion of electrical components, failure of electrical or mechanical components or unwanted odours.
Always limit fluid spills and fully clean the spilled fluid after repairs or maintenance.

Install oil pump
1.   
Clean oil pump surfaces.
 

 
Care Point:
Make sure oil pump is clean and free from dirt and debris to avoid contamination.

Care Point:
Check all O-rings and replace if necessary.

 
2.   
Lubricate O-rings (11, 12).P80 THIX
 
3.   
Install new O-rings (11, 12).
 

4.   
Check plastic filters (13), replace if necessary.
 

 
Care Point:
O-rings can fall out of mating face of pump on assembly.

 
5.   
Check O-rings (11, 12) are in place.
 

 
Care Point:
Coupling is colour coded on the outer circumference. The alternator coupling colour code is blue.
Do not squeeze / deform the shape of the coupling prior to fitment. Care must be taken when handling and fitting the coupling. Deformation can cause damage to the internal structure and lead to premature part failure.
Make sure that the right coupling is being fitted to the correct vehicle system. The internal spline may be the same but the couplings are not interchangeable.
Renew coupling if the part has become damaged or deformed.

 
6.   
Check coupling (14) for wear or damage, replace if necessary.
 

7.   
Install pump alignment special tools (T5) in sequence (A, B).Oil pump alignment tool18 Nm
 

8.   
Install bolts (8).(M6x35) 10 Nm
 

9.   
Remove pump alignment tool (T5) in sequence (A, B).
 

10.  
Install shoulder bolts (9).(M8x40) 25 Nm
 
11.   
12.  
Install components in reverse order.
 
13.  
Check cooling system.
 
14.  
Check engine for leaks.
 
15.  
Read out and clear error memory.
