Low coolant level warning - Engine overheating - DTC's evident Transaction No.: 2065919/5 Customer statement / workshop findings • Coolant leaking from the mechanical coolant pump Or • Coolant witness marks on the mechanical coolant pump although coolant is not leaking/dripping from the pump Or • Low coolant level warning displayed within the DIP Or • Engine overheating issues and/or DTC P218100: Cooling System Performance with symptom code 8113 CAUTION: In the event that DTC P218100: Cooling System Performance with symptom code 8113 is evident Or • Air in the coolant DTC’s (various) are evident The operative should also refer to TPI 2051893/- Technical background Revision history TPI 2065919/5 - Revised instructions to include the replacement the Solenoid for coolant circuit N492 (Figure 1 ARROW) in conjunction with the mechanical coolant pump Figure 1 HINT: The operative MUST ensure the instructions within the Measure section are followed, the instructions differ slightly depending on the mechanical coolant pump part number (B or C suffix) Production change The following mechanical coolant pump part numbers are affected: • 07P 121 008B • 07P 121 008C INTERNAL VERY IMPORTANT: • In the event a B level mechanical coolant pump is fitted and a replacement pump is required a non technical DISS query is required • In the event a C level mechanical coolant pump is fitted and a replacement coolant pump is required a technical DISS query is required to request permission from Product support before replacement Measure 07P 121 008B or 07P 121 008C mechanical coolant pump fitted The following should be conducted until instructed regardless of the mechanical coolant pump part number which is fitted 1) On receipt of the vehicle - Take a photograph of the coolant level within the coolant reservoir • Using ODIS check to confirm that no DTC’s are evident relating to low coolant or overheating issues in particular DTC P218100: Cooling System Performance with symptom code 8113 Or Air in the coolant DTC’s • Save the current ODIS log • Take a photo of any coolant related warnings which are evident within the DIP • Take a photo of any suspected coolant leaks 2) Referring to Rep.Gr 19 - Pressure test the coolant system to confirm if a coolant leak is evident from the mechanical coolant pump VERY IMPORTANT: In the event the mechanical coolant pump is leaking/dripping as a result of conducting the coolant pressure test - Record a clear video of the leak (whilst carrying out the pressure test) Refer to the video located within the Bentley Hub reference TPI 2065919/- this video shows an example of a coolant pump with no leak although there is a small coolant witness mark evident (Figure 2) in this scenario the coolant witness mark should be cleaned off (using a suitable cleaning agent) to the condition shown in Figure 3 Figure 2 INTERNAL Figure 3 In the event that coolant is not leaking from the mechanical coolant pump whilst conducting the pressure test the operative must conduct Step 3 (road test) to confirm if a coolant leak is evident or not However If a coolant leak is evident whilst conducting the pressure test the operative must go to Step 4 3) Conduct a road test • On return conduct a visual check to confirm if the leak is evident or not • Should the leak not be evident, no further action is required TIP: In the event there are no visible coolant leaks from the mechanical coolant pump and the coolant level is to specification as per Rep.Gr 10 DO NOT replace the mechanical coolant pump (No further action is required) However • If a visible coolant leak is evident the operative should continue with the remaining instructions from Step 4 4) Check to confirm the part number of the mechanical coolant pump NOTE: If 07P 121 008B is fitted - Conduct Steps 5 and 6 Or If 07P 121 008C is fitted the operative should conduct Steps 7 and 8 07P 121 008B coolant pump 5) Replace the following: • Mechanical coolant pump - Rep.Gr 19 • Solenoid for coolant circuit N492 assembly - Rep.Gr 19 - Use a Mityvac or similar vacuum tool to check and confirm there are no vacuum related issues/leaks present within the system once N492 has been replaced Ensure all procedures within the Repair manual are followed including any alignments/calibrations which are required (Dependi ng on vehicle specification) • In the event that 07P 121 008B was originally fitted and replaced with 07P 121 008C a non technical DISS query is required IMPORTANT: Ensure the vacuum hoses are free from moisture DO NOT use compressed air to attempt to remove moisture from the vacuum hoses (allow the moisture to naturally evaporate from the vacuum lines) as damage to other components and unintentional disconnection of vacuum hoses can occur if compressed air is used 6) Conduct a road test to confirm the issue is no longer evident INTERNAL 07P 121 008C coolant pump 7) Referring back to Figure 1 - Disconnect each vacuum hose with care from the Solenoid for coolant circuit N492 - visually monitor for any traces of coolant HINT: Refer to the video on the Bentley Hub referencing TPI 2061369/- to check for any signs of coolant within the vacuum hoses VERY IMPORTANT: If traces of coolant are evident during disconnection, take clear photos or record a clear video of any coolant within the vacuum hoses or N492 and attach to a new or existing technical DISS query Please note the quoted video should be used for reference purposes only as it may not show the same part which is fitted to the applicable vehicles (although the symptom is the same regardless of the type shown) • Use a Mityvac or similar vacuum tool to check and confirm there are no vacuum related issues/leaks present within the system to check and confirm if N492 is sticking open and supplying a constant vacuum • The operative must raise a technical DISS query or respond via an already open DISS query to request permission to replace the mechanical coolant pump ensuring the following is attached to the DISS query: • Clear photo of the coolant level • Clear photo of the original mechanical coolant pump part number 07P 121 008C (Figure 4) • Video of the coolant leak whilst carrying out the pressure test • Current ODIS log NOTE: The photo shown in Figure 4 is a C level coolant pump (shown removed from the vehicle for photographic purposes) a borescope may have to be used for photos of the coolant pump when fitted Figure 4 INTERNAL • Once permission has been given via the technical DISS query, replace the following • Mechanical coolant pump - Rep.Gr 19 • Solenoid for coolant circuit N492 assembly - Rep.Gr 19 IMPORTANT: Ensure the vacuum hoses are free from moisture DO NOT use compressed air to attempt to remove moisture from the vacuum hoses (allow the moisture to naturally evaporate from the vacuum lines) as damage to other components and unintentional disconnection of vacuum hoses can occur if compressed air is used Ensure all procedures within the Repair manual are followed including any alignments/calibrations which are required (Dependi ng on vehicle specification) NOTE: Do not discard the mechanical coolant pump (07P 121 008C or N492) as they may be requested for analysis 8) Conduct a road test to confirm the issue is no longer evident Warranty accounting instructions Warranty Type Damage Service Number Damage Code Coolant pressure test Labour Operation Code Time Road test Labour Operation Code Time 110 or 910 19 50 00 50 19 01 01 00 10 TU 01 21 00 00 50 TU Bentayga Time to replace the mechanical coolant pump and N492 assembly Labour Operation Code 19 50 19 51 (Use 99 index until 16/02/23) Time 70 TU Time to remove and refit the front end module Labour Operation Code 50 38 19 00 Time 760 TU New Continental GT/C Time to replace the mechanical coolant pump and N942 assembly Labour Operation Code 19 50 19 01 (Use 99 index until 16/02/23) Time 250 TU New Flying Spur Time to replace the mechanical coolant pump and N942 assembly Labour Operation Code 19 50 19 00 (Use 99 index until 16/02/23) Time 210 TU Parts information Refer to the ETKA parts catalogue INTERNAL
