Audi Water Pump/Thermostat Kit - Genuine Audi 06M121013GKT2

Audi Water Pump & Thermostat Kit

ATTENTION!

This kit was created to replace your faulty 6-bolt designed water pump. If your vehicle features a water pump designed with 4 bolts, it is essential to install the conversion kit FIRST, which is available HERE!. It is important to install the conversion kit first, because the newly designed water pump now features 6-bolts and will require an updated pulley, which is included in the conversion kit.

For those who are performing this repair, it is crucial to verify the condition of the vacuum system before reinstallation of the Engine Water Pump. In some cases, some may experience Coolant Migration which can potentially make its way from the vacuum port on the water pump all the way to the turbocharger wastegate actuators, vacuum reservoir, vacuum pump, etc. There are 4 known points of inspection / "Checkpoints" we advise you follow to verify the extent of coolant migration. Things to look out for are areas with visible coolant (liquid) and/or coolant residue (white/pink in color showing coolant was present then had evaporated).

Inspection/Checkpoint Flow Chart:

Checkpoint 1 - Vacuum Line to N649 Valve (Mechanical Coolant Pump Switch Valve)

• IF YES - We recommend replacing the N649 Valve (see below) and continuing the inspection.
• IF NO - This Water Pump & Thermostat Kit is all that is needed.

Checkpoint 2 - Vacuum Tee to N545 Valve (Cylinder Block Coolant Valve)

• IF YES - We recommend replacing the Vacuum Hose Assembly (see below) and continuing the inspection.
