OE Number and Vehicle Verification
Use 074121005N as the first catalogue key, then confirm VM01017029 with the VOLKSWAGEN VIN and production date. An OE match alone is not sufficient when an engine family has mid-cycle changes.
Before approving VM01017029, enter 074121005N in the relevant VOLKSWAGEN parts catalogue. Check engine code, build period and any supersession notes returned by the VIN.
The workbook names TRANSPORTER as an application clue for 074121005N; vehicle-specific catalogue evidence still governs the final match.
Leak Prevention and Handling
Handle VM01017029 by its housing and protect the gasket face. Follow the specified tightening sequence for 074121005N, refill slowly and confirm heater circulation during bleeding.
Do not install 074121005N into a dirty circuit. Examine VM01017029, renew approved sealing parts and verify free rotation before the engine is started.
Supporting Stable Coolant Movement
The purpose of 074121005N on undefined vehicles is continuous coolant delivery. Stable flow reduces local hot spots and supports predictable thermostat and radiator operation.
Within the undefined cooling circuit, 074121005N drives coolant through passages, hoses and the radiator. Pump condition therefore affects temperature stability throughout a drive cycle.
B2B Procurement Notes
For a VOLKSWAGEN purchasing review, send 074121005N together with the required volume and shipping country. Quote VM01017029 when discussing carton marks or sample approval.
Wholesale enquiries should state 074121005N, VM01017029, order quantity and destination. VOLKSWAGEN distributors can also request neutral packing, label review and a pre-production sample.
Component Interface Verification
Check 074121005N for the correct impeller side, bearing hub and housing geometry. On VM01017029, even a small offset at the gasket surface can prevent a dependable seal.
Place the original unit and VM01017029 in the same orientation. Verify that 074121005N shares the same flange plane, ports, drive interface and sealing profile.
