About this product
Sourced from HART, this cooling module (627 731) combines precision engineering with durable materials to meet the demands of everyday driving and extended service intervals. Technical specifications — Core Length [mm]: 510 mm, Core Width [mm]: 388 mm, Core Depth [mm]: Silicone mm — are verified against the OEM data sheet to guarantee fitment accuracy and performance parity with the original equipment. Verified to fit NISSAN models. All compatibility data is cross-checked against the TecDoc database — select your vehicle to confirm the part matches your specific engine and year. This part supersedes original equipment references: 21400-AX600, 21400-AX601, 21400BC00A, 21400-BC00B and 3 more. Matching these numbers confirms a like-for-like replacement with no loss of function. HART is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched with tracked delivery and a 14-day money-back guarantee with hassle-free returns.
