PCU103790 - Land Rover Bracket-radiator mounting

Land Rover Defender Left‑Hand Radiator Mounting Bracket – PCU103790 (Td5 & Puma, 1998–2016)

PCU103790 is the left‑hand radiator mounting bracket fitted to Land Rover Defender 90, 110 and 130 models equipped with the Td5 and Puma diesel engines, covering production from 1998 through to the end of L316 manufacturing in 2016. The bracket secures the radiator assembly to the front panel and chassis structure, forming a key part of the cooling‑system support frame on all post‑1998 Defenders.

Manufactured in pressed and formed steel on genuine Land Rover versions, PCU103790 incorporates the precise bolt‑pattern, mounting-hole geometry and central location aperture required to seat the radiator correctly, preventing unwanted movement and maintaining alignment with the intercooler, fan cowling and ducting. The bracket’s shape matches the left‑hand side of the Defender’s front-end structure, including the rolled profile and reinforcement stamping introduced for the Td5 platform.

Used in conjunction with the corresponding right‑hand bracket (PCU103780), PCU103790 stabilises the radiator under load, distributing weight across the front panel and helping to reduce stress on hoses, coolant fittings and the intercooler mounts. On vehicles used heavily off‑road, this bracket also contributes to vibration control, mitigating fatigue on the radiator core and plastic side tanks.

PCU103790 supersedes earlier Defender radiator‑mount designs dating from the 300Tdi era and is engineered specifically for the chassis, cooling‑package architecture and fan‑shroud layout adopted from the 1999 Td5 redesign onwards. A worn or corroded bracket can allow the radiator to shift under vibration, producing coolant leaks, premature hose wear, or misalignment between the cowling and fan, issues particularly common on high‑mileage Defenders. Genuine‑spec components maintain the original rigidity and mounting precision required for proper cooling system performance.
