Description

The definitive cooling restoration for the Rolls-Royce Silver Seraph (1998–2002). This Genuine PG29063PA thermostat is an electronically controlled 105°C unit housed in a high-grade metal assembly, engineered specifically for the 5.4L V12 engine to maintain precise thermal equilibrium.

Maintain the legendary smoothness of your V12 with this Genuine OEM Thermostat Assembly. This part is the factory-specified fitment for the Rolls-Royce Silver Seraph and early Bentley Arnage V12 models.

Equipped with an integrated electronic sensor and high-grade seals, the PG29063PA ensures your engine operates within the strict 99°C–102°C "settled" temperature range. Unlike generic aftermarket housings, this genuine unit is built to withstand the high-pressure environment of the V12 cooling rail, preventing the common "coolant low" warnings caused by micro-cracks in inferior materials.

Part Number: PG29063PA
Engine Compatibility: 5.4L M73 V12
Opening Temp: 105°C (Electronically Managed)

Tech Tip:

The PG29063PA is an electronically controlled thermostat. When installing, always inspect the electrical connector plug for signs of coolant "wicking"—a common issue where coolant travels up the wire harness into the ECU. Use a new gasket (included) and torque the mounting bolts to exactly 10Nm. Over-tightening can distort the metal housing, leading to a slow weep that is difficult to diagnose once the fan shroud is reinstalled.
