Frequently asked questions

What does the GA4750 aluminium header tank do?
The GA4750 tank is the expansion and filling point of the engine cooling circuit. It absorbs the change in coolant volume as the engine heats and cools, lets air separate out of the circulating coolant, and carries the pressure cap that sets the cooling system's operating pressure.
Which engines does the GA4750 header tank fit?
The GA4750 aluminium tank fits the Defender and Discovery 1 with the 200Tdi, 300Tdi or V8 engine, and the Range Rover Classic petrol and diesel from 1990 onwards. It replaces the original moulded plastic tank on these engines.
Why fit an aluminium header tank instead of the original plastic one?
Plastic header tanks can crack or become brittle with age and heat cycling, leading to coolant loss. The GA4750 aluminium tank is typically fitted as a more durable replacement for the original plastic tank, in the same mounting position within the cooling circuit.
