Silicone Coolant Hose Kit - a five-piece silicone hose set that replaces the main radiator and coolant-system hoses on the 2.4L TDCi (Puma) diesel cooling circuit.

Silicone construction tolerates higher operating temperatures than the original rubber hoses and resists the hardening, splitting and perishing that affect rubber with age.

Note: some coolant types are not compatible with silicone hoses - check coolant compatibility before fitting.

Frequently asked questions

What is the GA4575 silicone coolant hose kit and what does it replace?
The GA4575 is a five-piece silicone hose set that replaces the main radiator and coolant-system hoses on the Land Rover Defender (2007 to 2016) 2.4 litre diesel cooling circuit. Silicone tolerates higher operating temperatures than the original rubber hoses.
Does the kit cover the whole main coolant circuit?
The kit covers the main radiator and coolant-system hoses as a five-piece set, so it replaces the principal hoses in one go. It's a direct replacement for the aged rubber hoses on the Defender 2.4 diesel cooling system.
Is silicone hose compatible with any coolant?
No. Some coolant types aren't compatible with silicone hoses, so check coolant compatibility before fitting. Silicone resists the hardening, splitting and perishing that affect rubber hoses with age on the Defender cooling circuit.
Why do the original coolant hoses fail on these Defenders?
The original rubber coolant hoses typically harden, split and perish with age and heat cycling, which can cause coolant leaks and overheating. Silicone construction resists this and lasts longer on the Defender 2.4 diesel cooling system.
