Frequently asked questions

What is the ETC4153 and what does it do?
The ETC4153 is the auxiliary drive belt idler pulley and arm for early Land Rover Defender engines. The arm positions the idler pulley to route and tension the ancillary belt around the engine accessories, keeping consistent belt wrap. Genuine Land Rover part.
Which engines does the ETC4153 fit?
The ETC4153 fits Land Rover Defender engines up to 2006 fitted with the Adwest power steering pump. The pump type matters here, so confirm your engine runs an Adwest pump before ordering, as belt routing differs between setups.
How do I know the idler pulley needs replacing?
An auxiliary belt idler pulley typically needs replacing when the bearing becomes noisy, rough, or develops play. A worn idler can cause belt squeal or misalignment. Spin the pulley by hand with the belt off to check for roughness or wobble.
