Frequently asked questions

What does the ERR6658 ancillary drive idler pulley do on a Td5?

The ERR6658 is the idler pulley for the ancillary drive belt on the 2.5L Td5 five-cylinder diesel. It maintains belt tension and alignment on the serpentine system driving the alternator and ancillaries. It fits the Defender (up to 2006) and Discovery 2 (1998-2004) Td5.

What are the signs the idler pulley is failing on a Td5?

A worn idler pulley typically produces a squealing or rumbling noise from the front of the engine, varying with engine speed. On the Td5, a seized or wobbling pulley can cause rapid belt wear or belt failure, leaving the alternator and ancillaries without drive.

Does this fit Discovery 2 Td5 models with ACE?

No. ERR6658 fits Discovery 2 Td5 models without ACE (Active Cornering Enhancement). The ACE system uses an additional hydraulic pump driven by the ancillary belt, which requires a different pulley configuration. Check your vehicle specification before ordering.
