Common Renault Clio alternator problems you need to know about

Autoelectro shares technical tips on Clios built between 1996 and 2007

Common Renault Clio alternator problems you need to know about

Autoelectro has revealed several bulletins that will help technicians diagnose problems with alternators fitted to Renault Clio models, ranging from 1996 to 2007.

Fluid contamination

Focusing on a 1996-1998 model, the unit can fail because of fluid contamination.

This issue is common on numerous vehicles, not just the Renault in question, and technicians are urged to investigate for a leak, looking out for fluid residue, rust build-up and burning smell, and rectify the problem before fitting replacement unit part number AEA2244.

Tensioning issue

Switching to the 1998-2005 (AEA3297), 2000-2005 (AEA4260) and 1998-2001 (AEA5204) models, the vehicles are fitted with an alternator that can lead to a fault within the drive belt system, which results in a tensioning issue, causing the alternator pulley to split.

The fault can trigger the alternator warning lamp and create excessive noise within the drive belt system.

Autoelectro recommends that the system is examined for any defects and, if there are any signs of belt slip, the alternator pulley or bearings failing, or the alternator has developed a noise, the drive belt should be replaced at the same time as the alternator.

Brackets

Finally, concentrating on the 2005-2007 model, where both AEC1887 and AEK2818 can provide the replacement solution, each unit’s rear brackets are fitted with adjustable sleeves.

If they need adjusting, the bracket must be supported before any pressure is exerted to the bracket or sleeves; otherwise, it is very likely that the bracket will break.

When fitting this type of alternator, technicians must also ensure that each bracket is tightened equally.

If one side is tightened before the other, the alternator will sit at an angle and will exert excessive pressure against the brackets – it is the uneven angle and pressure that will cause the brackets to fail.

Autoelectro has confirmed that this is not a manufacturing defect but a result of incorrect installation.

Autoelectro checks and updates its technical information regularly, and, with its range being updated on a weekly basis, the remanufacturer of starter motors and alternators understands that it needs to continue its mission to arm technicians with the necessary material to avoid problems in the workshop and unnecessary warranty claims.
