Typical Volvo V40 components

In order to gain

access to the top of the engine, it is first necessary to remove the large plastic cover panel, which incorporates two separate clip-on sections, one of which is shown in this photograph. Work with care; don’t force the plastic or it may fracture!

This V40 is

equipped with a fuel and emissionssaving stop-start system, and the battery MUST be the correct specified type in order to cope, and to work effectively. Adequate electrical power is essential; check all cables and connections too.

The battery’s

negative (earth or ground) terminal incorporates a monitor forming part of the ‘smart charge’ system which is fitted to this Volvo to help save fuel and emissions. Check for condition and signs of corrosion; during servicing clean and lightly grease the terminals.

The alternator

is located on the right-hand side of the engine bay. Its condition and operational effectiveness is key to correct functioning of the ‘smart charge’ (sometimes termed ‘intelligent’) charging set-up. The ECU controls alternator output at all times.
