Cambelt and water-pump cost: define the job

Last reviewed · OBDCode UK editorial

We don’t have a verified UK price range for this job yet. A vehicle-specific written estimate is more honest than an unsupported national figure.

What a comparable quote should include

  • The exact engine code and the manufacturer interval being used
  • Which belt, tensioners, idlers, fasteners and seals are in the kit
  • Whether the water pump is driven by or accessed with the belt, and whether coolant is included
  • How timing will be verified after assembly, plus VAT and warranty

How to get two comparable quotes

  • Give both garages the same written brief: registration, symptoms, stored codes and any diagnosis already done
  • Ask each for a written estimate that lists diagnosis, parts, labour, VAT, fluids, extras and warranty as separate lines
  • If the scopes differ, ask the thinner quote to match the fuller one, or treat them as different jobs
  • Compare the evidence and the line items, not the total alone. Do not authorise work from a verbal figure or a code printout

What to ask before authorising work

  • Which exact engine code and manufacturer interval are being used?
  • Which belt, tensioners, idlers, fasteners and seals are included?
  • Is the water pump driven by or accessed with the belt on this engine, and is coolant included?
  • How will timing be verified and what warranty applies?

Safety boundary

Driving is limited when a timing fault is suspected. Timing-belt replacement is specialist engine-timing work requiring workshop lifting and support; no removal, timing or torque procedure is provided.

Where does this guidance come from?

This page is written against the UK MOT record and the official guidance that sits behind it, so you can check the underlying material yourself rather than take this page's word for it. The DVSA publishes anonymised MOT test results as open data under the Open Government Licence, and that release is the source this site is built from.
