How we change a timing belt
Steady stream of timing belts from Slough, Hayes and Uxbridge. TDI Golfs, EcoBoost Fiestas, PureTech Peugeots (those need the wet belt though. Different service). If you're unsure which belt your engine has, send the reg over.
Most jobs done in a day. Bigger V-engines and timing chain-and-belt hybrids take longer.
