Timing Belts (Cambelts) – Welwyn Garden City

A timing belt keeps your engine’s valves and pistons moving in sync, and it’s one of the few parts on your car where failure doesn’t just mean a repair, it often means a completely new engine. At Collect Service Go, we replace timing belts on schedule, before they become a problem rather than after.

Why timing belt replacement is different from other jobs

Most parts on a car give some warning before they fail completely. A timing belt often doesn’t. On many engines, known as interference engines, a snapped timing belt allows the pistons and valves to collide, causing damage that can write off the engine entirely. Replacing the belt on schedule is far cheaper than the alternative.

Signs your timing belt may be wearing

Because failure can happen suddenly, we don’t rely on symptoms alone to judge when a belt needs replacing. That said, it’s worth having your car checked if you notice:

• A ticking noise coming from the engine
• Visible cracking or fraying if the belt is checked
• Engine misfires or difficulty starting
• Oil leaking near the timing cover

When should a timing belt be replaced?

Replacement intervals vary by manufacturer, but most fall somewhere between 60,000 and 100,000 miles, or a set number of years, whichever comes first. We’ll always follow your manufacturer’s specific schedule rather than a generic figure, since intervals differ significantly between engines.

What’s included in the job

Timing belt replacement usually includes the belt itself, along with the tensioner and idler pulleys, since these wear at a similar rate and replacing them together avoids paying for the same labour twice. On many engines, we’ll also check the water pump while access allows, as it’s often driven by the same belt.

Why book your timing belt replacement with us

We work to the interval your manufacturer sets, not a rounded-up figure designed to bring you back sooner than necessary, and we replace the full kit rather than the belt alone. Every job comes with a 12 month guarantee on parts and labour.
