Timing Belt vs Timing Chain: What Pakistani Car Owners Must Know

What Does the Timing Belt Do?

The timing belt synchronizes your engine's crankshaft and camshafts. If it snaps, pistons and valves crash into each other — causing catastrophic, irreparable engine damage. This can cost Rs 200,000–600,000 to repair.

Does Your Pakistani Car Have a Belt or Chain?

• Mitsubishi Lancer 1.5: Every 60,000 km

• Repair cost: Rs 150,000–400,000
• Many engines are write-offs after timing belt failure
