Engine timing chains for your Chevrolet Townsman start at $12.95, with 25 options in stock from Cloyes. The timing chain synchronizes the crankshaft and camshaft so valves open and close at the correct moment. When it stretches, skips, or snaps, the engine loses power, runs roughly, or suffers catastrophic internal damage.
Timing chains are not one-size-fits-all — kits vary by whether they include just the chain or the full set of guides, tensioners, and sprockets needed for a reliable repair. Buying a complete kit costs more upfront but avoids having worn secondary components undo a new chain within months.
| Option | Best for | What you get |
|---|---|---|
| Chain only (single link chain) | Confirmed chain stretch with verified good guides and tensioner | Replacement drive chain; must reuse existing hardware |
| Timing chain kit (chain + guides + tensioner) | Full refresh at normal service or first-time replacement | Everything needed for a complete, reliable repair in one box |
| Timing chain kit with VVT components | Vehicles with variable valve timing where sprockets or actuators are also worn | Chain, guides, tensioner, and VVT-specific gears or solenoids |
| OE-equivalent (OEM-spec chain pitch and link count) | Owners who want factory fit and longevity without dealer pricing | Chains manufactured to original specification using matched steel alloy |
Replacing a timing chain requires draining engine fluids, removing the front engine cover, and precisely locking the camshaft and crankshaft at top dead center before touching any components. All timing marks must be aligned exactly before the new chain and sprockets are installed, since even one tooth off will cause misfires or engine damage. This job is recommended for experienced DIYers with the correct engine-specific alignment tools; incorrect assembly can destroy the engine on the first start.
