Engine timing chain tensioners for your Plymouth Voyager start at $7.95, with 1 units in stock from Cloyes. The tensioner keeps constant hydraulic or mechanical pressure on the timing chain, preventing slack. When it fails, chain slap and skipped timing can cause misfires, rattling on startup, and in severe cases, catastrophic engine damage.
The key decisions are OE-style hydraulic versus ratcheting mechanical design, and whether your Plymouth Voyager uses a single tensioner or separate primary and secondary units. Matching the tensioner type exactly to your engine's design is critical — substituting a mechanical unit for a hydraulic one, or vice versa, will cause immediate failure. Always confirm whether your engine requires one tensioner or a full set before ordering.
| Option | Best for | What you get |
|---|---|---|
| OE-Replacement Hydraulic Tensioner | Most daily drivers; engines originally equipped with oil-fed tensioners | Direct-fit unit that uses engine oil pressure to maintain chain tension automatically; matches factory operation |
| Ratcheting Mechanical Tensioner | High-mileage engines or performance builds where oil pressure delivery is a concern | Spring-loaded ratchet mechanism that holds tension without relying on oil pressure; more consistent cold-start performance |
| Primary Chain Tensioner | Engines with a two-stage chain system requiring the main crankshaft-to-intermediate shaft tensioner | Controls the larger, higher-load primary chain loop; typically the first to show wear symptoms |
| Secondary Chain Tensioner | Engines with dual overhead cams requiring separate tensioners per cam chain | Smaller tensioner controlling cam-to-cam or intermediate-to-cam chains; often sold individually or as a kit with guides |
Begin by draining the oil and removing any covers, brackets, or accessories blocking access to the timing chain area, which may include the valve cover, front engine cover, or both depending on your Plymouth Voyager's engine layout. Before removing the old tensioner, lock the camshaft and crankshaft in their correct timing positions using the appropriate locking tools to prevent the chain from skipping during the swap. Install the new tensioner according to the manufacturer's priming instructions — hydraulic units often require pre-filling or a specific release procedure — then torque all fasteners to specification and verify timing marks are correctly aligned before reassembly.
