The Toyota Tacoma typically has one drive belt—the serpentine belt—that powers the accessories. There is no timing belt on standard Tacomas because timing is controlled by a chain in the engine.
Across model years, the accessory drive generally uses a single belt for most Tacomas, while the engine timing is handled by a chain. Exact belt arrangements can vary by year and engine variant, so it’s best to check your vehicle’s manual for your specific configuration.
What belt configuration should you expect?
Below is a concise overview of the belt setup you’ll typically find in most Tacomas.
- Accessory drive belt: a single serpentine belt usually powers the alternator, A/C compressor, power steering pump, and water pump (where applicable).
- Timing mechanism: engines use a timing chain, not a belt, to synchronize the camshafts and crankshaft; therefore, there is no separate timing belt to replace during routine maintenance.
In practical terms, you will generally replace one belt during routine maintenance for the accessory drive, while the timing chain remains out of regular belt maintenance unless a separate issue arises.
Model-year notes
Always verify with your owner's manual or a Toyota dealer for your exact year and engine configuration, as rare trims or aftermarket modifications could alter the belt arrangement.
Summary
Most Toyota Tacomas have one belt (the serpentine belt) for accessory power, with engine timing governed by a chain rather than a belt. Always confirm the exact setup for your year and engine in the manual or with a dealer.
