Does a 2013 Subaru BRZ have a timing belt or chain?
The 2013 Subaru BRZ uses a timing chain, not a timing belt.
In detail, the BRZ is powered by a 2.0-liter FA20 flat-four engine with dual overhead cams and variable valve timing. Subaru chose a chain-driven timing system for this engine, a common setup in modern Subaru designs and related Toyota co-developed powerplants. The timing chain is designed for long life when the engine is properly maintained, unlike timing belts which require periodic replacement.
Understanding the BRZ's timing system
Key details about how the BRZ's timing system works and what you should know:
- The engine uses a steel timing chain rather than a rubber timing belt.
- The chain links the crankshaft to the camshafts, with hydraulic tensioners to maintain proper tension and synchronization.
- It is an interference engine, so timing issues can cause valve–piston contact if the chain or tensioners fail.
- With regular oil changes and proper maintenance, the chain is designed for long life, though wear can occur with high mileage or neglect.
In practice, BRZ owners typically do not replace a timing chain as part of routine maintenance; technicians monitor chain slack and tensioner operation, and address any unusual noises or timing concerns as they arise.
Maintenance considerations
Keeping the timing chain healthy depends on routine maintenance and attentive listening for signs of wear. Here are practical steps for BRZ owners and prospective buyers:
- Follow Subaru's recommended oil change schedule and use the correct viscosity; clean oil helps maintain chain tensioners and chain lubrication.
- Be alert for unusual engine noises at startup or idle, such as rattling or clattering, which could indicate tensioner wear or chain wear.
- Have a dealer or qualified shop inspect the chain and tensioners if you notice rough running, misfires, or codes related to cam timing or VVT.
- When buying a used BRZ, review maintenance history for oil changes and any service related to the timing chain or tensioners.
Regular maintenance reduces the risk of chain-related issues, and early detection can prevent costly damage.
Summary
Bottom line: The 2013 Subaru BRZ relies on a timing chain, not a belt, to synchronize the engine’s camshafts. This chain is designed for long life with proper oil maintenance, and there is no routine timing-belt replacement interval. If you notice unusual noises or timing-related symptoms, consult a qualified technician for a check of the chain and tensioners.
