How often should a Subaru timing belt be replaced?
The standard replacement interval for most Subaru timing belts is about 105,000 miles (169,000 kilometers). However, exact intervals vary by model and year, and some Subaru engines use timing chains instead of belts. Always consult your owner’s manual or a dealer for your specific vehicle.
Timing belts synchronize the camshaft and crankshaft so the engine's valves open and close in proper time. Because many Subaru engines are interference designs, belt failure can cause valve damage and expensive repairs. Replacing the belt is preventive maintenance, and many shops recommend changing the belt along with the water pump, tensioners, and idlers at the same time to minimize labor and potential leaks.
Official intervals and model variations
Below are typical, commonly cited intervals found in Subaru service materials. Always verify with your specific model/year manual or dealer.
- Most Subaru engines that use a timing belt: replace around 105,000 miles (169,000 kilometers).
- Some older or special editions list 100,000 miles (160,000 kilometers) in their manuals; verify for your exact year and engine family.
- In severe service (frequent short trips, dusty or hot environments, towing, or heavy loads), some owners opt for belt replacement closer to 90,000–100,000 miles as a precaution.
Replacing at or before these intervals helps prevent catastrophic engine damage from a belt failure. Many technicians also replace the water pump, tensioners, and idlers at the same time because labor is similar and worn parts can fail soon after the belt is replaced.
Does your Subaru use a belt or a chain?
Some Subaru engines use timing chains instead of belts, especially in newer generations. Chains generally require less frequent replacement, but chain guides and tensioners still wear and should be inspected at regular service intervals. Always confirm which system your vehicle uses in the owner's manual; if it's a belt, follow the belt interval above.
What to expect during replacement
A timing belt replacement typically includes replacing the belt, tensioners, idlers, and often the water pump and related seals. Labor is a major portion of the cost and can vary by region and shop. Most dealers and independent shops can complete the job within a few hours, depending on vehicle access and whether additional services are needed.
Cost considerations
Costs vary by model year, location, and whether you replace only the belt or also the water pump and other wear-prone components. Typical total ranges in many markets fall around $500–$1,200 USD, with higher-end labor charges or rare models pushing beyond that. Getting multiple quotes and confirming included parts is recommended.
Summary
For most Subarus that still use a timing belt, plan for replacement around 105,000 miles (approximately 169,000 kilometers). Always verify with your manual, as some models and earlier years may differ, and recent Subarus may use a timing chain instead of a belt. Replacing the belt on schedule—and often with the water pump and tensioners—protects the engine from severe damage and saves money in the long run.
How often should I replace my Subaru timing belt?
105,000 miles
Timing belt replacements:
Subaru timing belts need to be replaced after seven years or 105,000 miles; whichever comes first. Replacement cost starts at $530 (will vary by model)
Do subarus have timing belt issues?
Just like rubber accessory belts under the hood, the timing belt may stretch and crack over time. And since modern Subaru engines are interference engines, that means that a broken timing belt could cause severe damage to the engine! That's why it's crucial to get the timing belt on your Subaru changed before it fails.
How do I know if my Subaru needs a new timing belt?
A failing timing belt may show a myriad of symptoms, such as noises coming from the front of the vehicle, engine misfires, and decreased engine performance. In many situations, if the timing belt breaks, the engine will no longer run, and the engine will not restart without replacing the timing belt.
What year to stay away from a Subaru Outback?
Years to avoid for the Subaru Outback include 2010–2014, which had widespread CVT, oil consumption, and oil leak issues, and 2018, which had recalls and reliability concerns. Additionally, some sources recommend avoiding the 2005–2007 models due to head gasket problems and the 2020 model, which had electrical and windshield issues.
Years to avoid
- 2010–2014: These models are frequently cited for significant transmission issues (CVT), oil consumption, and general reliability problems. The 2010 model specifically had issues with the torque converter locking up.
- 2018: This year saw recalls and owner complaints related to oil consumption, exhaust components, and electrical issues.
- 2005–2007: These models are known for head gasket failures, which can cause coolant and oil leaks.
- 2020: This model year is associated with a high number of electrical problems, including dead batteries and stalling, as well as issues with the windshield cracking from small chips.
Other potential problem years
- 2013: Frequently mentioned for oil consumption issues.
- 2015: Some reports list it with electrical and engine problems.
- 2017: Reliability issues were noted.
