FAQs About 2016 Outback Thermostats

❓ How often should the thermostat be replaced? Generally around 100,000 miles, or if symptoms of failure appear earlier.

❓ Can I replace it myself? Yes—if you're comfortable handling coolant and basic tools, it's a moderate DIY project.

❓ What coolant should I use after replacement? Use Subaru Super Coolant or a high-quality phosphate-free, silicate-free coolant recommended for Subarus.

❓ What happens if the thermostat fails closed? Coolant won’t circulate, leading to rapid overheating and potential engine damage.

❓ What happens if it fails open? The engine may run too cool, resulting in poor fuel economy and weak cabin heat.
