Prepping a 2011 legacy 3.6 with 180k for winter

[Miklman3477]

So I just bought a 3.6 legacy with 180k and I am prepping it for a winter that will be full of plenty of trips up to the mountains and at least a few winter road trips 1500+ miles. I have already flushed all the fluids and next I’m planning on doing the plugs & boots, SERP belt, battery, and all coolant hoses including heater hoses, throttle body hoses etc. I will also be doing the thermostat, rad cap, and PCV valve. I’m wondering if there are any known issues with high mileage 3.6 that I should look out for? The suspension is solid and I just threw some winter tires on it
