Greetings,

I have a 2009 Expedition with 170k.

1. The A/C is leaking. I bought the truck about a week ago and the A/C blew cold, but not anymore. What are common areas for leakage?

2. I got P0112 and P0122 CEL codes and want to do a timing refresh; should I buy a kit that includes the actual cam phasers for $850, or can I get away with just buy the chains, guides, and tensioners?

3. I have two sets of wheels, 17" and 18". What are the largest winter tires I can run on the factory 17" wheels? They currently have 265/70.

Thanks so much for any and all help!

The 2 codes you've got have nothing to do with cam phasers or chains. Why are you digging into the chains/ tenshioners? 1 code is for intake air sensor, the other is throttle position sensor.
