I would wiat till you had the symtoms before replacing parts, especially the t-stat, that's about an 8 hour job.What about CPS and the thermostat. Wait until they go bad or replace now? Also, what about diff. fluid?
I disagree on the CPS. These things can leave you stranded with a car that won't start and you don't always get any symptoms beforehand. We've had a lot of '03 owners report them failing around 80-100k. I wouldn't take a chance - I'd change it, especially since it is relatively inexpensive repair.I would wiat till you had the symtoms before replacing parts, especially the t-stat, that's about an 8 hour job.
