what exactly gets done with the 90,000 mile service? what is everything that they change and do?

check out the site below tells it all!

90k service varies on the dealership you take it to. most of them will do a change of tranmission fluid, oil change, engine air filter replacement, rotation and balance, valve adjustment, lubricate chassis,change your wipers, inspect and adjust brakes, look over the entire vehicle, belts, hoses, check your battery, cooling system ect. seperatley from the service they will recommend your timing belt/ water pump/ engine belts replacement ( because of the miles) as well as an induction service(fuel system clean up), brake fluid change, four wheel alignment, and a/c filter... your looking at about $1700.00 worth of work if you have all of it done ( now that price is just an estimate) good luck!

all the info is in your manual.
