Hi, Greenmtrider,
Reading what the dealership did, I would also recommend changing brake fluid and engine coolant if you don't know they've both been changed within a year. Brake fluid should be changed on a yearly basis. If you use a long-life coolant (all I can seem to find at WalMart these days), you can let it go for a couple or three years. But every once-in-a-while, move the fuel tank back and open the coolant filler cap and check the coolant level. If a bit low, bring it up to the top, then suspect the hose from the fill connection to the overflow bottle is old and leaking, flowing hot coolant out when the engine is hot, but allowing air to enter when coolant should be flowing back into the system from the overflow bottle.
