Replaced a little part today that I wanted to share. Since owning the car for a number of years, coolant has always weeped out of the top of the expansion tank. Even after servicing the entire cooling system. It tends to happen I think when the engine compartment gets really hot (extended idling or stop/go traffic on very hot days). I decided to replace the coolant expansion tank and cap. As usual I ordered from http://www.oemmitsubishiparts.com who seem to have the best prices and quick shipping. The tank was $18 and about another $8 for shipping. The tank comes with the cap. I didn't know, so I bought a separate cap as well. Now I have a spare.
Before and after pics below. We'll see how it works out.
