Started out with an oil change in the driveway on our 2007 this afternoon and ended up replacing the oil block-off plate gasket and the radiator as both were leaking. 2.5 hours for everything, including a trip to the parts store and a couple of beers. She (her name is Delilah) had been in the garage resting while my wife and I were traveling, and when I took her to the liquor store over lunch today I could smell that sweet coolant smell when I got home in the driveway. Coolant reservoir was just a hair low and I traced the leak to what I thought was a crack on the driver's side end tank near where the power steering cooler line passes by it, down low. Got the radiator out and the real leak was where the end tank and core meet. The gasket had started weeping pretty good, so I'm glad I got it out before our trip to Snowshoe coming up this weekend.
Ended up buying the replacement locally. It's a Carquest Premium because I didn't have time to wait for one to be shipped in. The core was the same 34" wide but is only 1" thick vs about 1.25" for the original. So I checked all of the units on Rock Auto and they're all the same 1" thick core. Presumably it will be okay, but my wife and I have a trip to Colorado planned in June pulling a cargo trailer, so fingers crossed.
