I sprung for the BlueDriver setup. Will definitely be monitoring it for the next few days as the wife is pretty razzled about having it die on her... TWICE.

The oil thermostat housing gasket is for cars with an oil cooler. Look inside the lower driver side grill and if you have one of those it's pretty easy to change. If you don't have an oil cooler then you have an alternator bracket gasket and that thing is a nightmare to change.

Thanks again for your help!
