I have a very nice wife I married two years ago, She has a 2008 4 cylinder RAV4 limited. We have been pushing the Rav4 limits towing a 18ft ski boat with it. Well I now am replacing it with a 4.8l 2007 x5 ... she loves the power and sitting high and the posh. But we both know it isn't the RAV4 for reliability. Well the x5 at 105000 hadn't had it's transmission filter-fluid changed and it was leaking badly from the pan gasket ... that was a needed and easy fix. Harder fix will be the oil cooler gasket smaller drip, that according to what I read requires many hours of "undoing" to get to it? I will be researching that carefully, and I need to get my camera probe in there and inspect carefully too. Perhaps I can work out a custom socket setup and not undo so much? FYI also had the AC fan just stop ... turned out the bearings for the fan where bound up .... it wasn't hard to pull it and lubricate it ... if it fails again I replace it. Hopefully I get the X5 reliable and then I just maintain it like a aircraft. If my wife loves it and I am getting DIY credits with HER why not! :-)
