Re: XE Repair manual
I have a Max Ellery that covers XD/XE/XF with all motors (3.3, 4.1, EFI, 4.9, 5.8), its not too bad. They cost a bit though (abot $50). I also bought a Gregories off eBay for less than $10, it only covers XE 6cyl (non EFI). It has a bit more XE specific information but isn't as good as the Max Ellery for info (i.e. the Gregories keeps telling you to pull the engine to do anything to the motor, but the Max Ellery tells you how to get around it).
So yeah, buy two and cross-reference them. And if you can't find something then do a search or post something on this site, should get you out of trouble.
