If you're tired of fighting with your old Webasto it is time to upgrade to a brand new model.  We provide the unit, mounting kit, coolant hose kit, and most important the instructions to make it a pretty easy install.  You need decent wiring skills to accomplish the swap so if you don't have a good relationship with your volt/ohm meter you might want to make friends with someone who does.  Coolant hose kit includes all hoses (cut to length), clamps and vacuum valve.
