proper install
I found after doing three of these type of jobs it is very easier to completely remove the alternator in order to install the tensioner. Also not shown in the video is to completely clean the sockets that the elbows go into. This can only be done with complete removal of tensioner. A repair video like this must show this procedure otherwise the person doing it will have a comeback due to improper install ( leaks )

Does this part come with the heater hose fittings not the coolant bypass elbows?
