A few days ago I posted this on another existing thread, but decided to remove info and post this on a new thread of its own because maybe others will find it interesting:
Let me say that I am NOT an old sage HD mechanic.......I have a 2016 Tri Glide (water cooled of course) and have been riding only 3 yrs and 32000 miles on this machine.
.......After reading about MANY early water pump failures on 2014-2016 HD water cooled models, I decided to replace my water pump with the newer model pump even though the original one had not failed "YET!!!!!"
........Seems that HD has had such a high failure rate of the original pumps on the 2014-2016 models that they changed the part number and water pump to the new design only. (Best I can tell is this happened the summer of 2018).........Meaning all pumps replaced prior to this time was with the old original pump.........The new pump is radically different from the original and requires the removal of the old thermostat.
........The new pump assembly has no external thermostat and does not require one (I assume something inside the new pump does this function)....This new pump is the same one used on the newer M8's (so says the Dallas HD mechanic)...........The new replacement pump comes in a kit with a redesigned mounting bracket and all new formed hoses, clamps and electric harness adapter.......to install this kit will require the disassembly of both lower fairings as the new hoses must attach to the radiators.
...........I did this job myself so "ANYBODY can do it!" .........The Dallas HD mechanic said it takes him 3.5 hrs for real. (It took me MUCHO longer, but I got it done!)
....Oh yeah: No computer remapping was needed.
.........My extended warranty would have covered the original water pump should it have failed.....BUT, my luck is that it would fail during a long trip somewhere and the local dealer would have to order the part which would mean "Good bye trip plans!"
...........If anyone wants to see the new pump replacement kit and the old parts that will be removed for this job, then please scroll down the page of the following HD forum entry where this dude shows all parts very neatly:
