Mounts should/will be different because the geometry of the bumper changed with the "aero dynamic" front end.
I think the bumper would kinda look funny to me because of the rounded front on the obs compared to the brick nose, but it's all up to your taste on what it looks like.
Might try changing the filter and bleeding the system. Depending on how bad it was the filter could have crap in it now and air in the lines.
Power service 911 would take care of the gelling if it's jelled now, just follow the directions on it.
I run Power service winter (silver bottle if I remember correctly, haven't bought any in a while) during the winter, October-March around here.. And Power Service white bottle in the summer (lube and cetane additive). About 4-6 oz in front and 2-3 oz in the rear. (.32 oz/gallon or so I like to run it a little hot). I never try to run the tanks dry so it never exact.
