CADILLAC Northstar starter replacement

I had seen an abundance of questions on "Were is my starter for my Cadillac Northstar engine?" Yes it is very had to see one unless you have a crystal clear engine for it is mounted under the intake inside the engine.
An experience Cadillac tech can have one replaced in less than an hour. I see some do it in 30 minutes and less. (They have replaced hundreds of them through the years made) Changing one is quite simple and a cleaner way of doing it also having it mounted inside. It stays fairly clean through the years.
No gaskets are needed unless you destroy yours somehow
