I know just a another stupid t-stat,,,,but this is special,,,,it’s for the new service action on a new G12 750,,,,there are 4 new service actions at the same time.
Here are the new exhaust turbo coolant hoses that will be replaced.
Here are both the turbo wastegate that will be replaced,,,,,and programming the vehicle with a new software update for the new waste gates,,,,,,and the 4 th thing is a updated oil service depending on mileage.
Here the t-stat which we gain access from underneath the car.
Here you can see the new turbo coolant hoses are replaced with numbers on them so you can tell which hose is leaking,,,,next to them is one of the turbo waste gates.
Here the over head shot of the new G12 engine lay out,,,,a better look at the turbo coolant hoses and oth turbo waste gates.
Here’s good news for some of you guys,,,,BMW changed the bad design on some of the hoses,,,,the installed metal clips you lift up,,,,you can see it on the vent valve and the turbo charge pipe,,,,so no more plastic clips that always break.

Unfortunately the coolant hoses for the old N63B44 engine were not overhauled. That means if the hose is faulty the turbos must be unmounted to install the new hoses because it comes with the metall pipe on it. 😦 Same thing with the crankcase ventilation pipes….

The metal pipes that go downward from the turbos are the oil return pipes for the turbos,,,,,they can be remove and replaced from the turbos.

Snap-on tool part number TM615 flexible driver with a 1/4″ drive,,,,then you use a 6mm socket,,,,,,you will still have to remove both turbo charge pipes from the air filters and both rubber charge hoses to the turbos

Thank you very much, Sir! It is the same which you have mentioned to change the N63 Y-Coolant line in the hot V. I have ordered the german tool: https://www.amazon.de/gp/product/B001ILAGJU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
