I’m an auto mechanic by trade and have done a lot of these.

Do not cut off the aluminum tubes. The tees are for the rear heater and are plastic,I would replace them and get from GM.

The fittings to the engine hoses would work with the ones you have on Amazon. I would recommend new GM hose assemblies though.

Buy some hose fitting release tools from Amazon. Push the fitting tight and install the tool from the rear to remove. Practice on the new ones.

Again, do not cut off the aluminum lines or you will have no way to replace the tees.
