It’s the 4.4 v8

The hoses are easy enough to change. Slide all 4 further onto the donut to be clear of the manifold connection, remove the donut, swap the hoses then refit the donut. I used silicone spray on the donut to make the new silicone hoses slide more easily.
You might want to allow quite some time to cleanout the donut while its off.

Thanks will give it a go 😊

Just another one for you, had is plugged into scanner today while driving and ran a data stream

CATTEMP21 was in the 400s and fluctuating more
