While looking for a tubo boost leak I noticed that the turbo coolant hose on the top is starting to crack. Luckily it did not start blowing coolant everywhere going down the road. My question is whether I can change this hose without draining a bunch of coolant out of the radiator. It is bound to leak some when it comes off but I just wanted to know if it would spew out a bunch if I did drain the radiator. Anyone do this before?
