Yes, there are a few ways you can do it. - How much effort do you want to go to?
Changing the hoses is a piece of piss if the engine is out, but getting it out is a pain in the arse.
Taking the inlet manifold off will give you a lot of room to see what you're doing... but then you need to take the inlet manifold off.
You can reach the hose from underneath (or round the sides), but you'll be on your back for a while trying to get the old ones out and the new ones in. - This time of year it can be a bit cold and wet for that kind of thing (and I'm not talking about the water which will be dripping on you from the engine either).
So if you've got an engine hoist, just take the engine out. If you've got access to ramps or a pit, you might be able to do it from underneath with no real problems... but if it's sitting in your drive with all the original brackets on; consider taking the inlet manifold out.
