My '98 V70 had steam pouring from the engine compartment. I opened the hood to find a small hose had split and was leaking coolant. Quite a bit. The hose is about 3 inches long and located on the passenger side, just rear of the cylinder head, and just beneath something that looks like a coil or spring sting out from the cylinder head. Any idea what this hose is called? I can easily replace it, probably, if I can get to the dealership with the right information. Also, what coolant should I refill the system with if I am not sure what was in there in the first place. I think it was just prestone or something.

Thanks!
