98 V70 T5 Replacing the Coolant Hoses in Pics

You’ll want to remove your air cleaner box and also the duct pointing to the front part of the car. The air cleaner is set in with some tabs into a rubber retainer. Just pull up and to the passenger side to get it out. There were a few connections that need to be removed as well. Finally, tie the accordion air duct out of the way so that you’ll have a clear view. They are already out in this picture. I just highlighted where these parts used to be. It really opens up the area.

Standing on the driver side, you can look are clearly see the large hose (lower radiator hose) where it connects to the neck into the engine block. You can also see where the heater hoses go into the firewall. The Lower radiator hose is not too hard to access at this point. Loosen the clamp (above the yellow arrow in the picture) and pull it off. The other end is on the bottom of the radiator on the driver side. You’ll have to remove the lower engine cover plastic to get access to that.
