While you're under there, mucking about with hoses etc, it might be a good idea to get under the wheel arches, take off the panels that let you look into the engine compartment and check none of the hoses are rubbing and that all the clips designed to stop that happening are in the right place. There are a sh1tload of hoses etc under there and all are prone to wear unless previous mechanics/owners have been meticulous about keeping them apart.
