Radiator change on zafira 02 plate?

how do i change the radiator on a vauxhall zafira 1.8 petrol engine... do i need to remove the front bumper..if so is this difficult?Radiator change on zafira 02 plate?Yes, and the radiator is simple to remove. Plastic clips along the bottom of the bumper into the subframe (pull out the centres of clip), 4 Philips screws holding each air scoop underneath, Torx screws from wheel arch into bumper (possibly under air scoops too but double check that) and 2 plastic clips along the top of the bumper. Pull bumper outwards from each wheel arch and it will slide off quite easily. Unplug wiring when bumper is off slightly and get someone to hold it to prevent paint damage.Radiator change on zafira 02 plate?Haynes manual (20) Halfords.
