  • Easy DIY guide: Renew the main upper engine mounts for a Ford Duratec. Featured is a Mondeo Mk3; the parts and process are similar for all Duratec installs such as in a Focus, same for Mazda MZRs, and indeed most engine mounts in any car.
    The RH (engine) side mount on the Duratec featured is a hydraulic dampening mount, which fail when the rubber perishes and cracks or is damaged allowing the fluid the drain out. In this case my vibration problem was a product of this mount failing (lifetime approx. 12 years and 120,000 km).

    Required:
    10 mm socket with 1/4" or 3/8" ratchet handle (coolant expansion tank)
    1/2" breaker bar, decent length extension bar, and deep socket sizes 15 mm, 18 mm, and 21 mm
    1/2" Torque wrench (ideally). Nb. I torque the bolts by estimating force applied to a known breaker bar length.
    New engine mounts to suit engine and fitting. You would ideally replace in pairs even though only one typically fails at a time.
    Nb. the examples featured may be of identical design geometry for your case, but can vary (particularly the LH side) in rubber compound for engine weight/power. Ford use a color label to identify rubber compounds (you can see the LH mount is marked brown), while the alloy castings of the mount bodies themselves do not differ - so take care to ensure your replacement mount matches the old one.
    Flat bladed screwdriver to remove air intake hose clamp, and long nose pliers to redo.
