Hi, I would def get the car serviced for your own piece of mind, take it to a small family VAT reg garage & ask to use fords own Filters Etc, I would when getting the Cam belt changed also get your fan belt done at the same time, when they do the Cam belt the kit comes with a new Tension er Etc, The cost with the service would be within �200--�230. they will also stamp you service book, by doing what I & many would suggest will keep the car in a good serviceable way especially now with Summer coming.
