hi all

car temp gauge barely lifting off 80% when driving, left sitting idling it will climb until driving again then will drop rapidly, i am assuming this is the symptoms of a stuck open thermostat, now i know they are a right pig to do on the 3.2 v6 vec-c but have someone with the experience to do it but im just wondering what to buy??? just the stat £12 or this http://www.ebay.co.uk/itm/2904461744...84.m1423.l2649

i have heard that the moulding can break when trying to remove so would option 2 be better to buy or has it got to be from vx ???
