i am about to aquire the vauxhall and it has done 35000 miles. when should the timing belt be changed? if it is 40,000 miles should i tell arnold clark to change it free of charge? if it is 60,000 miles i am not bothered i will just change it when it is due. thanks. i used to do cam belts on the old ford pinto engines and was wondering how much difference there is on these modern 16 valve jobs with a veiw to diy. i have never done a 16 valve and find the idea quite daunting without the aid of a haynes manual of which i doubt that i can aquire. How is this for a laugh? the main dealers now recomend 10 years or a 100,000 miles! after swaping and changing over the years. BUT! it is recommended to change at around 50,000 miles!. who is right and who is wrong? it sounds to me that they don't know their arse from their elbow or they have little faith in their engines! There is some good news however. the cost including all the bits is a very resonable £280.
