My apologies. I have a 01 GTi AUM 150bhp k03s 96,000 miles, 3 door. The car has been serviced every couple of years as it did only 2000 miles a year for the last 4 or 5 years. It has had 2 belt changes but the last was at 60k(more than 5 years ago). I saw cracking on both belts so figured to change both at the same time. I also need to change the Thermostat as I had a fault code which pointed to that and/or the sendor(replaced this one myself). I have read that it is good to change the water pump when doing the belt. I would assume that changing all the other items would be a good idea due to the age of the car, but is it necessary? Any idea how long it would take to replace all the items by a mechanic? I have a mate who has mechanic friends who can do it in their spare time, but I just wanted to see how long it would take so I can judge a rough cost.
