2003 Hyundai Lantra 2.0 diesel bought from main dealeer from new and serviced there to date. In Nov 09 at 65000 miles the cambelt was changed. This week the car had to be returned to the main dealer as the engine was sounding like a tractor. Diagnosed cam belt tensioner bearing failure and charged £400+ to repair with majority being labour. Apparently it would have cost £30 extra to change when the cambelt was done. Dealer says tensioner was checked at belt change but is not changed as matter of course. Is this just one of those things or should tensioner have been changed with cambelt?
The tensionr should not have been changed as a matter of course though they could have called and advised to do it. It is not the responsibility of the garage to make decisions based on other parts when changing a cam belt. If they did they'd be accused of trying to replace parts that did not need it.
I will yes it is highly recommended by most if not all motor manufacfures to change T belt with all tensioners ,idle pulleys and water pump if T belt driven.Request to read the workshop manual and or service book T belt schedule change guide.
no real hard & fast rule, but many people in the know would change it at the same time as a precaution, but you could say the same thing about the waterpump, where do you stop?...all down to finance
the other side of this is, if the garage had recomended it they may then be accused of upselling carrying out uneccessary work etc...bit of a no win situation on there part.
