Getting ready to do a timing belt/water pump change on a '99 Camry V6 due to age. Last belt was done in 2010. What is your opinion as to whether to replace tensioner? I'm getting conflicting info. This car belongs to someone else and they are instructing me to do whatever I think is best. My understanding is it is not normally replaced with the timing belt. It only cost $62 OEM from Dealer.
