I'm curious how much it should cost to change the timing belt on a 2002 /V6. Truck has 90k on it so its ready. The dealer said around a grand including water pump and seals. A little shop by my house says about $500 for the same thing but not using genuine toyota parts. Whats the going rate ? Any reccomendations on a shop in so cal I can trust to do it right. Also reading about kevlar belts is it worth the extra.
