I agree with the others, $600 isn’t bad for going to a dealership. Just be careful as they may try to “lowball” you with the tempting $600 bill and then try to add on extra stuff you don’t need (i.e. not in your owner’s manual).
Here’s what you can expect:
Timing belt itself replaced
Water Pump replaced
Several seals are usually replaced on the engine. Shouldn’t cost too much extra $ for that and not a bad idea for a 9 year old car.
Engine accessory belts replaced
Belt tensioner pulleys replaced
Engine coolant changed
Oil Changed most likely
Hope that helps.
