Cost of replacing timing belt on GS 300 ?

Chris,

$650 sounds pretty reasonable to me. Yes, a Toyota dealer should be able to handle it, but a Lexus dealer probably sees ten IS300s and GS300s for every Supra that the Toyota dealer sees, so I'd recommend you have Lexus do it. I doubt a Toyota dealer would be significantly cheaper although you could call around.

You might want to double check the factory manual, because it's possible that the timing belt is a chain and doesn't require replacement in that engine.

Also, be careful on this one-- the timing belt might be $650, but every time I've had one changed (an 82 Celica, 89 Accord, 96 RAV4) the dealer also recommends replacing the water pump and all the reqular fan belts, since they have to be removed to get to the timing belt anyway. When all is said and done, the timing belt accounts for maybe half the cost. So this repair will really end up costing you $1000-$1300.

That sounds very expensive considering that I just had the belt changed on my Sienna at the dealer for $175, including parts. If anything the belt on the GS/IS 3.0L6 looks more accessible than the belt on the Sienna's transverse V6. The GS300's engine has a water pump that is driven by a standard v-belt rather than the timing belt and the pump can be changed without disturbing the timing belt - don't let them sell you that crock!
