Paging
@ToyotaMatt to the parts courtesy phone.
You can buy brand new Weber 32/36 DGV carbs for $300 - $400 and likely good used ones for less.
Its common for these exhaust manifolds to warp over time....and to machine them properly the intake and exhaust have to be machined together....
but $700 sounds very high for this work. Edit.... didn't realize this was just reflecting the labor to remove and install at the shop.
So I just spoke to a machine shop a couple days ago. They’d charge me $100 to resurface the exhaust and intake manifold. Does that sound about right? Appreciate your insight!
Lastly that cooler hose...its nothing fancy and while there still may be a toyota part available its just a rubber coolant hose with a couple of clamps. If you use a new piece of hose and new clamps you are looking at maybe $15 in parts. If the truck is cold and you work quickly you can probably even swap the hose out without losing to much coolant. If I go conservative here we might say 30 minutes of labor and $20 in parts if they have to add some coolant. So maybe $50 - $60 line item.
