Just got a killer deal on a 2009 LX, already has leaks and the hairline crack but I used it as more negotiating ammo....dealer was clueless.No Lexus dealer in my city, but the Toyota dealer is trying to charge me $458 for the radiator and est. $700 ($140/hr) in labor. Debating on ordering a OEM for $300 or a DENSO ($250ish) one and having it installed by a trusted indy for $470 (94/hr) ish. Pretty much read through this entire post...any final verdict on the OEM (16400-50384) vs an aftermarket like a DENSO?
$700 in labor seems high. The book rate on my 2013 is 2.1 hours for the radiator, 0.1 hours for each of the hoses, and 0.8 hours for the water pump. Radiator + labor @ $700 wouldn't be unreasonable.
IMO the radiator and labor should about $600. Another $250-300 to also do the water pump. I don't know the mileage on your 2009 but if they are in there I'd do both since the water pump is known to fail in the 100-150k range, along with the hoses (which are cheap).
