Lexus RX330 radiator replacement - need advice

My radiator is starting to show signs of leaking - and I’ve been advised to replace it. How important is it to buy the radiator from the dealership versus buying an aftermarket radiator? The dealership is quoting me aprox $500 for the radiator - but I do believe I can get a replacement radiator for half that much if I get it elsewhere. Thoughts? Recomendations? Thanks so much for your help!

I would buy a after market. Check www.rockauto.com They seem to have pretty good prices.

If you want to buy local, call up one of those small mom-and-pop radiator shops in your area.

I’ve done that a few times and their prices were often lower than the online prices.
