So far, working great on 2010 lexus is350 C. Made in Indonesia now, not Japan like the stock one. Fits well.

Great replacement radiator 09 IS250
I needed a good Replacement radiator and I found this one. I took it to a local shop and have them install it and it’s been working great since installing it. It fit perfect in my 2009 Lexus IS250.

Bad Business
Why did you pick this product vs others?: I give this Supplier, (Autoplicity) ZERO "0" STARS - Purchased this radiator in January 2025, Starting having coolant leaking problems in June 2025 thinking maybe it's a hose that needs replacing and no way did I think it was the new radiator I purchased just 6 months ago. Had my mechanic take a look at it and said the 6 month old radiator is leaking at the top seam and lower right corner. I thought DENSO was a reputable company, so I 'm thinking maybe a faulty item, I can reach out to the supplier and have them send me a replacement being the radiator was only 6 months old. Reached out to Amazon and was forwarded to Autoplicity (supplier). Autoplicity passed the buck to DENSO stating they did not manufacture the item, nor do they stand by any warranties of product they sell. Well DENSO does not sell to Amazon only to NAPPA, Advance Auto, Auto Zone...long story short buy from a reputable supplier and triple check warranties. Quality: DENSO is a well known car part manufacturer

Nice radiator
Great replacement for my 2011 Lexus IS 250. Local auto stores wanted double the price for the same Denso Radiator.
