Review: Great product, stands the test of time - This review is a bit late as I bought this over 5 years ago, but I guess I can comment on the longevity. I got this because the plastic cracked on my OEM one after 200k miles, and I'm glad I bought this one. I scored this for $120 in 2019 and that was one heck of a deal for this thing. This is a fantastic rad. I do some drifting and the car never even thinks about overheating with this rad like it did with the stock one. The welds are quality and the hose connectors are in the right place. It comes with a Mishi radiator cap, which is cool, and is still working. And this fits fine with the stock overflow bottle. FYI about the overflow, if you end up having a crack in it, don't bother replacing it since it's crazy expensive. Just use some 2 part epoxy and it'll last forever. Note on fitment though: I have a manual transmission and because this rad is thicker than the OEM one, I had to eliminate the surpentine belt dampener that Lexus originally equipped the vehicle with. They put this on manual cars to dampen the shock to the belt and other accessories, I guess so the belt doesn't squeel. But I have had no negative repurcussions leaving this item off the car. Review: Great radiator for the money. - Installed this for my 2001 Lexus IS300. Pretty straight forward install. My only gripe is that the bolt holes didn't quite line up for the fan shroud, and I wish these came with a petcock for draining the radiator, instead of just a bolt. Other than those two things, it's been working wonderfully. I paired this radiator with HPS heater hoses. My car had Mishimoto hoses with a stock radiator, but they weren't in the best shape. The car stays cool, no leaks, and apparently there were reports of the hood hitting the radiator, but I've not had that problem at all. ## Features - Direct fit for the 2001-2005 Lexus IS300 3.0L - Overall Size: 29.1" x 19.9" x 1.92" / Core Size: 14.76" x 27.87" / Rows: 2 - Inlet & Outlet: 1.4" / Core Thickness: 1.42" / Tank Wall Thickness: 0.08" - Drain Plug Thread Size M12 x 1.5 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003GZ8GXY | | Best Sellers Rank | #1,378,457 in Automotive ( See Top 100 in Automotive ) #7,172 in Automotive Replacement Engine Radiators | | Brand | Mishimoto | | Customer Reviews | 4.4 4.4 out of 5 stars (96) | | Date First Available | February 1, 2006 | | Exterior | Machined | | Is Discontinued By Manufacturer | No | | Item Weight | 20.5 pounds | | Item model number | MMRAD-IS300-01 | | Manufacturer | Mishimoto | | Manufacturer Part Number | MMRADIS30001 | | Model | JEGS | | OEM Part Number | MMRAD-IS300-01 | | Product Dimensions | 33.5 x 8 x 24 inches | ## Images ![Mishimoto MMRAD-IS300-01 Performance Aluminum Radiator Fits Lexus IS300 2001-2005 - Image 1](https://m.media-amazon.com/images/I/71Kz1B2GwvL.jpg) ![Mishimoto MMRAD-IS300-01 Performance Aluminum Radiator Fits Lexus IS300 2001-2005 - Image 2](https://m.media-amazon.com/images/I/71AlOuV-YrL.jpg) ![Mishimoto MMRAD-IS300-01 Performance Aluminum Radiator Fits Lexus IS300 2001-2005 - Image 3](https://m.media-amazon.com/images/I/71Ak8zlKhYL.jpg) ![Mishimoto MMRAD-IS300-01 Performance Aluminum Radiator Fits Lexus IS300 2001-2005 - Image 4](https://m.media-amazon.com/images/I/51LVOEJRbGL.jpg) ![Mishimoto MMRAD-IS300-01 Performance Aluminum Radiator Fits Lexus IS300 2001-2005 - Image 5](https://m.media-amazon.com/images/I/51Mok8RVIOL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product, stands the test of time *by S***N on December 6, 2024* This review is a bit late as I bought this over 5 years ago, but I guess I can comment on the longevity.
