  • 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. ... show more

  • Clean and high quality product
Amazing product looks clean AF some modifications necessary like relocation of the coolant temperature sensor from passenger side to driver side and if you own an auto is300 make sure you get the trans cooler with 3/8ths hoses

  • Automatic transmission buyer beware
Easy to install, WARNING IF YOU HAVE A AUTO TRANSMISSION YOU WILL NEED A SEPARATE TRANS COOLER!! Oem radiator has trans oil cooling line that go to bottom, this radiator DOES NOT! I would recommend the Hayden 677 for a small easy and great product to install!

  • Fit perfectly fine
Fit great on my 02 lexus is300 but need a little trimming to fit the oem fan/shrout

  • Great drop in replacement for IS300
Great drop in replacement for my 2002 IS300 manual shift. It's all aluminum so I don't have to worry about the standard plastic housing developing age cracks or seal leaks. I also replaced upper and lower hoses and the thermostat while I had the cooling system apart. Get the OEM Toyota thermostat because it has the jiggle air bubble hole to help bleed the air bubbles instead of a cheaper generic thermostat. ... show more
