Hi everyone, I recently found a leak in the top plastic part of the radiator.
Can anyone suggest me a good replacement radiator for our cars. After reading some reviews I have a good feeling about Koyorad all aluminum radiators.

Any suggestions ?....thank you

Have you checked an OEM replacement? How much was it?

The radiator is $549 +tax at the local Lexus.

I'd replace the entire thing personally and the hoses and clamps associated with it for good measure...give it a great flush and fill and while you are there use Redline's Water Wetter radiator additive (great stuff!!!). I've had radiator trouble with other cars before. Usually they stem from negligence of replacing hoses when they start to get inflamed or clamps when they start to fail or get loose, causing surges in the flow/pressure that causes plastic pieces to fail indirectly.

Check out some of these for $80-$150 or less on eBay...

scdroptop, thank you for the links...
I ordered a koyo model from a local distributor with next day delivery. Ebay prices are great but delivery will take 1 week or more...

nice job! Hopefully the local prices were still good and it works. Koyo is a great brand...I had their radiators on my rx-7's in the past which always ran hot.

while you are there, take my advice and do the redline water wetter-it will make your SC run much cooler and also keep your antifreeze more stable.

I had a hair line crack in the lower plastic tank. Lexus replaced it on warranty. The radiator is aluminum except the lower and the top are plastic. Kind of looks cheesy when you see it out of the car.
