i was wondering if the gs400 can use same radiator as gs300 or is300. im trying to purchase an all aluminium radiator but cant seem to find any online. but read in some forms that gs300 & 98-00 gs400 used same sized radiator.

any help?
tired searching forms didnt find anything.

 

Yes GS300 and GS400 radiator are interchangeable. I just replaced the radiator in my 01 GS300 with an OEM Denso brand I got off eBay for $180 shipped. Perfect fit.

 

Unless you are going for a high HP build, a standard Denso radiator is a great replacement. RockAuto has them for $68 plus shipping for the GS300.

If you compare the GS models in the 1999 year, both have the same part numbers for a Denso radiator.

GS300 - Denso 2213121 {#1640046570}
GS400 - Denso 2213121 {#1640046570}

 

Last I heard, if you want an all aluminium radiator, you'll need to adapt a Supra (or any, but Supra has already been done before) unit.

 

Firelizard is correct. The supra radiator is the same except for the bottom brackets. You just need someone to cut those off and reweld them in the factory GS location
