Hi GXOR,

My 2003 GX470 is ready for a radiator. I'm not buying an Ebay one, it's fine. My goal is to improve engine / trans cooling as I'm always towing my boat and want my truck to remain healthy.

My plan is larger aluminum radiator + racing Tstat (160d) + silicon hoses.

Looking at Mishimoto, Koyo and CSF. Open to opinions between the 3. I know MIshi is the king in the import and performance car world.

These options all have integrated trans coolers, which I like. My main question is does the integrated cooler replace the external trans cooler I have from Lexus? Do you just swap the lines over and send it?
