Hey guys, I'm looking for an upgraded radiator for my truck. It was a Max Trailoring Package 6.0 from the factory. Anyways, with the addition of the 428 iron LSX, it runs a little on the warm side on a hot summer day with the A/C on (220 at idle ~200 at cruise) I understand that's fine, but for a race motor it doesn't seem quite right. When its just a little cooler outside under 100 degrees it runs 190 at idle and 183 at cruise which is just right. Fans run just as they should. So I need a more efficient radiator to install. It can't be any wider physically than it is now because the inlet of the turbo is crammed between the light bezel and end cap, but it can be a little bit thicker, or the same thickness as the endcaps with another cooling row inbetween. Can't go too thick or it'll move the fans too close to the hot pipes.

What should I do?

Thanks in advance.

 

maybe try becool additive

 

Change the thermostat
