Radiator Upgrade

[nmraptor]

Has anyone swapped out their OE radiator with an upgraded all aluminum radiator? If so did it make any difference or did you still get the fans on at start up? If you did make the change which company did you buy from and what differences have you noticed?

I don't have a RR but I am curious. Are you having an issue with the stock cooling?

Fans at start up may be a result of the A/C and climate control. Turn the A/C off and see if it still does it.

Not a problem but the trucks run hot and when the fans kick in it sounds like a 737 about to take off (exaggeration). My truck was parked in the sun yesterday and when I remote started it the fans came on immediately and they could be heard across the parking lot. I know changing the radiator won't necessarily stop this from happening but I was curious if anyone had upgraded the radiator and what changes they had noticed.

I would think it would be the first mod given that the oil coolers are both water cooled. It’s tough to determine how much more effective they are based on each manufacturer’s bias. I think the CSF and PWR are most advanced, at least I see them most in the RacecarEngineering magazine.
