Who makes a performance radiator for the S550 V6? I see plenty for the GT and Ecoboost, but nothing for us.
You won't need a performance radiator unless you're tuning the car,
and generating more heat in the motor that needs cooled more
efficiently. The radiator is the same for the V6 and V8, the
performance just indicated it's less restrictive and provides more
This rad says is for both V6 and V8, not performance:
Note the upper and lower rad connection points.
This one says performance, GT:
Not the upper and lower hose connections; they're in the same spots, so why can't
you use it?
There are two different EcoBoost rads, I am guessing you mean the GT350 ecoboost
If you check the fitment data for these rads, it still says V6 Coupe 2-Door,
3.7L 3726CC 227Cu. In. V6 GAS DOHC Naturally Aspirated.
I am going to be modifying the engines performance. That's why I'm looking for a performance, or just simply an increased capacity radiator for the V6. Thank you for your information, and I just want to clarify what I believe you had said. For the 2015-17 S550 V6, the radiator used is the same one used in the S550 V8?
After looking on the Ford Parts web site, the V6 and GT share the 'same' part number for the radiator. I have 'never read' about 'overheating' problems because of the radiator being too small on the 2011+ Mustangs, GT or V6.
I wouldn't mess with something that doesn't need messing with :)
You'll probably have to go aftermarket, and compare the thickness and number of
fins per inch -vs- OE, and then if you want plastic side tanks, or aluminum...
More then likely, you're going aftermarket:
Aluminum Side Tanks
52mm, 3-Row core
129% (+77% over Performance Rad) increase in coolant capacity over the stock radiator
26% increase in coolant surface area (tubes) over the stock performance package radiator
55% increase in air surface area (fins) over the stock performance package radiator
Core Length: 25.4"
Core Height: 19.9"
Core Thickness: 2.05"
25.4 x 19.9 x 2.01, compare that with your stock rad: 25.25 x 14.38 x 1.44 in.
