Excellent. You can change the low + high fan settings on the SCT-X3, this is based on eng coolant temps. My low speed fan setting is 204F. High speed fan setting is 210 F.

With a 190 F T stat...and idling in the driveway, 75F outside (+ AC off).... eng coolant hits 204F..at which point the low speed fan kicks in..and coolant temps drop. Once coolant temp hits 194F, the low speed fan shuts off. Then the temp starts to rise...and the process just repeats.

The HE on my 2010 Roush M90 is 18" tall x 21" wide...and gets hit by air from both upper + lower grilles. It's not quite as tall or wide as the oem AC rad behind it. Head temps are typ 10-12 deg F higher than coolant temps. I have 3 x aeroforce gauges on the A pillar. I'm using oem stock eng rad /shroud /fan etc, etc. I did add a 2nd Auto tranny cooler ( B+M) in series with the oem auto tranny rad. Both tranny rads sit in front of the oem eng rad.

What kind of upper grille do you have on the car ? I replaced the oem upper grille on my 2010 with the 7 bar upper grille. Airflow through the upper grille was substantially improved. With either the lo /hi speed eng fan on, I can now feel the air being sucked through the upper grille. oem upper grille on the 10-12 cars is fubar. Its mostly blocked off.

I will revisit the SCT settings today. Im thinking fan on at 180 low and 200 high
I have the 170 T stat

Should see 160ish coming out of the radiator fyi.

Yea we used a laser gun and they were 192 and higher before the fix.
They dropped 30 degrees or so Im thinking.
My son checked and they were 169
maybe 3 degrees dif sitting at idle in the driveway .
So like 175 Ish on the tstat housing and 169 on the lower hose close to the block
Im happy
Now to get the other parts installed that have sat for 2 years
Oh and I got it tuned as well.

Black Intercooler looks nice, Very stealthy. My son even painted the clamps flat black (We could see a little silver shine after installed)
Ill post pics in my build thread today.

Glad you got it figured out! I'd still replace that radiator cap, though...


LOL
I did indeed do that
But My OCD made me switch the caps back and forth to make sure it was not the cap

On another note the original cap would ratchet like a gas cap when installed on the moroso tank, I thought it was normal
The new auto zone capo does not
It just tightens till it stops no ratchet

how does your cap go on?

I only use OEM radiator caps. I've had generic ones go bad in less than 1,000 miles before. I'd go to the local Ford dealer and get a genuine Motorcraft one.
