Cooling for my 427LSX TT bad boy! What's best?
In 90*F weather here in California with stop and go driving I am getting up to 232*F coolant temps and not liking it. I am running the AGP race intercooler so that is a big issue. Thinking about 3 things to change.....bigger alum radiator....higher cfm fans and a electric water pump to be controlled by my Pro EFI computer.
Flex a lite had a nice radiator /fan set up that they have now discontinued. So it looks like there is only Mishimoto ($400)or Be Cool ($900) for radiator options for a 2010 SS. Does anyone know of any other options? Also.....can't seem to find any higher cfm aftermarket fan system upgrades either.....anyone know of any? Anyone upgrade their cooling systems????

Aux water pump will get you 4° cooler — when moving, maybe 2 when not — I have a bigger rad (CSF), separate trans (auto) and oil coolers, plus all the hx coolers — still gets to 217° In the summer. More venting of the engine bay and a belly pan would help. I also created baffling to force the air through the radiator.
I’d see if you can baffle the air towards the radiator and eliminate areas where it can sneak around it — bottom, sides, top. Belly pan would help with pressure differences also... I looked for fans, the only thing I founds was a JMS fan booster to run the fans faster at idle — that is another option. It gets hot here too ;o) -Don

Check Ron Davis. I love my heat exchanger. Not cheap.

Before you spend big money on parts, make sure you're directing air through the radiator.
I assume you/your tuner has lowered the fan turn on temps? Sent from my Pixel 4 XL using Tapatalk |

I had a custom radiator made.

Happy birthday Glenn! But hey I dont see coolant temp issues at all and I have the race intercooler, I would assume you have the 160 Tstat? Also running ethanol would help a ton. Get that dex coolant out of there and run all water with some water wetter.

I'm pretty sure the highest CFM fans out are the PWM Spals. Copy Scuzz's set-up.
Aux cooling at the back of the car works great too. Brake up the cool job around the car more. |

Id look at a radiator from the guys at C&R. Also look into the tune. If on e85 richen up the idle and the temps will drop some. im assuming you already have a 160* stat?

Just a note about the guys mentioning running a lower Tstat. If your car is running 230 degrees at idle it does not matter if you have a 120 degree Tstat or a 210 degree Tstat. Directing air flow is a big one. Scuzz that had his custom made has an awesome shroud that makes sure all air from the fans goes through the radiator and not pulled around gaps. A larger radiator can help increasing cooling capacity. Running a longer loop aux set up would fix it but probably be my last attempt. I don't personally like electric water pumps, I like a mechanical pump, just feels more reliable to me.

If you have no risk of freezing you would benefit from straight distilled water and water wetter.

ZX1truth, Scuzz and I are in the same boat; but Scuzz is way ahead of us. I don't have the stop-and-go getting hot issue but if I run at higher RPMs, I get hot 230*F plus. Still stock radiator and fans but did adjust the tune for the fans to come on faster, earlier. I'm thinking I'll try the DeWitt 1-1/2" tube radiator (versus the 1" tube) first, but that fancy shroud sure looks pretty.

This right here works really well. Had cooling issues on a blown 4th gen I had and this solved all my issues. Straight water and 2 bottles of water wetter worked wonders.

I have a steel block, FMIC, upgraded radiator, A/C, etc. I even upped the pulsewidth on the stock fans, until it melted the OEM fan connectors.
When I lived in Vegas, the temps would typically be about 220 w/ A/C. I used distilled water and RMI-25. Even so, my oil temps would climb to uncomfortable numbers.
