Cooling recomendations for SC

2004 m3 vert vf570 sc

Hi quick question.

My car seams to be running super hot when going up hills durring hot weather so i plan on doing an overhaul

I purchased an HPF fan clutch and want to replace the thermostat as well as a flush

should i get the oem thermostat or an aftermarket colder one?

Also anyone running the aftermarket coolant?

Thanks.

Keep factory coolant. Make sure its bleed good. And use factory coolant. Its superior to anything you can buy at autozone advanced etc.

If your car has high mileage, I suggest you go through all cooling components.

Unless your going to track your car, I would suggest you stick with the OEM thermostat, aftermarket colder or even the Motorsport thermo has been known to cause the car to throw codes from time to time. Good luck.

Did the fan clutch and/or thermostat help?
