Default Radiator Flush

Hey guys,

I have an '06 auto GT vert that has a saleen super charger pushing 415 RWHP and 411 torque. I have about 40,000 miles on it and was wondering when and if I should get a radiator flush?

What's the recommend protocol for this?

Thanks,

Nick

Hey Nick,
If you had this car since it was new and haven't flushed the cooling system yet it's time to do it. I get a bottle of rad. flush and drain a litttle coolant out of the radiator and dump it in and drive the car for couple of days before I flush it. I also replace the thermostat when I flush the cooling system, cheap insurance.
I forget what Ford recommends for cooling system service but I do it every 2-3 years. I put about 8000 miles a year on my cars.

Flushing the radiator? Seriously? I've owned many...many vehicles throughout my life time. Had a few past the 300k miles, so I feel somewhat confident in my way of thinking.

Thermostats stick for various reasons. Sometimes age, other times corrosion. Most modern cooling systems on cars (including the Mustang's system) is considered a closed system that under normal circumstances don't need additional fluid to be added. The truth of the matter, the coolant is formulated to do a thorough job of heat transfer without the "50/50" mixing that generic coolants require. That being said, there shouldn't be any corrosion occurring to mess up your thermostat.

You have had an obvious upgrade to your system which required a fluid draining to be performed. Hopefully factory spec fluid was used to refill the coolant system. That still shouldn't require a flushing unless you or someone else is introducing debris/non-spec fluids into the system.

I know opinions are like @ssh0les and everyone's got one but as I've mentioned, I've owned many cars and a few that have surpassed 300k. If you stick with OEM fluids, you don't need to flush your radiator.
