I know there are risers for the manifold that help with heat issues, but I would really like to try some type of coolant system clean, a flush and maybe a 60/40 h20/g13 and see what happens. Right now my fans come on with just a little city driving and I’ve seen heat coming from the hood at times. Driving conditions have been pretty mild and temps are lower than that high 60’s F and even on cool days the fan always manages it’s way on. It’s too hot for my liking.
The previous owner had the rad replaced by the dealer about 7k ago. To me the coolant looks a little dirty and could stand to be renewed; it wouldn’t surprise me if they didn’t flush the entire system when the rad was replaced, but can’t imagine they wouldn’t.
Any thoughts, suggestions would be appreciated. Does anyone have the elsawin page for the flush? Should be easy if I can find the drain…
Anyone used a flush like this? https://www.ecstuning.com/Audi-C6_S6--V10_5.2L/Engine/Cooling/ES2608077/
