Doing the coolant for my replacement 4 pot series 3 engine and I was going to use the gallon of red antifreeze that I have handy but it says not suitable for classic cars....not that Yolande is a classic, but is it old enough for red A/F to cause a problem??

I'm pretty sure it needs to be blue.

Has to be blue. Red is only for modern engines that have compatible seals and materials. It will attack brass and incompatible metals.
