Since i bought the car new in 2001, i have changed the oil often and made dealer inspections on time, but since i store car in winter, i still didn't flush and change transmission fluid, brake fluid, and the radiator fluid.

Dealer mentioned to me that even that mileage is still low, i should change the things above anyways, because a lot of time passed and the fluids got old.

Will it be best for the car if i change the things above now? And are there any better fluids to use instead of stock fluids?

For example, if i do radiator flush, there is a product from red line oil that you add to the radiator fluid that will help to better cool off the engine, is that any good?

And finally, are there other things on the car that i should service and change now?
