Was just wondering if its ok to top up the coolent with water over the summer

Not a good idea. The anti freeze is also a corossion inhibitor, so best use 50/50 antifreeze/water for top ups. Use the same colour anti freeze as is in the car now.

It may just be myth, but are the blue and red ones not supposed to be chemically different?

where can i get brown coolent from

I drained mine,gave it a good flushing,topped up.....still brown. stuff it, it can stay like that

Use distiled water, no tap water for the 50/50 mix.
