Replacing coolant fluid

[PonyTrader]

I recently purchased a used 2000 Mustang GT. It has over 90k miles so i thought i would replace couple things since they're probably old. One thing that i want to do is replace the coolant fluid. It seems a little low so do you think i should completly flush it out and put new one or just add more to it and fill it up.

Nah, you should definitely flush it.

Here's a good article for you: http://www.bullittarchive.com/1008.htm

Does your upper manifold have an aluminum crossover? If so, then it's probably been flushed once before. I'd still do it along with everything else. Seafoam, Oil change/oil filter, fuel filter, PCV, plugs, air filter...
