Coolant drain and fill
Ive got about 60k on the clock and not sure if the coolant has ever been replaced or flushed. Ive read that it is hard to get all the air out after a flush. How difficult is it to drain the radiator and fill it back up?

It's not a difficult job at all to drain and refill the rad in these cars, I just did that myself last summer, using the instructions on here on how to make sure the air got out of the system when I was done. I didn't bother doing a complete flush of the system, what I ended up doing was draining the rad and refilling it 3 times over the course of 3 days. I figured that was good enough to get 90-95% of the original coolant out of there.

The link DeeGee provided is the one I used to change mine....
The only issue I had was that someone must have changed my radiator drain plug. Mine does not turn and tighten, it has a silicone rubber "O ring" press in /pull out plug

drained mine last weekend. Old solution was very clear. Refilled with 50-50 Dexcool and distilled water. Drove it for a day and topped it off with about another half gallon of 50-50 mix.
Good for another 5 years.

It's not a hard job at all as mentioned above!
Just be patient and it'll go smooth, get yourself a large low profile plastic container to catch the liquid.
What works good for me is that I have th EWP (Electric Water Pump) and I can circulate the fluid and get rid of the pockets of air easier. So take yours for a drive and if you check the fluid while it's "HOT" make sure you leave the motor running so it does not blow up in your face and leave you burned.
Thanks,Matt

Check your drain plug
Be careful you may have a bad plug. The plug should have a pin sticking out the side of it and it easily breaks off (mine did). The pin rides in a spiral slot. As you push the drain plug in and turn 1/4 turn clockwise at the same time, the pin holds the plug in position. Without this .080" dia pin your plug might come loose. If you jack up the car and get your head up under the rad and look closely with a light and see if you don't see the spiral slot on the outboard side of the drain plug.
