If you have a warm garage, you can do it yourself for about 15$. A Fluid Change is pretty easy Just buy some Prestone Long life antifreeze (yellow). Do a complete drain from your radiator (lower right drain plug)Into a bucket or catchpan. Close the plug. Fill your system with water and run your car for about 10 minutes (IMPORTANT! with the garage door open :-p ). Then do another complete drain. Mix up a 60/40 Mix (60% antifreeze/40% water). The reason I use more antifreeze is so that it can withstand cooler temperatures. I have a tool to measure the freezing point, but find a 60/40 mixture is close enough to withstand -38'C temps.
Once the system is completely drained you can close off the plug, make sure its clicked shut. Now fill the resevoir with the new mixture and give it some time to settle. On the top left corner of the engine you will see a brass screw plug. This has to be loosened to help bleed the air out of the system.
Open the garage door again and start the car up. Loosen the plug and keep the resevoir filled to about 3/4. With the engine running you will see some fluid and bubbles spitting from the bleeder plug. Keep everything going until you no longer see any bubbles coming from the bleeder plug and only a steady and continueous flow of fluid. Then tighten the plug and be sure the resevoire is filled up to about 3/4 full.
You are done. Take the car out for a drive and keep your eyes on the temperature, to be sure that there is no more air in the system. Once you get back, check the fluid level again and top up as needed.
Hope this helps.
PS: If you don't wanna do it yourself any oil change place does an antifreeze change for about 60$.
