Question anyone drain / change coolant?

First off, I did do a search. Then I went to the garage and got the manual to do some reading. Now, I ask of anyone:

Has anyone drained / changed their coolant?

The manual states there is a drainplug on the bottom of the radiator. They suggest having the car cool, opening the radiator cap, then draining the coolant from the drain cap.

Anyone done this?

Greetings,

No. But I have wanted to try it myself. My question is...many autoparts stores sell a "coolant cleaner" product which is supposed to dissolve deposits left in the radiotor by contaminants. Of course the product states that it is safe for all radiators but has anyone tried it? I don't want it to eat a hole in the plumbing.

BTW I plan on using DexCool despite others stating that "once green always green".

Rebel without a clue!!!

Yes, I have drained/filled the coolant several times (once a year).
It's a pretty simple operation. There is a drain on bottom of the radiator, passenger side. Open it up and start it draining, then open the radiator cap (do this while it's cool). Since you're dealing with a plastic drain, be careful not to apply too much torque when you are loosening and tightening.
I also remove the coolant expansion tank to drain and flush it out real good - you'll find some sediment will collect there.
After letting it drain, button it up and refill with a 50/50 mix antifreeze/distilled water SLOWLY. Fill to the full line in the expansion tank too. Start it up, let it run and check for leaks. For the first day or two, check the level in the expansion tank - the cooling system will suck up some of it to replace air that got into the system when you drained.
As for cleaners, I don't know. Since the above procedure doesn't drain 100% of the coolant, I've never wanted to introduce something I couldn't get out. Besides, if you do this every year and the system is clean to start out with, you shouldn't need it.

Thanks for the most excellent information. I am planning on doing it this weekend sometime and it's reassuring to know someone has successfully done it.

Greetings,

RE: coolant cleaner...

The instructions read to drain...flush with water...then the cleaner...then flush with water until it runs clear. Lastly replace with your antifreeze/water mix (50/50 probably isn't the best ratio in Artic North Dakota). I would think that very little would remain in the system if this is done.

Thumbs up

Hell if it's that easy then I'll do mine this weekend. I'll make arrangements with my grandfather tommorrow to use his garage because I have no plans on freezing my you know what

On a lil side note.........Did you know that you can put window washer fluid in your coolant expansion tank and have no ill side affects? Don't ask The only thing I will say is that the person who did it to my car no longer works at the dealership!!!

Don't tell me - when you go to wash the windshield antifreeze sprays out?
(Just another confidence-building story from our dealers)

Bwahahahahahah. Thankfully he didn't top off my windshield washer fluid resevour with antifreeze. That could have been a lil precarious. I really do not know how one could confuse the two caps. I think Subaru made it pretty obvious which type of fluid goes where.
