      Coolant drain plug

      One of the few things I didn't get done with the engine the other day was draining the coolant out of the block. For the life of me I couldn't find the drain plug for it. I looked in the service manual (admittedly fast), but still couldn't find it. Am I going blind or is there no drain?

      look at the passenger side radiator tank and you'll see it. you'll need a 12 or 14mm wrench (been 2 years since I changed my coolant).

      So thats the only one eh? Well, the engine is out of the car anyways, so coolant is gonna come out one way or another.

      I recently replaced the radiator on my 2006 Aveo and it does not have a Drain plug the only way to drain it is to remove the two hoses that connect to the car.

      When I called the dealer and asked them what else I should do at 30k besides the plugs and they suggested I flush (drain/fill) my coolant. How important is that? Does it have to be done every 30k? Any coolant better than another? (I'd rather get high quality stuff in there if there is such thing and let it sit in there for longer and not worry about it)

      For the sake of your water pump I suggest the coolant every two years. These cars use conventional coolant and it's corrosion properties start deteriorating after 2 years.

      another thing I'll have to do. Can I upgrade the coolant or once they pick a kind - it stays that way? I've seen "upgraded" Amsoil coolant recommended for our cars when you look them up on their site, has anyone done that yet?

      if you fully flush the system, you can.. i personally would run straight water for a bit (since its summer) just to clean any sludge or build up.

      If you run the yellow coolant, it is compatible with both and supposedly has all the benefits of dexcool.

      vw coolant is excellent as well, you have to buy it from the manufacturer though. if you are flushing the whole system to change coolant types anyhow, might want to research what options are out there and pick the best i think toyota has a good one too..

      Alright, finally doing some work on the Aveo again. I still have water in the coolant system since the rebuild. Of course its getting colder out now and its time to replace that with coolant. I drained all I could through the plug on the radiator and thats only about 1 gallon of liquid. Is there any way to completely drain the coolant system?

      Edit:

      Looks like the coolant capacity is 7.4 quarts. I drained about half that. I guess I'll just pour in pure coolant and that'll give me close enough to a 50/50 mix.
