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.Quote:

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.
I will tell anyone how is most proper to change the antifreeze Inn Aveo 1.2.
when I open my cap from the radiator, and it will let all the fluid out of the car, or i must to open some other cap.
Apparently the best way is to remove the lower radiator hose. This doesn't drain everything out though.
Its 13 mm wrench i draining today on Aveo 1.2, but i draining about 3.5 litres and 700ml stayed in engine if i liked to change all coolant how i do thatQuote:

You're right, but if I want to change the all antifreeze in the car, because I had a G11 in my Aveo and I want to replace him with the G12, i must release all coolant from my car.Quote:

yes, you can pressurize the system to blow more out, also remember the heater core (try starting the car and turning the heat on).
If you want to be sure you got it all out, flush the system a few times through with water. Even if you leave water in there and drive around a few hour (watch your temp) and then drain, and repeat. until it comes out water. Then your system is as clean as can be to make the change.
One question i have is how did you have g11 in the car and not dexcool (gm) coolant? from my understanding, i dont know the year of your car, but the most recent dexcool is g12 compliant. but that is tech talk from msds sheets ingredients, not supplier based.
My father put a G11 instead of G12 and I had to change the all antifreeze, antifreeze was low under the minimnum, and my father put G11,not good a
ah, ok. yes then you definitely need to pressure flush the system to clean out the heater core.
On my Aveo 2004 LS the drain plug is located on the passenger side of the radiator near the bottom. It is 13mm and plastic so be careful not to strip it. I removed the passenger side radiator fan to access it more easily. This is done easily by removing the 10 mm bolts at the top and disconnecting the electric wire. It pops out from a clip in the bottom.
Raising the driver side of the vehicle about 10 inches will completely drain the radiator
For letting everything out, it's pretty closed. Neither the engine nor the reserve tank drain because of the thermostat being closed overnight (I hope you're not doing this hot.) Don't pull the drain plug all the way out, there's a rubber nozzle directly under it that is the actual drain. Don't push hard on the wrench on it either, because it's plastic. I imagine that the shop will pull of thermostats and all hoses to get everything drained, but that's more than I have time for right now. I'm on the way to replace the water pump, so that might get me completely empty below the thermostat.
Passenger side my ass... its on the very bottom at the drivers side just under the axle frame inconveniently ledged with no f***in space to remove... its a plastic nut which is a pain in the bumper to take off... not doing this crap on my own ever again!!Quote:

After looking it up online for hours, finally figured out where the drainage plug was even located! It can be found on the drivers side directly behind the "grill" or "fascia." There is a small rubber "nipple-like" spout where the fluid will drain from and the plug is directly above it. There is no need to take the plug completely out, but just loosen it until it drips. Make sure you keep the cap on the reservoir until you're out from underneath the car. I used a very small 13mm wrench as there isn't a lot of room to work in that area. Reason for posting is that it was a huge piss off to locate, and a post like this one could've cut my time in half! Pics attached!
Right in the middle it is 13 mm. Having read all the posts here, i guess on some newer aveos it is accessed from below the bumper on the driver's side (LHS)
Thanks dragonwarrior2016, is this still true? no drain plug for your 2006? Trying to find it for my 2010 Aveo LT
