Default "Coolant" vs. "Engine Coolant" under the hood

The 2GS is prone to popping and bubbling noises (as many of you probably know) caused by air bubbles and I have heard that the best way to correct this is by adding coolant.

I popped the hood and noticed that there are two different coolant reservoirs- "coolant" and "engine coolant". I bought coolant w/ antifreeze and was wondering which one I should dump it in?

Thanks!

there should be only one engine coolant fill area which is by the radiator cap. Unless you're talking about the coolant resevior. You want to use toyota red coolant and distilled water when filling up. Since a complete flush will take almost two gallon, what I usually do is pour one gallon of water in first and then half a gallon of coolant. Then take the empty jug and pour in 30% coolant and 70% water. That should be good enough. Also, when you are filling the coolant, start the engine so that it circulate the coolant through the engine.

Also make sure you turn on the heater to full heat to get the heater core open. Most of the time having that gurgling noise is due to air in the system. Ever since bleeding the air out, I dont have that noise anymore.

where do you dispose the coolant btw?

also another tip regarding burping, park in an incline,

when i had my SC i filled the fill hole till i cant fill anymore, let it run for awhile and then put the bolt back on. After that i poured some in the over flow tank till its at its correct level.

If your local auto parts dealer wont take it, then you can try taking it to your dealer. Many times they'll accept it if it's just a few gallons.

You can also flush it down the toilet or sink if your city's municipal sewer system allows for it - the plant can handle ethylene glycol but not the heavy metals. Call your sewer company.

Like I said, call up the agency in charge of sewers in your city.

Like George Carlin use to joke about ... NIMBY !!!! Not In My Back Yard !!!! Are you kidding, I don't know of any municipality that openly claims they can handle 'antifreeze' and would even suggest to dump it down the sink. Also, if you're drinking your tap, you really want to dump the crap in your own reservoir? Go dump it in the "next" municipality.... j/k. Don't dump it down any toilet, just bring it to your local conservation center, they'll take antifreeze and dispose properly (hopefully, and not down the toilet).

That's what I usually do - I'll take it to the local hazardous waste dump. And to clarify my post, here's an article saying flush water is OK to go down the drain while all full-strength stuff needs to be handled differently:
