Getting concentrate is a really good tip if it's true the older engines don't have a drain plug on the engine, that way you can flush it with water, then calculate how much water is still stuck in there and add the concentrate.

Hi Hoonsy,
Yes you do just go to your Toyota Dealer Spares Dept & ask for red coolant.

Also tell them what car you have.
But make sure you get the 'Toyota Red concentrate' that comes in 4 liter containers (that will make up 8 liters of mix).
 
Don't get the 'Toyota pink long life pre-mixed', as I mentioned previously.
 
How many containers you need will depend on whether you only want it for top ups, or whether you want to do a full coolant change.

Don't wanna drain all the coolant completely, feel like I'll do something wrong. So just a top up/bleed air out will do me haha

Thanks for the help fellas. Fingers crossed I do it without any drama :)

Five year change intervals??
My owner's handbook says one year or 20k
 


That's what it says on the (aftermarket product) bottle.  I'm fine with that, as I figure the chemistry has come a long way since my MR2 was built.  I used to use some weird red Toyota corrosion inhibitor additive (closer to when the car was new), which came in 250ml bottles and is long since discontinued, and even that was to be replaced every two years.

Regarding the bleeding of the cooling system, I just wanted to point out something important that no one else ever seems to mention.
Most of us will know that the heater control needs to be set to maximum, and this is always mentioned in how-to guides, BUT in some SW20s (mine included) the heater valve is electronically controlled by a servo motor. This means that you can't just move the heater control slider to full hot with the car turned off. The ignition needs to be on so the servo motor has power to open the heater valve.

There is an extensive build thread for my car here: http://www.mr2australia.com/mr2play/tm.aspx?m=18316
