Hi everyone. Am doing a coolant flush and re-fill. Previous owner used green coolant so il stay the same.
Whats the best green coolant around thats easy enough to get from supercheap, are the premixes any good or is it better to dilute your own. Also do i need a special anti freeze anti boil mix?

Thanks heaps

The one, the only, Toyota red.

Any coolant will help not boil, Toyota red formulated for the metals within the Mr2 system.

IMO. Best to flush the system, use distilled water not tap, replace your thermostat at the same time (ATS Racing does a high flow low temp should you be running higher boost or track, auto stores do a highflow), replace radiator cap. I like to overdo things and gives peace of mind until kms are done to service again.

Any opinions on Nulon coolant?  and... Green or Red?

I've used Penrite red for the last 4 years...

Its gotta be red OAT coolant, dunno about different 'performance' levels of coolant but from learned knowledge the green has the wrong mystery formula, the red OAT stuff has silicates (or doesn't?!) - or whatever stuff is right for our engines.
 
Green = No.
 
Red   =  Yes.

Drain and rinse the lot of that out, use red OAT, the  premix/concentrate argument comes down to cost, not sure of the top of my head how much coolant goes in as a total, but its more than compared to fwd cars.
 
You probably won't need anti-freeze unless you live in a cold part of the country.

Cool cool. So il flush all the green out and refill with this red one. Anyone know if this will be sufficient, says its good for toyota engines

Thanks

A quick innanet search says you'll need around 13 litres, thats if you drain every drop out. 
 
There's a few drain points on sw's some are easier to get to than others.

Do you think i could just jack the end up high and drain and flush it all out the front radiator? Being the lowest point it should have all of it goin there anyway right. Am i wrong?

You can use anything (see the enthusiast comments above) and it will keep the car cool and appear to be the same colour.
How it reacts with the metals within the Mr2 coolant system is another aspect.
Toyota Red from a Toyota dealership for a Mr2.
Read the bgb, there are drain points to successfully get it all out.
