id rather change it more often I think I'd do this 2 years or something like that.  I don't trust my car enough for longer intervals... will see what colour it comes out next time :)
 

I would use the green stuff for flushing your system out, check it in a week, if dirty empty it and put fresh stuff in.

It should come clean soon enough, and once it has, get nulon red concentrate and distilled water. $50 gets you 10L.

+1 to Red Nulon
thats what I use in mine.

ok sorted the o-ring out.  The o-ring in the car was either worn or completely the wrong size (I'm betting on the latter).  I've been in QLD this week, so got dad to source a new o-ring for me - he ended up with a genuine toyota one.
 
Here's the difference between the two.  (toyota one is bigger)

 
But it's another day, and there's another problem with the car, electrical again.  Drove to buller yesterday, which was fine. But this morning driving to the train station, both my boost gauges went black, my indicators no longer worked, and the turbo timer wasn't working....
 
hoping that I've just blown a fuze and nothing more... will investigate by torchlight tonight....
 
 
 

ok worked out what happened: http://www.mr2australia.c...8489&mpage=1#78513
 
 

It probably wouldn't matter if you didn't bother with the engine block drain plug, so long as you were putting a flush mix thru the system first before adding new coolant mix.
Any old coolant still left in the block would be so diluted it wouldn't matter anyway.
On my 3SGE there is definitely no drain plug on the block anyway lol.
 
As for coolant, why not use the original genuine Toyota red stuff when it doesn't cost much more than other premium brands anyway??

nah its ok I drained every last drop out of the engine - was just a major pain to get off.
 
Also an update:
Got a low torque wrench ordered for the rocker cover.  Will get on and look at finalising the twosrus order this next week so I can get the front sway bar and rocker cover gasket fixed.  It still perplexes me why nobody is selling an alternator cover for 3sgte engines :P would save a few alternators I'd think!
 
I've also ordered a new diode to match the one that I found was disconnected causing yesterday's electrical issue.  I intend on re-wiring (properly) the ignition wires under the dash, so that this problem doesn't happen again.
 
And finally ordered a new dome light LED pack as my old one died.
 
I've got two days off next week (that I'm not snowing) so will look at cleaning the engine bay then. (and installing the other linkages for the DeltaAV shifter cable set I got.)
 
EDIT: also when the torque wrenches come hopefully I'll install the Allen bolts for the rocker cover too - to help slow the leaky engine :P

So did a trip to the snow in the MR2.  Ended up having to put snow chains on, driving through a complete whiteout, sliding all over the place. and my final conclusion MR2s are not designed for the snow. :P
 





 
Got my torque wrench, today, cool little device, will install the deltav bolts in the car when the weather is ok :)

Great pics. Looks like it was fun.
Did you have any problems with the handbrake?
It's generally a good idea to park with it off if you leave it overnight, or it can freeze solid and be a PITA to free up.

i thought of that before i parked it, and parked with it off,  and the car in gear ;) so not a problem with the handbreak.
 
yes was a lot of fun, had to drive along a road that had deep ridges where busses had been, the lowness of the car flattened some of them :P
