Darren ..... the stat in your pictures you say, has a jiggle valve, also the lower disc is smaller than the GTA original stat, It looks very much like a 610 stat with the jiggle valve and smaller disc ......... and temperature rating of 86 degrees.
Can you put my mind at rest please.

As a side effect it would ease the bleeding as well.
Awaiting knowledgeable thoughts in response!

I can see your thinking here on the basis that my current thermostat might be a bit slow, I can seal the thermostat housing, get the temps up a bit higher, retain the secondary function of the other disc, easier bleed for sure and not risk further unnecessary bursts if thermostat is at fault. Question is, when is a jiggle no longer a jiggle?? 2mm, 4mm, ??
I could just get another one too I suppose.

You want to avoid fudging this. A small hole in place of the jiggle is fine, but that's just there to aid bleeding. The stat is there to get the engine up to temp and hold it steady - you won't achieve that with extra holes and you'll run the risk that you never get onto the proper ECU map. Potentially you'll always be on the warm up cycle and you'll be running with extra enrichment etc etc, so all in all sorry but not a good idea. By the same logic that's why you need the stat in the first place, and whilst it can be a useful test to take it out (to check for other issues in the coolant circuit) it's really not an effective fix beyond that.

Cool air from the middle vents is the norm, check the manual for the coloured air diagram and you'll see it all described.
Let us know how you get on with the stat back in place.
