No what I meant was, 4Life coolant changes colour when exhaust gasses etc mix with it. So if it's lifting under load only, the coolant will change - this is perhaps can't be picked up under normal conditions with the sniffer test.
I think it's worth doing for such little money.
No its just a colour toyota chose it doesnt change colour and isnt effected by the gasses.
The block test itself does this and when tested it was fine.
