OK, we have tested the cooling system on my ae92 fxgt and everything seems to be in order (tested inlet and outlet temps as well after 10 mins of 2-3000rpm)
so it looks like the gauge/ sensor is faulty.
it still shoots up from cold to red hot after about 2 mins of running.
I am fairly confident that i have the right sensor in there now.
any suggestions? or should i just unplug the gauge and run an aftermarket gauge? (not really idea)
cheers
