Hello guys, anyone knows why is my heating starts to blow hot air only over 2000 rpm ? I have changed thermostat, flushed coolant system, changed water pump and still no change. Any ideas ??

Was it just the thermostat you replaced? What about the thermostatic valve? Is your engine running to temp?

The waterpumps on these engines only really starts to push the water through in any great volume above 2000rpm

No I didn't change the valve. Engine is working up to temp but looks like it is struggling get to 90 degrease. And only one time happened that it vent over 90. Should I change that valve ?? Do you thing that may be the issue ??

I would, if you say it's struggling to get into temp. I've had similar issues on both my Octi and my fab in recent yrs.
