Absolutely love your vids, so in depth and informative, just curious, is this the thermostat that opens at 60 with Piwis or about 90 without? If so, it has a electrical connection, obviously sending a dc voltage to open, if the same connector could be sourced could you in theory open this circuit with applying the voltage signal with a source and bleed the cooling system without even starting the car?
Yes that's the one. It opens with no DME intervention at 105 C. The coolant pump needs to be going to bleed the system. Opening of the thermostat earlier just allows the coolant to be pumped through this part of the system earlier to help the bleeding. I considered hooking up an electrical signal to open it earlier, but after playing with it I think it's far easier to bleed like I show in the vid I made of this.
@@jeffrichardsoncardiy Any idea of the voltage that needs applied? Just annoying having a car sitting idling for such a long period of time :-( would you agree in theory that it could be done as soon as the car is turned on if that valve could be opened with a signal? Again thanks for the reply
@@beano6584 It's probably a PWM 12V signal. If you were actually considering doing this I'd suggest thermostat removal and testing to see what you got from a simple 12V application. Also, if you disconnect the plug, or the pins at the DME so you can apply the voltage, you will have errors appearing which will then need to be removed. You need to run the car for a good while to do the bleeding, as there is more to it than simply opening the thermostat. You are removing the air from the entire system, and opening the thermostat is just one part of this.
@@jeffrichardsoncardiy Thanks again for the in depth explanation! I have a different thought about injecting a 12V power to open the thermostat earlier than its normal temperature opening. It's just my hunch that the car allows extra cooling when the sports mode is selected. I'm guessing the DME is sending a signal / power to open the thermostat at a lower temperature. Do you know if that's the case? Thanks!
