New thermostat housing and water pump.

[New2the7]

Just installed a new thermostat housing along with water pump on mk7 GTi.

Is there any bleed valves in the system?

Does the new thermostat have to be coded to the car? Or isit literally a case of plugging it in?

As you can tell I'm new to this platform. And concerned with the stuff I have been reading about component protection etc.

Does anyone know @ what temperature the fans should kick in at?

The dash has been reading dead on 90 degrees c but obd eleven showing 105 degrees c and no fans kicking in.

This is at idle.

The car display will always say 90c unless it's about to overheat. I don't know what temperature the fans are supposed to turn on at but if you want to make sure if the fan is working turn on the AC. When the AC is on the fan is always supposed to run. Your OBDeleven is the correct coolant temperature.

Thanks for you're reply. I have put the AC on and the fans do not come on not sure what my next step should be to fix that?

Check the fuse for the fan. Certainly don't drive it if the temperature is up.

Fuse in the engine bay for the fan is fine. Haven't driven the car as yet as it's a bit of a rebuild project. Any other suggestions? Cheers

Apply power directly to the fan.

The fan comes on when power is applied directly. Maybe I just need to bite the bullet and buy a vacuum bleeding kit

Is anyone able to show me any pictures of there cooling system set up? Especially the pipe which runs along the top of the radiator as both ends of this have been cut and I cannot see anywhere where this pipe would connect too. So in my eyes it's as if this pipe is not being used at all

 

[New2the7]

The pipe in this picture is the one in question

Not sure how much it helps, but I don't have a pipe like that on top of the radiator...

You don't need coding to swap a sensor on the coolant systems. Its only the crash, infotainment & other systems that require coding..The cooling system is not that security protected.

I've not done the 2lt system personally, but I do have the VAG Europe info on it...PM me & I can give you want you need...whats the engine code??

Brilliant thankyou for that

Will fire you a pm thanks.
Did a bit more tinkering and I have managed to get the system working properly. Think I must have had an airlock. As the heaters are now blowing hot air @ idle.
