Drain Coolant 2.0 TDI

Featured Replies

Hi Gents,

First post! Hello to all. In the middle of changing heater core and draining coolant.

 

Can anyone tell where this drain location is? Engine is a 2.0 TDI 190PS CNHA

Workshop manual isn't very clear.

 

Thanks,

Scrolling through the manual I found this, states it is the aux pump. Scolling it is under the intake pipe from the airbox. I'll have another look. I did think it was beside the DPF looking at the first image.

True yes.The clip audi suggest is very difficult to get off. You might get it with the proper tool?! The one on the downpipe came off handy enough and it is at the same level more or less. A big screwdriver(mini crow bar) levered against the metal bracket below will get it moving.

I have documented the whole procedure of drain-flush- heater core swap-refill-bleed. Mostly in video from unfortunately 🙂 Will try piece it together and upload at some stage. If anyone has any questions about it give me a shout.

Just to note a bit of H&S, when you do remove that hose, coolant will fire out of the downpipe. At your face if it's in around where the camera is above.
