Hi,
We need some help bleeding the coolant system on a 1.2 tsi. We recently replaced some parts to the front of the car after a minor bump. Unfortunately the bump was enough to crack the end cap on the main rad and the aux also had a leak.
So we have now installed new rads and went about filling the cooling system. Keeping the cap off and keeping the tank topped up as it pulls the fluid into the system which has worked on less complex cooling systems for me in the past. However I believe these engines have an electric pump for both cooling systems that may require a specific vdcs bleeding routing to help fluid cirulating?
There doesn't seem to be a great deal of fluid making its way out of the engine and into the main rad. The t-stat was operating fine previously.
I dont have a vacuum system or the equipment to run the electric pump cycle but can this be done without? Any tips?
Thanks
David
