You need to let the car run with the coolant system open until it's fully warm. In order to do this without getting coolant everywhere, you need a funnel that can sit with smooth walls against the fill location in the upper reservoir.

The issue is that a whole leg of the coolant system is fed by a pipe that comes out the top of that upper reservoir. You must get the coolant level over the top of that pipe, and that only happens readily by using a funnel. You can half-ass it by squeezing the upper hose and "pushing" some coolant into that area a little at a time, but it's easier to just set up a funnel and let it idle for 20 minutes while you watch TV or whatever.

Alternately you can pull the hose off that pipe, it's the S-shaped hose that goes to the turbo. Fill through that hose and you will get rid of most of your problem.
Just pop the cap on the upper reservoir place a funnel in and let the car idle for a bit? Thanks again guys
