Would this be the same for the 16v, or because of the original differences in water setup, it differs. Reason I ask is, when johnny_K had his 16v running, he had the rear plate outlet connected to the water pump rear pipe, as aaron has done here. He never had any over heating issues, if anything, the car ran too cold.
I've run mine like this many times aswell as I've never really had a working heater.
Let us know Sam.
