Finally got around to adding in a driver's side auxiliary radiator on the CS.
I did some data logging beforehand to do comparison and see what difference it actually makes.
It's a fairly easy install, just 2 connectors (one on the thermostat housing and the other on the main radiator outlet) and a few hoses. All OEM stuff from a Golf R, might do a full write up with part numbers in the future.
No leaks so far just one nightmare of an airlock but that's tomorrow's job!
