Colin,
When you run the engine, check to see if air is drawn in the front or blown outwards. If blown outwards, it still has the reverse flow fans and you should retain the front shroud or change the fans for the conventional ones, else you will overheat very quickly, especially where you are situated. This vehicle appears to have its ducting still in place, it is the large box section going either side of drivers hatches, this is where the hot air is evacuated on a conventional airflow system.
regards, Richard
