Just wanted to bring this thread up and say thanks Harlie! as it gave me the confidence to rip mine out after having a slow coolant loss for the past few years which turned into a fast coolant loss over the past few months given the range has been parked outside under a carport and its been a cooler winter than usual.

The top plastic egr cooler housing which has the thermostat in it had developed a leak at the rear bolt connection, the one under the oil pipe you cant get at. Took ages to pick it up as it only happens when the car is cold, stone cold, when outside and temps get to 3-6 degree's overnight. Rather disappointed with a well known local landy specialist who miss-diagnosed this leak and another issue with my car also.

Once the fan was off it was all quite easy, only concern is a tiny bit of oil on the air intake, but the car is a bit lighter now and gets upto temp allot quicker. Also happy to see my air intake was allot cleaner than some of the pics I have seen online!
