Trip to the local garage to get the offside steering gaiter replaced , after the heads up during the MOT. Unfortunately the whining sounds like it is the differential, which is a BTR limited slip from a Holden. I will need to decide whether to have it reconditioned or to get a new one (no idea what they cost or availability). Either way the car will have to be off the road for a few days at least in the near future.
I also finally got round to talking to Jay about the cooling. Why?… With both fans on, there is substantial airflow from both wheel arches. The kidney grills at the rear of the bonnet are too hot to touch even in Winter & at slow speeds.
So… How to get more heat away from the engine?
