I think Derren Brown designed the cooling system for TD5s, he's the only guy I know who can screw with your mind to that intensity. So far I've put on 2 new water pumps ( bad mistake trying Britpart ) a new top hose, a new thermostat, new jubilee clips on any hose that looked like it might leak. Its been front flushed back flushed and any sort of flush in between and still it dont work right. Cab heat is intermitent, which I can live with, but still the needle rises nearly to the red, (well occasionally ) when its given some stick........... Still, looking forward to his new series, How to bring on the inset of early dimentia in landrover owners.
