1996 Range Rover 4.6 HSE. I bought it new and have always maintained it myself with the exception of the factory service stuff.

So, I've gone through everything I can think of and am now considering a blood offering to the LR gods. Radiator was pulled and serviced by a guy I've known and trusted for years. New water pump. New viscous fan clutch. New thermostat. New top and bottom radiator hoses. No leaks. No blown head gasket or slipped liners. No oil in water or water in oil. No coolant loss, period. Cleaned the AC condensor. All original fan shrouds in place. The whole system cleaned and cleaned again. I'm running 50/50 distilled water and ethylene glycol and have burped and bled and burped some more. I'm using an OBDII to watch my ECT temperature in real time and the analog gauge is surprisingly accurate as well.

I even jumpered the aux fans at the R13 and R14 relays to run full time as a test and... it still overheats.

I'm about to give up and send it to the shredder. Any suggestions?
