I have a 96 Discovery 1 SD, 4.0 engine, 93000 that is running hot. This all started when the water pump failed. Here is a list of what I have done?
Water pump (twice)
Fan clutch
Thermostat (failsafe)
Coolant sensor
Sender unit
Radiator flush and flow check (twice)
System pressure test (passed)
Block test (passed)
Serpentine belt and tensioner
Expansion tank cap
I have tried to purge the system of air using every method available for 3 weeks (lifting front end, lifting expansion tank, blowing through heater hoses, loosening connections till coolant flows?to name a few). I?m not losing any coolant. No white exhaust smoke. No coolant leaks. No noise from heater core (hot air to cabin). After 3-5 mins of operation the guage is already at ? hot (under load). After 1 min of operation the intake manifold is too hot to touch (idle). The skinny hose from the radiator to throttle heater plate is very hot after 1-3 min of operation (idle). The transmission oil cooler pipe from the upper radiator corner (below skinny hose) gets very hot also with 3 mins of operation (idle).

(Could be related) I am getting a P1316 misfire causing excessive emissions, and P0304 misfire. I?m running new 8mm kingsborne wires, +4 plugs and new ignition coils.

Any ideas?
