This vehicle belongs to my son. It goes from stone cold to extreme hot within 5 miles. He first flushed the system, then we replaced the radiator and the thermostat. When the radiator is open, (with the engine running) you can see that the water pump is working. There is not oil in the coolant nor water in the oil and it is not leaking or missing any of either coolant or oil. The only odd thing is that the oil pressure gage is showing some unusual readings and it has been a while since the oil was changed. The engine itśelf has been rebuilt a year ago (got water in the intake manafold).

I did not do the rebuild.
any assistance would be greatly appreciated.
