just acquired this 79 Supra with 30k original miles on it.
The temperature gauge is going higher than needed to be.
I noticed that the radiator was filled with water( red rusty color) and not the antifreeze.
I flushed couple times with water and I filled it with antifreeze, burped the system and I 'm still getting the tempurature higher than normal.
Im leaning towards the water pump being the culprit.
The radiator gets hot so I'm ruling the thermostat out.
Any suggestions or have anyone had the same issue?
your feedback is greatly appreciated.
