I have the vehicle listed above and it's been overheating. I've changed the water pump, changed the clutch fan, and back flushed the engine and the radiator. Also, took out the thermostat because we don't need it here in Hawaii. What else could be the problem?

Thermostat is for maintaining a certain temperature range within the engine cooling system when it is running and not because when the weather is hot it is not required.

If the coolant is flowing too fast, it would not have time to cool down and continuous running of engine would result in the heat accumulating and temperature increasing.

When does the overheating occur?
Do you have coolant losses issues?
Is coolant being pushed to the recovery tank or is the recovery tank depleting?
