What causes the engine to run hot?
Engines can overheat for many reasons. In general, it’s because something’s wrong within the cooling system and heat isn’t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Can bad coolant cause overheating?
The wrong coolant or the wrong mixture of coolant and distilled water can cause your vehicle to overheat. Coolant actually becomes corrosive over time, accelerating the wear on the cooling system!

What happens when your water pump goes out?
When a water pump completely fails, it is no longer able to move coolant through the engine; this causes it to overheat. If you see steam, pull over immediately and call your mechanic for assistance — continuing to drive with an overheated engine can damage it to the point that it will need to be completely replaced.
What happens if you run a vehicle without a thermostat?
If you drive without a thermostat, your engine will never reach its optimal operating temperature and your heater may blow cold air. It happens because driving without a thermostat tricks your engine into thinking it is cold outside, causing it to adjust the gas mixing valve and push more fuel to the engine.
