What causes fluctuating coolant temperature?
One common cause is a defective thermostat, a component that is inexpensive and easy to replace. Other causes of a fluctuating temperature gauge are a failing radiator fan, insufficient coolant level and a leaking cylinder head gasket. A failing radiator fan will be erratic.
Where does the coolant go in a water pump?
The water pump moves the coolant through the coolant passages that are located in the engine. The coolant helps keep the engine temperature low.
How does the coolant flow into the radiator?
The flow of coolant is held back by the thermostat until the coolant reaches the desired temperature, when the thermostat opens up and allows the coolant to flow through the radiator hose into the radiator.
What should I do if my water pump is overheating?
Was raising out of nowhere, so I parked and turned it off, let it cool of 10 mins and turned it back on but it was still hot but the coolant was cooling the engine to normal temp. Then it was fine, it keeps doing that randomly so I replaced the thermostat and the coolant temp.
What happens when you replace your water pump?
Overheating after replacing water pump, thermostat and co… Q: Overheating after replacing water pump, thermostat and coolant temp. Sensor I was driving my truck one day and noticed that the temp gauge was raising as I got home, I turned the engine off and check the engine and noticed that the water pump was leaking, it had a hole on it, how?
What happens if you fill your Radiator with tap water?
A lot of people make the mistake of filling the radiator with regular tap water. The tap water has elements of rust and other minerals in it which can be harmful to the engine in the long run, especially if the water begins to boil and evaporate inside the radiator.

What should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
