    Problems with a car's cooling system are usually indicated by a car that generates too much heat, a car that overheats or a car that runs cold all of the time. Check the thermostat and radiator if a car engine is overheating with help from an auto mechanic in this free video on car repair and diagnostics.

    Not bad. Worth noting, though, that the most common cause of no cabin heat is low coolant level. Heater core is usually the highest point in the system, so a little low, and they get nothing. The first thing to do with any overheat/no heat condition is CHECK THE COOLANT LEVEL. It could be empty, and the gauge is reading cold while the engine is melting down because the temp sensor isn't submersed in coolant.

    @gdwordsmith1 It's a VAG (Volkswagen/Audi) problem; The plastic propellers fracture and the shaft just spins inside it, usually followed by a severe overheat with head gasket or engine failure.

    Actually In 32 years of building custom race motors and show cars not to mention the service and repair done at several shops, I have never seen a water pump fail due to losing a fin on the pump, not one!!! most are because of bad seals and poorly maintenanced cooling system.

    I had thermostat, sensors, water pump, timing belt and other small parts replace. The head gaskets are fine. But is still heating up that he water from the resevoir tank boils up and comes out. Help

    A leaky head gasket can also be a reason for no heat inside the car. If your heater core is hot on both hoses and your internal heating controls are working correctly, it may be a blown head gasket that keeps it from heating properly.

    I'm surprised that he didn't mention one of the major causes of overheating....A LEAKY HEAD GASKET. Often a very small leak in a head gasket will cause you to lose small amounts of coolant in the form of vapor. You may smell coolant after driving the car for a bit but you never see it leak. In many cases it just leaks to the outside and doesn't show up in your oil.
