So Fix it

Make sure your Chevy Sprint is completely cool before you start troubleshooting.

Pull the hood latch and open it up. Find the radiator in front of the engine -- it has a cap on it that says "radiator."

Remove the radiator cap by flipping up the pressure release tab on the top of the cap and turning the cap counterclockwise. Set the cap to the side.

Look inside the radiator through where the cap was. Make sure that the water level is to the top. Your Sprint can overheat if there is not enough coolant in the radiator.

Start up your Sprint engine. Make sure the radiator cap is still off the radiator. Look inside the top of the radiator and watch the coolant. Let the engine warm up. When the engine is warm, the water inside the radiator should drop down and then start to circulate. If you do not see the water level change or start to circulate, it is a sign that you have an issue with your thermostat. The thermostat is located in the housing cover where the top radiator hose is connected. You can follow the top radiator directly to this housing. If the thermostat is not opening when the engine gets warm, then your Sprint engine is certain to overheat . A bad thermostat is the most common reason why a Chevrolet Sprint will overheat.

Listen for the cooling fan to come on. When the engine reaches a certain level of warmth, the electric cooling fan will come on to cool down the engine. The cooling fan is mounted on the back side of the radiator. If the fan does not come on when the engine gets warm, then your Chevy Sprint engine will overheat.

Check for coolant leaks. Look on the ground under the engine. Look at the radiator and all the hoses coming in and out of the radiator. If you see any steam or leaks, this is the cause of the overheating problem. Replace any leaking hoses or leaking parts. The cooling system must always be pressurized to work properly.

Let the vehicle to sit overnight to ensure the engine and radiator fluid are cold.

Disconnect the cable for the negative battery terminal with a socket wrench. Put a container under the radiator and open the radiator drain. Wait for the radiator fluid to drain into the container. Seal the container and replace the radiator drain plug.

Remove the undercover for the engine with a socket wrench. Disconnect the bolt from the power steering hose and detach the hose. Remove the drive belts on the engine and support the engine with a floor jack. Disconnect the bracket for the engine mount.

Disconnect the timing belt with a socket wrench. Remove the bracket for the power steering pump and the brace for the alternator with a socket wrench.

Disconnect the mounting bolts for the water pump. Detach the water pump from the water inlet pipe. Remove the gasket from the water pump and discard it.

Clean the gasket surfaces with a shop rag and wet the new O-ring with water. Place the O-ring into its groove on the water inlet pipe. Install the new water pump to the water inlet pipe and tighten its mounting bolts to 17 ft. lbs with a torque wrench. Complete the water pump installation by performing steps 2 and 3 in reverse order.

Fill the radiator with coolant and connect the cable for the negative battery terminal with a socket wrench. Start the engine and allow it to idle until the thermostat opens. Allow the vehicle to cool and adjust the coolant level in the radiator to the correct level.

Turn on the ignition so the instrument panel illuminates but do not start the engine. Note that the needle is in the "Red" area of the temperature gauge, if the engine has overheated.

Open the hood and locate the coolant tank, which is on the left side of the engine compartment. Remove the tank cap by turning it counterclockwise.

Pour 50-50 coolant through a funnel into the tank until you reach the fill line on the side of the tank.

Look under your car for leaks from the cooling system. If you find any leaks, have the car towed to a service shop to patch the leak. Driving your car while coolant is leaking could cause further damage to the engine.

Disconnect the front bumper from the lock carrier with a socket wrench. Remove any electrical wiring needed to move the lock carrier into the service position. Disconnect the quick-release screws from the front insulation panel. Then, remove the air guide between the air filter and lock carrier. Release the retaining clamps that attach the wiring harness to the left radiator frame.

Remove the No. 2 mounting bolts from the lock carrier with a socket wrench and support it with Support 3369. Remove the remaining mounting bolts from the lock carrier and pull the lock carrier out as far as it will go. Fasten 6 mm bolts to the lock carrier and fender to secure the lock carrier in place.

Disconnect the cable from the negative battery terminal to ensure the engine doesnt start while you are removing the cylinder head gasket. Detach the cooling fan drive belt from its pulleys and remove the cooling fan from the engine.

Drain the coolant from the radiator into a container and store for later use. Disconnect the intake manifold from the engine with a socket wrench. Detach the accessory drive belts from their pulleys.

Remove the regulator valves for the wastegate bypass and the evaporative emissions canister from the engine with a socket wrench. Detach the mass airflow sensor from the engine.

Disconnect the housing for the air cleaner with a socket wrench. Detach the wiring harnesses for the engine-coolant temperature sensor and any other electrical components needed to access the cylinder head. Detach the breather line from the crankcase.

Remove the fuel lines and oil line from the cylinder head. Disconnect the heat shield and turbocharger from the exhaust manifold with a socket wrench. Detach the coolant hose from the rear of the cylinder head.

Detach the upper cover for the timing belt with a socket wrench. Turn the crankshaft clockwise to align the timing mark on the crankshaft with the top dead center mark on the crankcase. Loosen the Torx bolt on the timing belt tensioner with a T45 Torx wrench and push the tensioner down to relieve the tension on the timing belt.

Remove the timing belt from the gear of the camshaft, and remove the Torx bolt from the timing belt tensioner with the T45 Torx wrench. Rotate the bracket for the timing belt tensioner forward to access the valve cover and then remove the valve cover with a socket wrench.

Disconnect the mounting bolts for the cylinder head with a socket wrench. Lift the cylinder head from the engine block and remove the gasket from the engine block. Clean the remaining traces of gasket material from the cylinder head and engine block with a gasket scraper. Clean the bolt holes on the cylinder head with a shop cloth and blow them dry with compressed air.
