So Fix it

The Chevrolet Sprint was designed with fuel economy in mind. The manufacturer developed the Sprint with only a three-cylinder engine, while the competition was designing cars with four cylinders. This gave Chevrolet an advantage over the foreign carmakers for a while as they scurried to develop vehicles to compete. If your Chevy Sprint has an overheating issue, you can troubleshoot it yourself before you take it to your mechanic, possibly saving some money.

Instructions

1

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

2

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."

3

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.

4

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.

5

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.

6

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.

7

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.

The Ford 6.0 Power Stroke is an eight-cylinder 6.0-liter engine that Ford has manufactured since 2003. It is a diesel engine that Ford most often uses in large vehicles such as 3/4-ton and 1-ton pickups. The function of the fuel injectors is to deliver fuel in a precise timing and quantity. You can replace the fuel injectors on the Ford 6.0 diesel engine without removing the fuel rail, unlike most gasoline engines.

Instructions

1

Remove the valve covers with a socket wrench and detach the electrical connectors from the fuel injectors. Disconnect the mounting bolts for the crankcase-to-head tube assembly and remove the assembly from the crankcase.

2

Disconnect the oil rail from the engine. Push the electrical connector for the fuel injector out of the rocker arm carrier with a small pry tool.

3

Plug the oil drain holes next to the glow plugs with clean cloth. Disconnect the retaining bolt for the fuel injectors with a socket wrench and release the hold-down clamp.

4

Pry the fuel injectors from the engine with a Snap-On SDMT440 Torx tool so that you dont damage the fuel injectors. Discard the O-rings and copper washer on the fuel injector. Pull the cloth from the oil drain holes.

5

Mount new O-rings and copper washers to the fuel injectors. Coat the fuel injector assembly with clean engine oil and install the fuel injector. Attach the hold-down clamp for to the fuel injector and torque the mounting bolts to 24 ft. lbs. with a torque wrench.

6

Place the electrical connector for the fuel injector electrical into the rocker carrier. Lubricate the top O-rings on the fuel injector with engine oil.

7

Install the oil rail into the fuel injectors so that the mounting feet of the oil rail are flush with their mounting surface on the engine. Install three guide bolts to hold the oil rail in place.

8

Install six of the nine mounting bolts for the oil rail. Replace the three guide bolts with the three remaining mounting bolts. Tighten all nine mounting bolts to 10 ft. lbs. with a torque wrench.

9

Connect the crankcase-to-head tube assembly and tighten the mounting bolts to 60 ft. lbs. with a torque wrench. Attach the electrical connector to the fuel injector and install the valve covers.

Starting in the late 1990s, Japanese automaker Subaru installed a 3-liter hemispherical (Hemi) six-cylinder engine called the EZ30 on some of its vehicles -- namely the Tribeca, Legacy and Outback, which is the wagon offshoot of the Legacy. The Outback has experienced problems.

Major Problems

Some Subaru Outbacks of the 2001 to 2003 model years may experience failures of the catalytic converter, air-fuel ratio sensor, knock sensor and/or the cylinder head gaskets. These problems can trigger the "Check Engine" light, and drivers may experience engine stalling, coolant leaks or overheating.

Minor Problems

Although the 2004 Subaru Outback is virtually free of the aforementioned issues, it has an occasional problem with the failure of the oxygen sensor. This causes the "Service Engine Soon" indicator to illuminate, and the vehicle could fail emissions.

Cost of Repair

As of December 2010, MSN.com estimates repair costs as follows: $1,055 to replace the catalytic converter, $200 for the air fuel ratio sensor, $162 for the knock sensor and $595 for the cylinder head gaskets. In some extreme cases related to the aforementioned problems, the mechanic working on the vehicle may need to reprogram the engine control module as well; this can cost an extra $98 for labor. The oxygen sensor is estimated at around $238.
