Replace Your Wiper Blades

DIY Savings: $20

Its easy to tell when your blades need replacing. Simply press the washer button and see if they wipe the windshield clean. If you see streaks, the blades are done. The auto parts store will have lots of economy blades, but get a name brand instead (such as ANCO, TRICO or Bosch). They cost more, but their higher-quality rubber wipes better, has better UV protection and lasts longer. Follow the installation instructions on the package. Be sure you have a firm grip on the wiper arm once you remove the old blade. If it gets away from you, it can hit the windshield with enough force to crack it.

change power steering fluid

Change Power Steering Fluid

DIY Savings: $55

There arent any test strips for power steering fluid, so youll have to rely on the manufacturers service recommendations or general rule of thumb (two years or 24,000 miles). Use the turkey baster method to remove the old power steering fluid. Suck out all the fluid (engine off) as shown. Then refill the reservoir with fresh fluid. Start the engine and let it run for about 15 seconds. Repeat the fluid swap procedure until youve used up the full quart.

Note: Never substitute a universal power steering fluid for the recommended type, and never add miracle additives or stop-leak products. They can clog the fine mesh filter screens in your steering system and cause expensive failures.

You cant do a complete brake fluid flush yourself, but you can do the next best thinga fluid swap. This procedure will introduce enough new fluid to make a difference.

Use a baster to suck out the dark brown brake fluid (brake and power steering fluids are incompatible, so use a different baster for each). Squirt it into a recycling bottle. Refill the reservoir with fresh brake fluid as shown. Then drive the vehicle for a week to mix the new fluid with the old. Repeat the procedure several times over the next few weeks until the fluid in the reservoir retains its light honey color.

Note: The brake fluid may damage the basters rubber bulb, so dont suck the fluid all the way into the bulb.
