Even if you're not a car-geek, doing some simple, basic maintenance on your vehicle will keep it out of the shop and extend its life. Here's a collection of 10-minute fixes you can easily do to your car that will save you money immediately or prevent future repair bills.
Coolant doesn't last forever. You have to change it every 24,000 miles (green coolant) or 100,000 miles (extended-life coolant). If you keep driving on worn coolant, expect to replace the radiator, heater core and water pump.
Transfer case fluid and differential oil changes are cheap and easy. Replacing these components will cost you about $1,500 each—a high price to pay for neglect.
A clogged cabin air filter puts an added load on your car's A/C system and reduces heat in winter. Replace it at least once a year.
Test your coolant with a voltmeter. Set your digital voltmeter on the lowest DC setting reading and dip the positive probe right into the coolant. Touch the negative probe to the negative battery terminal and rev the engine to 2,000 rpm. If the reading is .4 volts or more, your coolant is toast.
If you have cloudy headlights, you don't have to replace them or live with them. Clean them with a specially designed kit.
Buy a headlight restoration kit at any auto parts store ($20) and follow the sanding and buffing instructions.
Corrosion puts added strain on your charging system and can mess with computer-controlled systems. Cleaning is your cheapest insurance against electrical problems.
Yes, you can fix this yourself. Pick up a Permatex Quick Grid repair kit ($13) at any auto parts store. Follow the instructions and you'll be defrosting in no time.
An easy avoidable “oops”
Green, yellow, red, orange and blue coolants create cool “mud” when mixed. Cost of a new heater core: $400 to $1,000.
