BIRMINGHAM, Ala. (WIAT) - A nationwide Angie's List poll found 32 % of respondents change their oil as recommended, but skip regular service checks.

Experts say when you're looking for a mechanic, start with a small repair to build up trust so you feel comfortable down the road when bigger issues arrive.

According to auto shop owner Robert Waeiss, there are several things you should have checked out to make sure your car is ready for winter.

"The big things to look at during the winter in antifreeze make sure the coolant isn't freezing and ruin the engine. Battery, you want to make sure you have a good fresh battery a strong battery to start it in the really cold temperatures. Then of course tires, good tire tread and good tire pressure that's going to keep you as best you can from slipping down the road."

Some signs there may be a problem with your car include oil spots or green liquid leaking from underneath, excessive vibration when driving, or if the car is running unusually loud.

Look for these warning signs that your car may need inspection or repairs:

•Warning light indicators: If the “Check engine” light or “Service Engine Soon” light illuminates on your vehicle’s dash, call your mechanic.
•Squealing or grinding sounds when coming to a stop. This can indicate your brake pads; rotors or calipers are on their last leg and need to be serviced as soon as possible.
•Oil spots under your car. An oil leak can be dangerous to your car’s lifespan. Without proper lubrication from oil, your car's performance is undermined and the engine can eventually lock up.
•Green liquid leaking from your engine. The manufacturer for safety usually dyes radiator coolant, which helps maintain engine temperature, green. If you have a coolant leak, your engine could overheat, which can mean thousands of dollars in repairs. Leaked coolant can also poison pets.
•Slow starting. This could mean that your battery is dead or dying.
•Excessive vibration while driving. If your car is vibrating more than normal it could be a sign that you need new tires or your tire alignment adjusted.
•Car is running unusually loud. This could be an indicator that you need a new muffler.
•Squealing noise when you start the car or turn on the A/C. This could be the sign of a bad serpentine belt, which helps provide power to essential components such as the power steering, water pump or alternator

Angie's List Tips for finding reliable car repair:
•Find a good shop before you need one: Don’t wait until your car is on the blocks to find a mechanic. Doing your homework and developing a long-term relationship with a mechanic/service shop will help you avoid being rushed into a last-minute decision. You'll also be first in line for emergency service and cost savings.
•Specialty service: A full-service shop may be able to handle most of your needs, but if you need a highly specialized service, do some research to find the right specialist. If you have a good and long-term relationship with a full-service shop, you'll likely find at least one good recommendation there.
•Read and follow the manual: If you read nothing else in the manual that comes with your car, read the preventative maintenance schedule about tires and follow it. Know what type of tires your car has.
•Get it in writing: Get a written estimate before authorizing repairs. Request that all replaced parts be returned and insist on a detailed invoice of work done, including an itemized description of parts and labor charges.
•Check licensing & certification: State or local law may require that a shop be licensed or registered. ASE (Automotive Service Excellence) certified mechanics must have two years of experience and pass an exam to become certified.
•Warranty work: Determine if your warranty requires you to use a specific dealership or shop. If you use another source, keep all receipts in case your warranty coverage is questioned.
•Diagnosis: Many auto service shops charge a diagnostic fee to determine what ails your vehicle. Some may reduce or forgive that fee if you have the work performed there. Always ask why a repair is needed.
•Get a second opinion: On expensive or complicated repairs, get a second estimate. If you decide to have the work performed elsewhere, be aware that you may have to pay another diagnostic charge.
•Before you leave the shop: After repairs are finished, get a complete repair order that describes the work done. Ask to see any old parts. Some states require mechanics to give you any parts they have removed from your car unless the warranty requires they be sent back to the manufacturer.
