1. No matter how handy you may be, or how much you think you know about cars, don't make a diagnosis without checking with a qualified mechanic first. If you have problems later, you may void your warranty or ability to exchange the purchased car parts once installed.
2. Rather than rely only on the seller to recommend the right parts, call your local dealer and get the part numbers you require. Some dealers may not give this information out over the telephone. In these cases, call another dealer.
3. Contact the online seller and confirm the part numbers. Do this even if they have the car parts listed for your application (without the part numbers).
4. If you receive parts that look incorrect, do not install them. If you do, you may not be able to exchange them. Contact the seller immediately.
5. Be aware that some car parts have multiple part numbers.
