Due to a high volume of off topic posts the moderators can't always provide you with individual notification and guidance of moderation actions.

Content Guidelines

1. Please be polite. Treat those asking for help with respect, and answer without bias toward them, their situation, or their knowledge (or lack thereof) about the repair issues. Also respect those that take the time to answer questions and remember that many are professional mechanics, who normally get paid very well to diagnose automotive repairs.

2. This subreddit is only for specific DIY mechanical-type car repairs. "X is broken, how do I replace it?" "Y is making noise, what should be inspected/replaced to resolve it?" We're here to help you fix your car on your own, not to assist in negotiating with mechanics (this is business/life advice, not car advice) or to perform non-repair related modifications (you're better off finding a manufacturer specific forum).

If it's under warranty don't post here: bring it back to the dealership.

Some examples of things that are NOT ALLOWED: links to articles, bodywork repairs, detailing or cleaning questions, aftermarket car stereo questions, car reviews, new & used vehicle recommendations, price comparisons for tires, stereos, exhaust, etc, or parts searches (where do I get a ...?) and especially questions regarding cost of repairs or the legitimacy of a mechanic's quote.

Remember that posting here is not a substitute for using google.

We've started a subreddit for general tech, articles, and recommendation posts over at r/cartech. If you still aren't sure about something you are about to post, please look at the links below for other subreddits that would be better suited for your non-mechanical repair question, or message the moderators for suggestions.

3. Have as much information as you can about the issue before posting. Attempt to investigate the repair issue on your own. Take pictures, crawl under the car, look under the hood. By making a good attempt to narrow down where and what may be causing the problem you save those trying to help many steps in diagnosing the problem. Be sure to also include the year, make, model and engine size of you car in your title, along with your main issue. For example "2003 Ford Crown Victoria 4.6L exhaust manifold bolts rusted off" would be an acceptable post title. If you do not take the time to include this basic information your post may be removed until it is revised.

4. Get OBD codes! If you have a Check Engine or Service Engine Soon light on, get the codes read and have them available if possible. You can have codes read at Auto Zone, Pep Boys, O'Reilly's, etc. for free in most states. Write them down. They will have a letter followed by four numbers, for example "P1234".

5. Report posts and comments that fall outside the guidelines. By actively helping the moderators with this you ensure that the r/Cartalk community continues to be a worthwhile and knowledgeable resource for car repairs.
