How to save money and restore engine performance by replacing worn spark plugs yourself. Quick no nonsense guide gets you there with torque specs, socket sizes and correct spark plug numbers for 2002 Mazda Protege.
Some people still insist on using anti-seize, but I have never used it on plugs and in over 40 years of changing them have never had a problem. Its great when the manufacture recommends not using them. Thanks for the shout out and for watching.
Excellent video. Step by step on what to do. I did this on my 2003 Mazda Protege today (Nov 11) and it is exactly the same. A very satisfying repair job. Thank you for sharing.
Protege and Mazda 3 are pretty easy to work on, although schedule maint is more freq on older models. If you do all the reg maintenance it should last you a long time. Thanks for watching.
@@tanoktenahua1665 In the past I have owned a 1988 Mazda323 (14yrs) and 2005 Mazda3 (13yrs) and they were both carefree. Just do the regular maintenance and these well built cars will last a long time. The Protege in this video is still running strong, although after 18yrs it could use a new power steering pump. Do note that older cars like 2002 require more frequent scheduled maintenance then a 2005. Hope this helps.
Good video but you should let people know that the boot at the end of the spark plug cable could be missing and dry rotted down by the spark plug and if you don't dig that out you will NEVER get you socket on the spark plug to get it out....
You should change the description to say "restore" engine performance. Not upgrade, since changing spark plugs doesn't add horsepower it just restores it compared to having worn plugs in there.
If there is oil on plug tip and thread it could be a sign of a leaking valve cover gasket, failed O-ring, worn valve guides or other serious problem. Best to have it inspected to determine the cause.
Well unlike my old car I don't think I can do this one on my own. Can someone give me a heads up on what this should cost with a reputable mechanic? In other words not the Dealership
Tanya it really is very simple if you break it down to little steps. That being said if you are not handy with tools then a friend or mechanic might be the better choice. Ask your co-workers and friends for references. Good luck with the project.
Great video! Very clear and to the point. I´m planning to change my spark plugs soon. Just don´t know if I should take the cooler of hotter ones. What´s your advice on that? What reasons do you have for choosing the cooler type?
Thank you for the feed back. I always buy what the auto maker recommends. If the particular plug is discontinued then I look at the recommended plug manufacturer for the proper substitute. The only reason you would switch to hotter or colder spark plugs would be if you modified the original engine performance. A colder plug would be the choice for a high performance engine because they generate more heat and the colder plug would allow greater heat transfer to the engine.
Thanks for answering. My user manual recommends two types (a hotter and cooler one). I think I´ll go for the hotter ones than (lower NGK number) as I drive the car in a relaxed way and my climate is pretty moderate. Thanks again!
Here is what NGK says: NGK spark plugs feature what is known as trivalent plating. This silver-or-chrome colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without the use of anti-seize. NGK tech support has received a number of tech calls from installers who have over-tightened spark plugs because of the use of anti-seize. Anti-seize compound can act as a lubricant altering torque values up to 20 percent, increasing the risk of spark plug thread breakage.
Giving the same car different names throughout the world is common. I guess marketing determines what name resonates with different regions of the world. Still glad you found this video and hopefully it was useful.
