How to Change your own spark plugs
to discover that the cause of these issues was the spark plugs and its wires. Spark plugs are very crucial when it comes to the running of the engine; they work by shooting out some electricity sparks in the engine cylinders which have a mixture of gasoline and air. And by igniting this unique mixture, they it forces the piston to move down thus creating power. These plugs also conduct heat away from the car’s combustion chamber. Therefore they tend to wear down faster since they overheat faster especially with the high-output ignition found in various new models. So if you want to learn how to change the spark plugs please read on.
Changing the spark plugs can be quite tedious if you are doing it for the 1st time, so make sure you set aside at least three hours after your engine has cooled down. Remember it’s a little bit harder than fixing a flat tire or replacing the air filters. So make sure you consult your car’s manual and find out how many gaps spark plugs your vehicle has, the socket size and the gap, before going to the store to look for the right plugs. Visit the local auto-parts store and purchase the right plugs for the car and while there make sure you get the right tools for the job which includes socket-extension rods, spark plug sockets-with-gasket and socket wrenches. Make sure you ask the store’s employee, if the plugs will have to be gapped or not.
Changing the spark plugs
1. Park the vehicle, turn its engine off and open up the hood of the vehicle for the engine to cool down- the plugs are the hottest part of the engine especially if it has been running for a very long time. Therefore it will need several hours for it to cool down completely.
2. Using the wire-gauge plug gap-tool, try to adjust the distance between the 2 electrodes. The sparks are actually created between the electrodes; one of them is L-shaped while the other is a prong-centered directly across the L-shaped metal. Make sure the gap is between 028-060 inches wide.
3. Check if the new plugs fit inside the wrench-socket gasket- if they stick out, remove the gasket using a screwdriver and use a tape instead. Taping the socket to the plugs can make it easy for you to release it once it’s inside the engine.
4. Locate the distributor plug wires using the vehicle’s repair manual- the exact number of cables is always equal to the number of plugs and most often these cables are black or red. Remember they will be equally distributed on the opposite sides of your engine. Make sure you mark each cable with a masking tape, this way you will know exactly where they connect.
5. Remove each plug’s cable by simply pulling the caps- avoid jerking the wires off, instead loosen them by pulling them off intensely.
6. Clean all the debris around all the plugs using either a brush or a compressed-air pressurized engine-cleaner.
7. Remove the spark plugs using a plug socket from the engine and replace them with new ones.
8. Replace all the plug wires on the exact plugs they came from & remove the masking-tape. And finally remove all your tools from the engine and start the vehicle.
