Important Things in Replacing a Car Spark
Before going to how to replace a car spark plug, here are the important things that must be considered.
Before starting to replace the spark plug, there are several important things to note:
1. Use Recommended Standard Spark Plugs
Every car has a spark plug specification that has been tested by the manufacturer. Using standard spark plugs ensures optimal performance and avoids the risk of damage due to inappropriate use of spark plugs.
2. Remember the order of the spark plug wire
In old cars that still use spark plug wires, it is very important to remember or record the order of the cable installation. If swapped, the engine may fail to start or is knocked (shoot).
how to replace car spark plugs according to procedure
To avoid errors that can damage the machine, follow these steps when replacing the spark plugs:
1. Open the hood and let the engine cool
Before starting, make sure the machine is cold. Opening the spark plug while the engine is still hot can cause the spark plug thread to break (DOL) or even break inside the engine block, which will make the repair more difficult and expensive.
2. Disconnect the spark plug wire and remember the order
If the car is still using a spark plug cable, remove the cables one by one so they don’t get confused (documented with photos if necessary). For cars with injection systems, they usually do not use spark plug wires, but coil packs that are directly connected to the spark plugs. In this type of car, remove the coil connector and the locking bolt first so that the spark plug can be accessed.
3. Loosen and remove old spark plugs
Use the appropriate spark plug wrench to loosen and remove the spark plugs one by one. If you want to make sure the order of the cable remains correct, you can replace the spark plugs one by one, that is, remove the old spark plugs and then immediately replace them with new spark plugs before switching to the next spark plug.
4. Install new spark plugs correctly
Use spark plugs according to manufacturer’s standards. Install the new spark plug by rotating it with your hands first to avoid the risk of smear damage. After that, fasten it with a spark plug wrench, but don’t be too strong so as not to damage the thread.
5. Replace the cable or coil
If the car uses a spark plug cable, reattach the cable in the original order. While in the injection car, reinstall the coil and locking bolt, then connect the coil connector.
By following this procedure, the car spark plug will be installed properly and the engine will continue to work optimally.
