Accessing The Spark Plugs
Changing the spark plugs on a 2016 Jeep Compass involves several steps. The first step is accessing the spark plugs. This process starts by removing engine covers and identifying the spark plug locations.
Removing Engine Covers
To access the spark plugs, you need to remove the engine covers. These covers protect the engine and keep it clean. Here are the steps to remove them:
- Locate the engine cover. It sits on top of the engine.
- Look for screws or clips holding the cover.
- Use a screwdriver to remove the screws or clips.
- Lift the cover gently and set it aside.
Removing the engine cover will expose the engine components. Be careful not to damage any parts.
Identifying Spark Plug Locations
After removing the engine cover, you need to find the spark plugs. The spark plugs are usually located on top of the engine block. Follow these steps to identify them:
- Look for a row of wires connected to the engine.
- These wires lead to the spark plugs.
- Trace each wire to find the spark plug location.
- There are usually four spark plugs in a 2016 Jeep Compass.
Each spark plug is connected to an ignition coil. The ignition coils are black and cylindrical.
Now that you have identified the spark plug locations, you can move on to the next steps. This will involve removing and replacing the spark plugs.
Removing Old Spark Plugs
Changing spark plugs is a key part of maintaining your 2016 Jeep Compass. Follow these simple steps to ensure your engine runs smoothly. We start by removing the old spark plugs.
Using The Spark Plug Socket
First, gather your tools. You will need a spark plug socket, a socket wrench, and an extension bar. Locate the spark plug wires or ignition coils. Remove them gently to avoid damage.
Next, attach the spark plug socket to the extension bar and wrench. Carefully insert it into the spark plug hole. Turn the wrench counterclockwise to loosen the spark plug. Once loose, remove it by hand.
Inspecting Removed Spark Plugs
Once you remove a spark plug, inspect it closely. Check for any signs of wear or damage. Look for deposits, burnt electrodes, or oil fouling.
Here’s a quick guide to common spark plug issues:
| Issue | Symptoms |
|---|---|
| Carbon Deposits | Black soot on the tip |
| Oil Fouling | Wet, oily appearance |
| Burnt Electrodes | White or blistered tip |
If your spark plugs show these issues, replace them with new ones. Clean spark plugs ensure better engine performance.
Installing New Spark Plugs
Changing spark plugs on your 2016 Jeep Compass ensures your engine runs smoothly. This part covers installing new spark plugs. Follow these steps for a successful installation.
Gapping The Spark Plugs
Proper gapping is crucial for spark plugs to work well. Use a gap tool to measure the gap. The right gap for a 2016 Jeep Compass is 0.035 inches. Adjust the gap if needed.
- Insert the gap tool into the spark plug gap.
- Check the measurement.
- Bend the ground electrode if the gap is off.
