How do you set timing on a 2002 ford explorer 4.0 liter?

To set the timing on a 2002 Ford Explorer 4.0 liter, you will need the following tools:

* A timing light

* A 10mm socket wrench

* A flat-blade screwdriver

* A Phillips-head screwdriver

* A feeler gauge

Step 1: Prepare the engine

- Disconnect the negative terminal of the battery.

- Remove the air filter housing.

- Remove the distributor cap.

- Remove the spark plugs.

- Turn the engine over by hand until the piston in the number one cylinder is at top dead center (TDC). This can be checked by inserting a wooden dowel or long screwdriver into the spark plug hole of the number one cylinder and turning the engine over until the dowel or screwdriver just stops rising.

- Align the timing marks on the crankshaft pulley and the timing chain cover.

Step 2: Set the timing

- Loosen the distributor hold-down bolt with the 10mm socket wrench.

- Using the flat-blade screwdriver, turn the distributor clockwise or counterclockwise until the timing light flashes when the crankshaft pulley is aligned with the timing mark.

- Tighten the distributor hold-down bolt.

Step 3: Check the timing

- Insert the feeler gauge between the rotor and the distributor cap. The feeler gauge should be able to slide between the rotor and the cap with a slight drag.

- If the feeler gauge does not fit, adjust the timing by turning the distributor slightly clockwise or counterclockwise.

Step 4: Reinstall the distributor cap and spark plugs

- Reinstall the distributor cap.

- Reinstall the spark plugs.

Step 5: Reconnect the battery

- Reconnect the negative terminal of the battery.

Your timing should be correctly set.
