This Chilton 26609 repair and service manual covers 2005-2014 Ford Mustang, all U.S. and Canadian models with manual and automatic transmissions.
Note: this manual DOES NOT provide specific info for the Shelby GT500 Cobra or Boss 302 models.
The specific engines covered are:

TUNE UP AND ROUTINE MAINTENANCE
SPARK PLUG CHECK
COOLING, HEATING AND AIR CONDITIONING
NOTE: Spark plugs on 4.6L V8 models are NOT adjustable. If the gap is out of specification, replace the spark plug.
- The gap is checked by inserting the proper-thickness gauge between the electrodes at the tip of the plug (see illustration). The gap between the electrodes should be the same as the one specified on the Vehicle Emissions Control information label or in this Chapter?s Specifications.
The gauge should just slide between the electrodes with a slight amount of drag. If the gap is incorrect, use the adjuster on the gauge body to bend the curved side of electrode slightly until the proper gap is obtained (see illustration).
If the side electrode is not exactly over the center electrode, bend it with the adjuster until it is. Check for cracks in the porcelain insulator (if any are found, the plug should not be used).
NOTE: We recommend using a wire-type gauge when checking platinum- or iridium-type spark plugs. Other types of gauges may scrape the thin coating from the electrodes, thus dramatically shortening the life of the plug.
- V8 engines are equipped with individual ignition coils which must be removed first to access the spark plugs (see illustrations). On V6 engines, remove the spark plug wire from one spark plug. Pull only on the boot at the end of the wire ? do not pull on the wire. A plug wire removal tool should be used is available (see illustration).
- If compressed air is available, use it to blow any dirt or foreign material away from the spark plug hole. The idea here is to eliminate the possibility of debris falling into the cylinder as the spark plug is removed.
- Place the spark plug socket over the plug and remove it from the engine by turning it in a counterclockwise direction (see illustration).
- Compare the spark plug to this chart to get an indication of the general running condition of the engine (see illustration).
WATER PUMP | CHECK
(Refer to Illustration 7.2)
- A failure in the water pump can cause serious engine damage due to overheating.
- If a failure occurs at the pump seal, coolant will leak from the weep hole(s) on the water pump (see illustration).
- Using a flashlight, look for traces of coolant residue or dried coolant tracks around the weep hole(s). If the seal has leaked, it should be very apparent.
- If the water pump shaft bearings fail, there may be a howling sound near the water pump while its running. With the engine off, shaft wear can be felt if the water pump pulley is rocked up-and-down. Don?t mistake drivebelt slippage, which causes a squealing sound, for water pump bearing failure.
- A quick water pump performance check is to turn the heater on. If the pump is failing, it won?t be able to efficiently circulate hot water all the way to the heater core as it should.
