On the 1994-2010 Ford Ranger, the 4.0L V6 uses a waste-spark coil pack with only three coils firing six plugs in paired cylinders, and it has a high failure rate — especially the end of the pack that serves the paired 3 & 4 cylinders (they share a secondary winding). A failing coil makes the misfire jump between the two paired cylinders, throwing P0300 plus paired cylinder codes, rough running and hesitation. Aged plugs and cracked plug wires compound it.

This issue also affects: Ford Aerostar, Ford Bronco, Ford Bronco Sport

Common Symptoms

  • Rough idle / shaking
  • P0300 random misfire plus paired cylinder codes
  • Hesitation and power loss
  • Flashing check engine light under load
  • Poor fuel economy

How to Fix

Swap the suspect coil pack to a different position — if the misfire follows the coil, the coil is bad (replace the coil pack; Motorcraft DG-series). Inspect the coil harness for burnt/frayed wiring, and replace the spark plugs and plug wires with correct Motorcraft parts as a set. Verify no vacuum leak (a lean condition can also set random misfire).

Typical repair cost:$100 - $400

On the 1990-1999 Ford Ranger, the 3.0L Vulcan and 4.0L Cologne OHV V6 engines use a camshaft synchronizer (a cassette that replaced the old distributor) which houses the camshaft position sensor and also drives the oil pump via a gear on its shaft. The aluminum housing receives no forced (pressurized) lubrication, so the upper bushing dries out and the shaft begins to squeal. It is one of the most commonly reported wear items on 1990s OHV Ranger V6s and gets worse with age and mileage.

This issue also affects: Ford Expedition, Ford Explorer, Ford F-150

Common Symptoms

  • Loud chirp/squeal/screech from the front of the engine, usually worse when warm
  • Erratic, intermittent squeaking that mimics a belt squeal
  • On repeat/eventual failure: bucking, stumbling, hard starting or stalling, sometimes with no noise
  • Check-engine light for camshaft position sensor
  • Catastrophic loss of oil pressure if the oil pump drive gear shears

How to Fix

Replace the camshaft synchronizer assembly along with the camshaft position sensor, using the special synchronizer alignment/timing tool so the CMP sensor is indexed to the correct position (mis-indexing throws timing off and causes driveability faults). Enthusiasts strongly recommend a Motorcraft synchronizer over cheap aftermarket units, which have been reported to fail again in as little as 10,000 miles. Because the shaft drives the oil pump, a total failure can shear the drive gear and drop oil pressure to zero, destroying the engine; address the chirp early.

On the 1990-1999 Ford Ranger 3.0L Vulcan OHV V6, the 3.0L Vulcan V6 is notorious for a coolant leak at the aluminum front timing cover. The dissimilar-metal joint (aluminum cover against a steel block) plus pitting/corrosion of the aluminum cover causes the gasket to fail and weep coolant. If the leak is ignored and coolant runs low, the engine overheats, and the 3.0L is prone to cracking cylinder heads and blowing head gaskets when overheated.

Common Symptoms

  • Coolant seep/drip at the front timing cover
  • Sweet coolant smell, low coolant, spots under the front of the engine
  • Overheating if coolant runs low
  • Coolant in oil / white exhaust smoke if a head cracks or head gasket fails

How to Fix

Replace the timing cover gasket (use quality gaskets with black RTV around the large coolant passages so the joint stays sealed against dissimilar-metal expansion, and thread sealant on the bolts that pass into the water jacket). Note that two bolts pass through the oil pan into the cover, so the oil pan gasket is often disturbed and should be replaced at the same time. If overheating already occurred, pressure-test for a cracked head/blown head gasket. Address leaks early to avoid the far costlier head damage.

Typical repair cost:$400 - $1,000
