The EP-CAMS2604 is a camshaft synchronizer sub-variant for the Ford 4.0L OHV V6 in Explorer, Ranger, and Aerostar for the specific 1996-1997 production period. This unit covers the F67Z-12A362-AAA and -AAB OEM sub-revisions of the 4.0L synchronizer that Premier Gear catalogs separately as CAMS2604 -- a narrower year range within the broader 3-wire 4.0L synchronizer family.

The distinction between CAMS2603 and CAMS2604 reflects Ford's production engineering updates within the 1996-1997 model years. Premier Gear PG-CAMS2604 explicitly covers Ford Ranger V6 4.0L (96-97), Explorer V6 4.0L (96-97), Aerostar V6 4.0L (96-97), F67Z12A362-AAA, F67Z12A362-AAB -- confirming the sub-variant designation for this specific production window.

If you have a 1996 or 1997 Explorer, Ranger, or Aerostar with the 4.0L and the OEM synchronizer shows -AAA or -AAB sub-revision numbers, the EP-CAMS2604 is the correct unit. If you cannot confirm the sub-revision and your vehicle is 1996-1999, the EP-CAMS2603 provides broader coverage.

Application scenarios

1996-97 Explorer P0340 with confirmed sub-revision

Service shops that verify the OEM sub-revision on 1996-97 Explorer and Ranger 4.0L stock EP-CAMS2604 for the specific sub-variant fitment.

Ford 4.0L precise-spec wholesale

Parts distributors carrying both CAMS2603 and CAMS2604 provide complete coverage of all 4.0L OHV V6 3-wire synchronizer sub-revisions.

1996-97 Aerostar 4.0L service

Aerostar owners with the 4.0L V6 and the -AAA or -AAB synchronizer sub-revision use EP-CAMS2604 for the precise-spec replacement.

Installation guide

Verify OEM sub-revision on existing synchronizer: -AAA or -AAB suffix confirms EP-CAMS2604. If sub-revision is -AA, -AB, or -AC, use EP-CAMS2603 for broader coverage. Install using same procedure as CAMS2603: TDC cylinder 1, mark position, disconnect connector, remove old synchronizer, install EP-CAMS2604, use alignment tool to confirm position, tighten hold-down, reconnect sensor connector, clear fault codes.

EP ignition distributor production line

Every EP camshaft synchronizer ships as a complete plug-and-play assembly -- synchronizer housing, integrated cam position sensor, and timing alignment tool included. No additional components are required for direct OEM replacement installation. The alignment tool simplifies correct cam position during installation, preventing the mistimed reassembly that causes immediate engine faults. EP is part of the Ever-Power Group, also producing worm reducers and a comprehensive range of mechanical transmission products.

Frequently asked questions

What is a camshaft synchronizer and how is it different from a distributor?
A camshaft synchronizer is a cam-driven position sensor assembly that replaced the traditional distributor on many Ford EFI engines of the 1990s. Like a distributor, it is driven by the camshaft and mounted in a similar location in the engine block -- but instead of routing high voltage to spark plugs, it contains a camshaft position sensor (CPS) that sends a digital signal to the EFI computer (ECM/PCM). The ECM uses this signal to precisely time fuel injection pulses and ignition firing. On these vehicles, ignition is handled by a separate coil-pack system, not by the synchronizer itself. The synchronizer provides only the camshaft timing reference signal -- but if this signal fails, the engine will not start or will run very poorly with CEL codes P0340, P0341, P0342, or P0343.
Does the EP-CAMS2604 ship with the cam position sensor and timing alignment tool?
Yes. The EP-CAMS2604 ships as a complete assembly including the synchronizer housing, the integrated camshaft position sensor pre-installed in the housing, and a timing alignment tool. The alignment tool is a C-shaped or window-type tool that clips onto the synchronizer during installation to confirm the rotor is positioned correctly relative to TDC before tightening the hold-down bolt. Using the alignment tool is critical -- reinstalling without it can result in a mistimed cam signal that causes immediate engine fault codes and poor running conditions. No additional components are required for direct OEM replacement.
What is the difference between CAMS2603 and CAMS2604 for the Ford 4.0L Explorer?
Both CAMS2603 and CAMS2604 cover the Ford 4.0L OHV V6 3-wire camshaft synchronizer for the 1996-1997 Explorer, Ranger, and Aerostar. The difference is in the specific OEM sub-revision covered: CAMS2603 covers -AA, -AB, and -AC revisions (F67Z-12A362-AA series); CAMS2604 covers -AAA and -AAB sub-revisions (F67Z-12A362-AAA/AAB). These are minor production engineering updates. If you can confirm the specific sub-revision from your existing synchronizer housing label, order the corresponding unit. If uncertain, CAMS2603 provides broader coverage across all 1996-1999 3-wire applications.
What are the symptoms of a failing camshaft synchronizer?
The most common symptoms of a failing camshaft synchronizer include: Check Engine Light with diagnostic trouble codes P0340 (Camshaft Position Sensor Circuit Malfunction), P0341, P0342, or P0343; intermittent no-start conditions where the engine cranks but will not fire; rough or erratic idle quality; hesitation or stumbling under acceleration; poor fuel economy from incorrect injection timing; and stalling at operating temperature. The synchronizer seal can also fail, allowing oil to leak around the housing. On Ford 4.0L OHV V6 applications, the synchronizer is a known high-failure-rate component, and many mechanics recommend proactive replacement on high-mileage Explorer and Ranger 4.0L engines.
What is the difference between the 3-wire and 2-wire cam synchronizer on the Ford 4.0L?
The Ford 4.0L OHV V6 (Cologne engine) used two different cam synchronizer sensor connector configurations during production. Vehicles through approximately 1998 use a 3-wire connector (OEM F67Z-12A362-AA through AC revision). From 1999 onward, Ford revised the synchronizer to use a 2-wire connector (OEM XL5Z-12A362-AA). These two versions are NOT interchangeable -- the connectors, sensor circuit, and housing design differ between the 3-wire and 2-wire generations. Verify your vehicle's production year to determine which version you need: 1992-1998 4.0L applications use the 3-wire design; 1999-2000 applications use the 2-wire design. If uncertain, check the connector on your existing synchronizer before ordering.
How do I install the camshaft synchronizer correctly?
Correct installation of a camshaft synchronizer requires setting the engine to TDC (Top Dead Centre) on the number one cylinder compression stroke before removing the old synchronizer. Mark the position of the synchronizer housing and rotor on the old unit before removal so you can confirm the new unit goes in at the same orientation. After installing the new synchronizer, use the included alignment tool to verify the rotor position matches the correct timing mark before tightening the hold-down bolt. On Ford applications, the leading edge of the rotor's C-shaped vane must align with the timing mark visible through the synchronizer window when the engine is at TDC. Tighten the hold-down to factory torque specification. Failure to use the alignment tool results in a mistimed cam signal that immediately sets fault codes and causes rough running.
How do I order the EP-CAMS2604 for export or wholesale?
EP supports single-unit orders for market sampling, carton quantities for repair shops and parts counters, and container-volume wholesale orders. Standard production lead time is 15-30 days. OEM branding and private-label packaging are available for qualifying volumes. Contact our team via the inquiry form or WhatsApp for pricing and availability.
