Ford Explorer Alternators and Generators
Initially designed as a small compact SUV, the Ford Explorer has gone through five generations since it was introduced in 1991. Replacement alternators or generators are specific to Explorer model years and engine specifications. Alternators for the Explorer may fit a V8 or V6 engine configuration, and will vary depending upon the cars generation and model year.
Can a Mercury Mountaineer alternator fit a Ford Explorer?Mercury Mountaineers are the twin vehicle to the Ford Explorer and were made between 1997 and 2010. The Mountaineer and Explorer alternators will match as long as the car model years and types of motor configurations are the same. A remanufactured alternator or generator from a 1999 Mercury Mountaineer with a 4.0L 245 cubic inch V6 FLEX single overhead cam motor, will fit a 1999 Ford Explorer with the same engine.
What is the difference between standard and heavy duty alternators?A Ford alternator is rated for a level of performance that is either regular or heavy duty. Standard alternators and generators for older Ford Explorers are usually 90 amps, but the Explorer Limited has an alternator rated for 130 amps. Specialty vehicles for off-road or towing or that need to produce electrical energy during extreme weather conditions also use heavy duty alternators. Fifth-generation crossover SUV Explorers made after 2011 have 200 amp alternators.
What performance needs could require a higher amp alternator?When equipment is added to an Explorer such as aftermarket sound systems, lighting systems, drivetrain modifications, or custom heating and air conditioning, more amperage is needed to generate sufficient electricity for proper vehicle operation. Ford Explorers that used original 90 amp alternators and generators may be fitted with 175 amp alternators to keep power going smoothly under all operating conditions.
What are OEM, NOS, and aftermarket alternators?OEM, or original equipment manufacturer, alternators and generators are replacement components that have been manufactured to Ford specifications for the Explorer powerplant size and model year. NOS or "new old stock" parts are original Ford parts for the vehicle that have been stored and not used, from 1990 onward. Aftermarket alternators and generators may be made to provide additional electricity for specific vehicle modifications and needs. Their performance and ratings will be certified by organizations like NSF or CAPA.
What are high output Ford Explorer alternators and generators?High output alternators are manufactured as aftermarket parts for Explorers from 1991 to 2010 and are made to fit different power plant configurations and model years. This type of alternator can be an upgrade to an Explorers electrical system. A 1991-2001 Explorer with a 4.0 liter motor has two options: 200 and 250 amps. A 2006-2010 Explorer with a 4.6 liter motor has options for 200, 250, and 320 amp high output alternators.
