Even though the GT equipment groupintroduced in 1965 was again available fora final year, it was overshadowed for 1969,as the hot ticket was an all-new Mach 1model – wearing the name borrowed fromthose radical recent Mustang show cars.The new Mustang Mach 1 came standardwith the 351, a desirable mix of appearanceenhancements, plus special reflectivebodyside stripes and an uplevel interior.Later, a flat-black rear decklid spoiler anda set of rear window louvers were addedas dress-up options. To many enthusiaststoday, a ’69 Mach 1 equipped with anoptional new-for-’69 428 Cobra Jet V-8 isthe first true Mustang muscle car and atop-shelf collectible.
Other than yet another front-endfreshening (including going back to justtwo headlamps and adding non-functionaloutboard air inlets) and the elimination ofthe side scoops, the biggest change to the1970 Mustang lineup was a move to theCleveland-design 351 V-8 over the Windsor351 version from the year before. The GTmodel was dropped in the face of theMach 1's popularity, but the 428CJ engineoption was again available across theboard. By 1971, Ford’s famedfirst-generation pony car had alreadyundergone its fourth major facelift, growingin every dimension to accommodate evenbigger engines. The ’71 Mustang featuredan extended nose with a body that waswider, close to a foot longer and around600 pounds heavier than the original. TheSportsRoof-only Mach 1 model was nowFord's bread-and-butter enthusiast model,especially with the optional new big-block429 Cobra Jet engine, good for 370horsepower.
There were only minor changes on tap forMustang in 1972 and ’73, most of themdealing with the options list and thecontinuing emasculation of engineofferings and horsepower in the face ofemissions and fuel economy regulations,
as well as the elimination of a convertible.The automotive performance world sooncame to a screeching halt in the wake ofan oil embargo and resulting gasshortages, forcing most Americans toabandon their muscle cars andV-8-powered rides in favor of smaller,more fuel-efficient vehicles. Ford saw themarket shift as the perfect time to returnits pony car to its roots – a compact,affordable, sporty car whose styling andimage captured the spirit and imaginationof the American public.
When the new-from-the-ground-up,second-generation Mustang II waslaunched for the 1974 model year, it wasthe first Mustang equipped with afour-cylinder engine. An all-new 2.3-literI-4 produced around 90 horses as thestandard powerplant for the downsizedMustang II - yet performance was roughlyequivalent to the previous Mustang’s biginline six. The Mustang II was available asa hardtop two-door notchback coupe or athree-door hatchback-style fastback.Buyers had a choice of either I-4 or V-6power, as well as a three-speed automaticor four-speed manual transmissions. Tokeep Mustang’s performance image goingeven in a world where consumers favoredfuel economy over horsepower, anenthusiast-focused Mustang II Mach 1model was offered as a three-doorhatchback-style fastback, replete withbucket seats.
There’s little question that the saving gracefor the Mustang II’s performancereputation came when Ford finally realizedit needed to put the 302 V-8 back onto theMustang option list for 1975-78. The V-8was available in any model, but first onlymated to a three-speed automatictransmission, as a four-speed manual wasdelayed a full year until a suitable clutchcould be tooled up. The two-barrel 302shoehorned into the Mustang II gotcatalytic converters to help meet 1976’s

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or addingequipment to the front of your vehiclecould affect the performance of theairbag system, increasing the risk ofinjury. This includes the hood, bumpersystem, frame, front body structure, towhooks, hood pins, push bar andsnowplows.
Your vehicle has a collection of crash andoccupant sensors. These sensors provideinformation to the restraints controlmodule which activates the following:
•Driver airbag.
•Passenger airbag.
•Front seatbelt pretensioners.
•Adaptive steering column.
•Knee airbag(s).
•Seat mounted side airbags.
•Safety Canopy airbags.
Based on the type of crash, the restraintscontrol module deploys the appropriatesafety devices.
The restraints control module alsomonitors the readiness of the above safetydevices plus the crash and occupantsensors. The readiness of the safetysystem is indicated by a warning indicatorlight in the instrument cluster or by abackup tone if the warning light is notworking. Routine maintenance of theairbag is not required.
A difficulty with the system is indicated byone or more of the following:
The readiness light will notilluminate immediately after youswitch the ignition on.
•The readiness light either flashes orstays lit.
•You will hear a series of five tones. Thetone pattern repeats periodically untilthe problem, the light or both arerepaired.
If any of these things happen, evenintermittently, have the supplementalrestraint system serviced at an authorizeddealer immediately. Unless serviced, thesystem may not function properly in theevent of a crash.
The seatbelt pretensioners and the frontairbag supplemental restraint system aredesigned to activate when the vehiclesustains frontal deceleration sufficient tocause the restraints control module todeploy a safety device.
The fact that the seatbelt pretensionersor front airbags did not activate for bothfront seat occupants in a crash does notmean that something is wrong with thesystem. Rather, it means the restraintscontrol module determined the accidentconditions (crash severity, belt usage)were not appropriate to activate thesesafety devices.
•The front airbags activate only infrontal and near-frontal crashes. Frontairbags may activate in rollovers, sideimpacts or rear impacts if the crashcauses sufficient frontal deceleration.
•The seatbelt pretensioners activate infrontal, near-frontal and side crashes,and in rollovers.
•The knee airbag(s) may deploy basedon crash severity and occupantconditions.

ENGINE COOLANT CHECK
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 449).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not add coolantfurther than the MAX mark.
