1971 FORD GALAXIE

Typical onset: 80,000-150,000 mi

Symptoms: Rattling noise from front of engine on cold start that disappears after warmup, Rough idle, backfiring through carburetor, loss of power, Check timing and find it's retarded 8-15 degrees even after adjustment, Complete no-start if chain jumps timing or breaks

Fix: Replace timing chain, gears, and tensioner as a set. Ford's original nylon-toothed cam gears shed teeth over time. Requires front-cover removal, harmonic balancer puller, and new gaskets/seals. 4-6 hours labor on V8s, less if you're not fighting rusted bolts.

Estimated cost: $450-850

Symptoms: Hard starting when hot, fuel percolation in summer, Hesitation on acceleration, flat spots during cruise, Flooding, fuel leaking from accelerator pump or bowl gaskets, High idle that won't drop, stalling at stop signs

Fix: These 50-year-old carbs need full rebuild kits—all gaskets, accelerator pump, needle/seat, and power valve. Heat soak is brutal on original phenolic floats. Figure 2-3 hours for proper rebuild, or swap to Edelbrock. Vacuum leaks at base gasket are epidemic.

Estimated cost: $200-500

Typical onset: 60,000+ mi

Symptoms: Puddles of ATF (Type F) under front of car after sitting, Groaning noise when turning wheel at low speed, Steering feels heavy or notchy despite power assist, Pump reservoir constantly low despite topping off

Fix: Ford Saginaw pumps leak from the pressure seal behind pulley (2 hours to replace). Steering boxes leak at input shaft seal and sector shaft—requires box removal and rebuild or replacement (4-6 hours). High-mileage units develop internal wear causing slop in center position.

Estimated cost: $300-900

Symptoms: Runs hot in traffic or on highway climbs above 210°F, Puking coolant from overflow after shutdown, Gauge creeping past half on 85°F+ days, Fan clutch freewheeling—doesn't pull hard when hot

Fix: 390/428/429 engines overwhelm the standard 4-row radiator, especially with A/C and highway gearing. Original fan clutches fail. Solution: re-core radiator with modern core (3-4 hours with tank swap), replace fan clutch, verify timing isn't over-advanced, check water pump impeller for corrosion. Some need aux electric fans.

Estimated cost: $600-1,200

Typical onset: 70,000-110,000 mi

Symptoms: Clunking over bumps from front end, Wandering steering, excessive play in wheel, Uneven tire wear on inside or outside edges, Upper or lower ball joints show vertical play when pry-bar tested

Fix: Ford used riveted-in ball joints that must be drilled out and replaced with bolt-in aftermarket units. Upper joints fail more often. Requires spring compressor for coil-spring suspension, alignment afterward mandatory. 3-5 hours per side including alignment.

Estimated cost: $400-750

Symptoms: Fuel gauge reads empty, full, or bounces erratically regardless of fuel level, Smell of raw gas around rear of car, Visible rust perforation on top of fuel tank where sender mounts, Difficulty starting after sitting—pump loses prime

Fix: Tank-mounted sending units corrode at the mounting flange and internally. Steel fuel lines rust at frame contact points. Tank must be dropped (2 hours), sender replaced, lines inspected/replaced as needed. If tank interior is rusty, replacement or sealing required.

Estimated cost: $350-800

Typical onset: 80,000+ mi

Symptoms: Late or harsh upshifts, especially 1-2 shift, Transmission won't downshift under throttle, White smoke from exhaust—ruptured modulator diaphragm sucking ATF into intake, Leaking from modulator, pan gasket, or rear seal

Fix: Vacuum modulator diaphragm ruptures and causes harsh shifts or ATF consumption. Replacement is 0.5 hours. Pan gasket leaks require fluid/filter service (1.5 hours). Rear seal jobs need transmission removal (6-8 hours). C6 is otherwise bulletproof—service every 30k miles.

Estimated cost: $150-1,200
