Campaign 48: Keep It Running
The Complete Vehicle Maintenance, Repair, and Mechanical Sovereignty Guide
A Sovereignty Module of the Practitioner Community
Preamble
A vehicle is the most expensive and most depended-upon machine most people own, yet most people cannot perform even basic maintenance. This dependency creates vulnerability: financial exploitation by repair shops, immobility when breakdowns occur, and inability to assess whether a repair quote is honest. This campaign teaches every Practitioner the fundamentals of vehicle maintenance and repair, from oil changes to brake replacement, from diagnosing warning lights to roadside emergency repairs. The goal is not to make you a professional mechanic but to make you mechanically literate, capable of maintaining your vehicle, performing common repairs, and never being stranded or exploited.
Part I: Preventive Maintenance
Chapter 1: The Maintenance Schedule
| Service | Interval | Cost DIY | Cost Shop | Difficulty |
|---|---|---|---|---|

Chapter 2: Fluid Checks
| Fluid | Location | Check Method | What to Look For |
|---|---|---|---|
| Engine oil | Dipstick (yellow handle) | Pull, wipe, reinsert, pull again. Read level. | Between min/max marks. Golden/amber = good. Black = due for change. Milky = coolant leak (serious). |
| Coolant | Overflow reservoir (translucent tank) | Check level against min/max marks when cold | Between marks. Green, orange, or pink depending on type. Never open radiator cap when hot. |
| Brake fluid | Reservoir on master cylinder (driver side, rear of engine bay) | Check level against marks | Between min/max. Clear to light yellow = good. Dark = needs flush. Low level = worn pads or leak. |
| Power steering | Reservoir with dipstick or marks | Check level | Between marks. Red/pink = good. Dark/burnt smell = needs flush. |
| Transmission | Dipstick (red handle, engine running, in park) | Pull, wipe, reinsert, pull | Between marks. Red = good. Brown/burnt = needs service. |
| Windshield washer | Blue-capped reservoir | Visual check | Fill with washer fluid (not water in freezing climates) |
Chapter 3: Tire Care
| Check | How | Standard |
|---|---|---|
| Pressure | Tire pressure gauge on valve stem. Check cold (before driving). | Match number on driver door jamb sticker (NOT the number on the tire sidewall). |
| Tread depth | Insert penny head-first into tread groove. If you see all of Lincoln's head, replace. | Minimum 2/32" tread depth. 4/32" for wet weather safety. |
| Wear pattern | Inspect across tread face | Center wear = overinflated. Edge wear = underinflated. One-side wear = alignment needed. |
| Spare tire | Check pressure every 6 months | Match recommended pressure on spare or door jamb |
Part II: Common Repairs
Chapter 4: Oil Change Step-by-Step
| Step | Action | Key Points |
|---|---|---|
| 1 | Gather supplies: correct oil (check manual), filter, drain pan, wrench, jack/ramps | Match oil weight and filter to your vehicle exactly |
| 2 | Warm engine 2-3 minutes (warm oil drains better) | Do not run until hot |
| 3 | Raise vehicle (ramps or jack + stands). Never work under a vehicle on a jack alone. | Level, stable surface. Wheel chocks on opposite end. |
| 4 | Place drain pan under oil pan drain plug | |
| 5 | Remove drain plug with wrench. Let oil drain completely (5-10 minutes). | Plug is hot. Oil is hot. Gloves recommended. |
| 6 | Remove old oil filter (twist counter-clockwise). Some oil will spill. | Note filter location before starting |
| 7 | Apply thin film of new oil to new filter gasket | Prevents gasket from sticking |
| 8 | Install new filter hand-tight plus 3/4 turn | Do not over-tighten |
| 9 | Replace drain plug with new washer if provided. Tighten snug, not gorilla-tight. | Cross-threading the drain plug is the most common DIY mistake |
| 10 | Lower vehicle. Add correct amount of new oil through filler cap. | Check manual for capacity. Usually 4-6 quarts. |
| 11 | Start engine, run 30 seconds, check for leaks underneath | |
| 12 | Turn off, wait 2 minutes, check dipstick. Adjust level. | |
| 13 | Recycle old oil at auto parts store (free) | Never dump oil |
Chapter 5: Brake Pad Replacement
| Step | Action | Key Points |
|---|---|---|
| 1 | Loosen lug nuts (1/4 turn) while tire is on ground | Break them loose before lifting |
| 2 | Jack up vehicle, place on jack stand. Remove wheel. | Never work under vehicle on jack alone. |
| 3 | Remove caliper bolts (usually 2, on back of caliper) | 12mm-15mm socket typically |
| 4 | Slide caliper off rotor. Hang with wire/bungee (never let it hang by brake hose) | |
| 5 | Remove old pads from caliper bracket | Note orientation |
| 6 | Compress caliper piston with C-clamp (push piston back into caliper) | Open brake fluid reservoir cap first (pressure relief). Fluid level will rise. |
| 7 | Install new pads in bracket | Anti-squeal shims and clips as provided |
| 8 | Slide caliper back over new pads and rotor. Reinstall bolts. | Torque to spec |
| 9 | Reinstall wheel, lower vehicle, torque lug nuts in star pattern | |
| 10 | Pump brake pedal 10-15 times before driving (seats pads against rotor) | CRITICAL. Pedal will go to floor on first press. |
| 11 | Test at low speed in safe area | Brakes may feel different for first 100 miles (bedding in) |
Chapter 6: Jump Starting a Dead Battery
| Step | Action | Warning |
|---|---|---|
| 1 | Position running vehicle near dead vehicle. Both off. | Do not let vehicles touch. |
| 2 | Red cable: connect to dead battery positive (+) terminal | Red = positive. Look for + symbol. |
| 3 | Red cable other end: connect to running vehicle positive (+) terminal | |
| 4 | Black cable: connect to running vehicle negative (-) terminal | Black = negative. Look for - symbol. |
| 5 | Black cable other end: connect to unpainted metal on dead vehicle engine block (NOT the battery) | Grounding away from battery prevents spark near hydrogen gas |
| 6 | Start running vehicle. Wait 2-3 minutes. | |
| 7 | Start dead vehicle. | If it doesn't start, wait 5 more minutes. |
| 8 | Remove cables in REVERSE order (black from dead, black from running, red from running, red from dead) | |
| 9 | Drive dead vehicle for 20+ minutes to recharge battery | If battery dies again, it needs replacement |
Chapter 7: Flat Tire Change
| Step | Action | Key Points |
|---|---|---|
| 1 | Pull to safe, flat, stable surface. Hazard lights on. | Away from traffic. |
| 2 | Apply parking brake. Place wheel chock behind opposite tire. | |
| 3 | Loosen lug nuts 1/4 turn (tire still on ground) | Counter-clockwise. Use body weight on wrench if needed. |
| 4 | Place jack at vehicle jack point (check manual). Raise until tire is 1" off ground. | Wrong jack placement can damage vehicle or collapse. |
| 5 | Remove lug nuts. Remove flat tire. | |
| 6 | Mount spare tire. Hand-tighten lug nuts in star pattern. | |
| 7 | Lower vehicle until tire touches ground (not full weight). | |
| 8 | Torque lug nuts in star pattern. | |
| 9 | Lower fully. Remove jack. | |
| 10 | Check spare tire pressure. Drive to repair shop (most spares are limited to 50 mph and 70 miles). |
Chapter 8: The Practitioner Vehicle Reference Card
FLUIDS: Check oil, coolant, brake fluid monthly. Oil = life of engine. Coolant = prevents overheating. Brake fluid = stops the vehicle.
TIRES: Check pressure monthly (cold). Match door jamb number. Penny test for tread. Rotate every 5,000-7,500 miles.
OIL CHANGE: Every 5,000-7,500 miles. Correct weight (check manual). Hand-tight filter + 3/4 turn. Never over-tighten drain plug.
BRAKES: Squealing = pads wearing. Grinding = pads gone, rotors damaged. Do not delay brake repair.
JUMP START: Red to dead positive, red to live positive, black to live negative, black to dead engine block (not battery). Remove in reverse order.
FLAT TIRE: Loosen lugs on ground. Jack at jack point. Star pattern tighten. Spare = temporary (50 mph max).
REMEMBER: A vehicle is a machine. Machines are logical. Every warning light, every sound, every smell has a specific cause. The owner's manual is the single most important document for your vehicle and most people never read it. Read it. A mechanically literate Practitioner saves thousands of dollars, is never stranded, and is never exploited.
