Transmission Overhaul:
Detailed instructions for the overhaul and repair of both manual and automatic transmissions.
Electrical Troubleshooting:
In-depth troubleshooting for electrical faults, utilizing wiring diagrams and diagnostic tests for sensors, actuators, and control modules.
Depth:
Comprehensive, covering everything from basic maintenance to complete component overhauls and advanced diagnostics. Designed for professional technicians and skilled DIY enthusiasts.
Oil Change Interval:
Typical recommended oil change interval for the 1996 Protege is every 5,000 to 7,500 miles (8,000 to 12,000 km) or every 6 months, whichever comes first, depending on driving conditions. Always consult the manual for specific recommendations.
Engine Oil Type:
For the Z5 and BP engines, SAE 5W-30 or 5W-40 synthetic blend or conventional motor oil meeting API SG or higher is typically recommended. Always verify with the specific manual or oil cap.
Coolant Type:
Ethylene glycol-based antifreeze coolant, typically a 50/50 mixture with distilled water. Mazda typically uses their FL22 coolant or a compatible equivalent for newer vehicles, but for this era, standard green coolant was common.
Automatic Transmission Fluid:
Dexron III or equivalent ATF is typically specified for the FA4A-EL transmission. Verify with the manual for exact specification.
Manual Transmission Fluid:
GL-4 75W-90 gear oil is commonly specified for the F25M-R manual transaxle.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Common Protege Issues:
Common issues for this generation can include timing belt service intervals (critical for interference engines like the BP), occasional EGR valve clogging, minor oil leaks, and wear on suspension components like bushings and ball joints. Clutch wear is also a common maintenance item.
