Engine UZAM 412

Symptoms:
- Engine overheating during operation
- Poor fuel economy and reduced power output
- Rough idling and stalling at low RPMs
- Excessive oil consumption and smoke from the exhaust
- Difficulty starting the engine, especially in cold weather

Diagnosis:
- Check cooling system for leaks, clogged radiator, or malfunctioning thermostat causing overheating
- Inspect carburetor settings and fuel delivery system for clogging or improper adjustment leading to poor fuel economy and power loss
- Examine ignition system components (spark plugs, distributor cap, rotor) for wear or fouling causing rough idling and stalling
- Look for worn piston rings or valve seals contributing to oil consumption and exhaust smoke
- Test battery condition and starter motor function to rule out starting issues

Fixes:
- Flush and clean the cooling system, replace thermostat and radiator hoses as needed to resolve overheating
- Rebuild or adjust the carburetor, replace fuel filters, and clean fuel lines to improve fuel delivery and engine performance
- Replace spark plugs, ignition wires, and distributor components to restore smooth idling and prevent stalling
- Perform engine overhaul or replace worn piston rings and valve seals to reduce oil consumption and smoke
- Service or replace battery and starter motor to ensure reliable engine starting

Prevention:
- Regularly check and maintain coolant levels and replace coolant according to schedule to avoid overheating
- Keep the carburetor and fuel system clean, and use quality fuel to prevent clogging and maintain efficiency
- Conduct periodic ignition system inspections and replace worn parts before failure
- Change engine oil and oil filter at recommended intervals to protect engine internals
- Store the vehicle properly in cold climates and use appropriate starting aids if necessary to prevent starting difficulties
