Cooling System Issues: Low coolant levels, radiator blockages, or faulty thermostats.
Water Pump Failures: Leaking or damaged water pump.
Fan Problems: Non-functional cooling fan or fan clutch.
Head Gasket Failure: Leaking head gasket causing coolant loss and overheating.
Check Coolant Levels: Ensure the coolant reservoir is full and check for leaks.

Black Smoke: Unburned fuel due to faulty injectors, turbocharger issues, or dirty air filters.
Blue Smoke: Oil burning due to worn piston rings, valve seals, or turbocharger seals.
White Smoke: Coolant entering the combustion chamber due to a blown head gasket or cracked cylinder head.
Identify Smoke Color: Determine if the smoke is black, blue, or white to diagnose the issue.
Check Fuel System: Inspect injectors, fuel filters, and pressure regulators for black smoke.
Examine Turbocharger: Look for oil leaks or damage that could cause blue smoke.
Inspect Engine Internals: Check piston rings and valve seals for wear.
