Engine

4.0L Inline-6

• Oil Leaks
  • Description/Symptoms: Oil leaks are common around the valve cover gasket, oil pan gasket, and rear main seal. Symptoms include visible oil leaks, burning oil smell, and low oil levels.
  • Solution: Replace the affected gasket or seal.
  • Estimated Cost to Fix: $50 - $200+ depending on the location of the leak and the shop’s labor rates.
  • Recalls: None Found
• Overheating
  • Description/Symptoms: Overheating can be caused by a failing radiator, thermostat, water pump, or clogged cooling system. Symptoms include high temperature gauge readings, steam from the engine, and coolant leaks.
  • Solution: Diagnose the cooling system and replace the faulty component(s). Flushing the cooling system is recommended.
  • Estimated Cost to Fix: $100 - $500+ depending on the specific issue.
