Dodge Intrepid 1998-2004 2.7L Engine Specifications

The 2.7L engine was specifically designed for the 1998-2004 Dodge Intrepid and is not directly compatible with other Dodge models without significant modifications. It features a V6 configuration, aluminum block, and SOHC design. Always verify compatibility with your vehicle's VIN and consult a professional before attempting cross-model installations.

The 2.7L engine requires regular oil changes every 3,000-5,000 miles using 5W-30 synthetic oil. Inspect the timing belt every 60,000 miles and replace it if worn. Regularly check coolant levels and replace the thermostat every 50,000 miles. Ensure the PCV valve and air filter are inspected and replaced as needed to maintain optimal performance.

To replace the 2.7L engine, disconnect the battery, drain fluids, and remove the engine mounts and accessories. Use an engine hoist to lift the old engine out. Install the new engine by reversing the removal process, ensuring all connections are secure. Torque bolts to manufacturer specifications and refill fluids. Start the engine and check for leaks or irregularities.

Common issues include oil sludge buildup and timing belt failure. For oil sludge, perform a thorough engine flush and replace the oil filter. For timing belt issues, inspect for wear and replace if necessary. Check for coolant leaks, which may indicate a failing water pump or gasket. Use an OBD-II scanner to diagnose error codes for further troubleshooting.

To optimize performance, use high-quality synthetic oil and replace the air filter regularly. Upgrade to a high-flow exhaust system and ensure the throttle body is clean. Consider installing a performance chip for improved fuel mapping. Regularly inspect and maintain the cooling system to prevent overheating, which can degrade engine performance over time.
