Vehicles using D15B2 engine list:

Engine D15B2 commonly faces issues like worn timing belts, valve cover gasket leaks, and idle roughness due to dirty IAC valves. For diagnosis, check for oil leaks around the valve cover and listen for unusual engine noises indicating timing belt wear. Prevent problems by replacing the timing belt every 60,000-90,000 km and regularly cleaning the idle air control valve. If rough idling occurs, inspect and clean or replace the IAC valve. Valve cover gasket leaks require gasket replacement to prevent oil loss and contamination. Regular oil changes and using quality fuel help maintain engine longevity and performance.
