I used it on a D17A2 motor that was in a 2002 Honda Civic ex, it fit very well but falls out easy if you don't have it wedged it in just right against something else(control arm, ground, or axle) it will fall out or slip out. If this happens in the middle of trying to take the crank bolt out you will break your hands unless your superman but then you will have to repave your driveway. That is why I say this is a 2 person job one to pull the breaker bar and one to keep it in the crank. If the fit had less play it would get 5 stars but this is a great tool!
