How to Change an Oil Pan Gasket on a Honda
- 1). Drive the Honda onto a set of ramps to lift the front of the vehicle off the ground. If you do not have ramps, jack the Honda up with a floor jack and use jack stands to secure the vehicle off the ground.
- 2). Remove the aluminum or plastic skid plate that covers the lower A-arms and oil pan. Over the years, Honda has used aluminum and plastic skid plates on many of their compact models. However, on mid-sized to larger SUV models, they do not use them. If your Honda does not have a skid plate, skip this step. To remove the skid plate, locate and remove all of the Torx-end screws (star bolt) with a Torx bit.
- 3). Place a drain pan under the oil pan and drain the engine oil into the pan. To do so, remove the oil drain plug with a boxed wrench. With the oil drained, reinsert the drain plug to avoid losing it.
- 4). Remove all of the bolts that secure the oil pan to the engine block with a boxed wrench or a ratchet and socket set. The amount of screws varies on the model of engine. It ranges from 18 to 24 bolts.
- 5). Wedge a flat-head screwdriver between the mating surfaces of the oil pan and the engine block to separate the seal between the two. Continue to wedge the tip of the screwdriver around the oil pan until it drops loose from the engine.
- 6). Remove all of the old gasket and gasket sealer from the mating surfaces of the engine block and the oil pan. Wipe both surfaces clean with mineral spirits.
- 7). Place a bead of RTV gasket sealer on the mating surface of the oil pan. Allow the sealer to cure for 20 minutes before moving on.
- 8). Place the oil pan gasket on top of the RTV gasket sealer and lightly press it into the sealer.
- 9). Place another bead of RTV gasket sealer on top of the oil gasket and allow another 20 minutes for the gasket sealer to cure.
Gently push the oil pan against the mating surface of the engine block and place the bolts in with your fingers. Thumb-tighten the bolts in an alternating manner, left to right.
