Step-by-Step: The Ultimate Car Oil Pump Change Guide for DIYers
Ready to get your hands dirty? This comprehensive car oil pump change guide will walk you through the process. Remember, patience and attention to detail are your best friends here.
1. Prepare the Vehicle
Start by properly jacking up your vehicle safely and securing it on jack stands. Ensure you have ample space to work underneath. Disconnect the negative terminal of the battery.
2. Drain the Engine Oil
Place your oil drain pan directly beneath the oil pan drain plug. Use the appropriate wrench to remove the plug and allow all the old engine oil to drain completely. Once drained, reinstall the drain plug, but don’t over-tighten it.
3. Remove the Oil Pan
This is often the most labor-intensive part, as it may involve removing other components first. You might need to:
- Remove exhaust pipes or crossmembers that obstruct access.
- Disconnect steering linkages or sway bars on some models.
Once clear, carefully unbolt the oil pan. There will be many small bolts around the perimeter. Gently pry the pan loose, being careful not to damage the engine block’s sealing surface. Be prepared for residual oil to spill out.
4. Access and Remove the Old Oil Pump
With the oil pan removed, you’ll see the oil pump, typically located at the front or center of the engine block, often connected to the crankshaft or a camshaft.
- Locate the bolts securing the oil pump to the engine block.
- Remove the oil pump pickup tube, which is usually bolted to the pump and dips into the oil.
- Carefully unbolt and remove the old oil pump. Note its orientation for correct installation of the new one.
5. Clean and Prepare Surfaces
This step is critical for preventing leaks. Use a gasket scraper or razor blade to meticulously remove all traces of old gasket material from both the engine block’s mating surface and the oil pan’s flange. Clean both surfaces thoroughly with brake cleaner or a similar degreaser to ensure they are free of oil residue.
6. Install the New Oil Pump
Carefully position the new oil pump, ensuring it aligns correctly with the drive mechanism (e.g., crankshaft sprocket). Bolt it into place, tightening the bolts to the manufacturer’s specified torque using your torque wrench. Reattach the oil pump pickup tube, ensuring its screen is clean and undamaged.
7. Reinstall the Oil Pan
Apply a thin, even bead of RTV sealant (if required by your vehicle’s manufacturer) to the new oil pan gasket, or directly to the oil pan flange. Carefully position the new gasket on the oil pan, then align the oil pan with the engine block.
Start all the oil pan bolts by hand to prevent cross-threading, then progressively tighten them to the manufacturer’s torque specifications, often in a crisscross pattern for even pressure. This is a critical step for preventing future leaks.
8. Replace Oil Filter and Add New Oil
Install a new oil filter. Then, lower the vehicle slightly and add the recommended type and quantity of fresh engine oil. Use a funnel to prevent spills.
9. Initial Startup and Checks
Before starting the engine, reconnect the battery. Turn the key to the “ON” position (without starting) for a few seconds to allow the pump to prime. You might hear some faint gurgling. Then, start the engine and immediately check for the oil pressure warning light to turn off. If it stays on, shut off the engine immediately and recheck your work.
Let the engine run for a few minutes, carefully inspecting for any oil leaks around the oil pan or oil filter. Once satisfied, lower the vehicle completely and recheck the oil level, topping off if necessary.
