If you own a Subaru vehicle, you know the importance of proper maintenance to ensure its longevity. One critical aspect of maintenance that is often overlooked is priming the oil system. Priming the oil system is a process that involves filling the oil pump completely with oil before starting the engine. In this article, we will go over the importance of priming the Subaru oil system, when to prime it, and provide step-by-step instructions on how to prime the oil system for optimal engine performance.
Why is it important to prime the oil system?
The oil system in your Subaru vehicle is responsible for lubricating the engine components and dissipating heat. Priming the oil system is important because it ensures that there is enough oil in the pump before the engine starts. Without enough oil, the engine components can wear out quickly, leading to catastrophic engine failure, and expensive repairs.
When should you prime the oil system?
You should prime the oil system in your Subaru vehicle when installing a new oil pump, after replacing the oil filter, or performing any repair that involves disconnecting the oil lines. However, it is always a good practice to prime your Subaru oil system before starting the engine after an oil change.
How to prime the oil system: Step-by-step guide
Here is a step-by-step guide on how to prime the Subaru oil system:
- First, ensure that the car is parked on a level surface and turn off the engine.
- Locate the oil filter and remove it using an oil filter wrench.
- Fill the new oil filter with oil to at least three-quarters full.
- Lubricate the rubber gasket on the new oil filter with some oil and replace the old filter with the new one.
- Remove the oil filler cap and pour in the recommended amount of oil into the engine.
- Slowly rotate the engine using the crankshaft pulley or a specialized tool to allow the oil to circulate through the engine.
- After a complete rotation, replace the oil filler cap and start the engine.
- Allow the engine to run for about five minutes, checking the oil pressure gauge or light to ensure that there are no issues.
- Turn off the engine, allow it to cool for a few minutes, and then check the oil level on the dipstick. Add oil as necessary.
What tools and materials are required to prime the oil system?
To prime the Subaru oil system, you will need the following tools and materials:
- New oil filter
- Oil filter wrench
- Crankshaft pulley or specialized tool
Common mistakes to avoid when priming the oil system
Here are some common mistakes to avoid when priming the oil system to prevent damage to your vehicle:
- Not filling the oil filter with oil before installation.
- Using the wrong oil type or viscosity for your engine.
- Overfilling the engine with oil, which can cause serious damage.
Tips on maintaining your Subaru oil system
Maintaining the oil system in your Subaru vehicle is critical to ensure its longevity. Here are some tips on how to keep your oil system in good condition:
- Change the oil and oil filter at the recommended intervals.
- Use the recommended type and grade of oil for your Subaru engine.
- Check the oil level regularly and top up when necessary.
- Check for leaks or other signs of damage in the oil system.
Q: How often do I need to prime my Subaru oil system?
A: You only need to prime your Subaru oil system when installing a new oil pump, after replacing the oil filter, or performing any repair that involves disconnecting the oil lines.
Q: Why is my oil pressure gauge fluctuating after priming the oil system?
A: If your oil pressure gauge is fluctuating after priming the oil system, it could be due to a faulty oil pressure sensor or a clogged oil filter.
Q: Can I overfill my engine with oil while priming the oil system?
A: Yes, overfilling your engine with oil can cause serious engine damage, so be sure to follow the manufacturer’s recommendation on the correct oil level.
In conclusion, priming the oil system in your Subaru vehicle is an essential part of maintaining its longevity. By following the step-by-step guide, using the right tools and materials, and avoiding common mistakes, you can ensure optimal engine performance and avoid costly repairs. Keep your oil system in good condition by performing regular maintenance checks and always using the recommended type and grade of oil.
