Key Features and Technical Specifications
The Carquest Premium Oil Filter 85372 is not just a simple canister; it is a precisely engineered component built for performance and protection. Its design incorporates several critical features that contribute to its effectiveness.
-
High-Capacity Filter Media: The filter contains a generous amount of synthetic blend media that is designed to trap and hold a large quantity of contaminants, dirt, and metal particles from the engine oil. This high dirt-holding capacity is essential for maintaining oil cleanliness throughout the entire oil change interval, especially in demanding driving conditions.
-
Anti-Drainback Valve: This is a crucial component made of a durable silicone material. Its purpose is to prevent oil from draining out of the filter when the engine is turned off. This ensures that oil pressure is built up almost instantly upon startup, providing critical lubrication to engine components within the first few seconds of operation, thereby reducing engine wear.
-
Bypass Valve: Also known as a relief valve, this internal safety feature protects your engine in case the filter becomes clogged. If the filter media is restricted, increasing oil pressure, the bypass valve opens to allow oil to continue circulating through the engine. While this unfiltered oil is not ideal, it is far better than having no oil flow at all, which would cause catastrophic engine failure.
-
Durable Canister and Gasket: The outer steel canister is constructed to withstand high internal oil pressure and resist corrosion. The gasket, which creates the seal between the filter and the engine block, is made of a high-quality rubber compound that remains pliable across a wide temperature range, preventing leaks.
-
Efficiency Rating: Premium filters like the 85372 are designed to achieve high filtration efficiency, often capturing a very high percentage of harmful particles as small as 20 microns. This level of filtration is vital for protecting sensitive engine components like variable valve timing (VVT) systems and turbochargers.
Step-by-Step Installation Guide
Installing an oil filter is a fundamental part of an oil change. For vehicles compatible with the 85372 filter, the process is generally straightforward. Always prioritize safety.
-
Gather Materials and Prepare: You will need the Carquest Premium Oil Filter 85372, the correct amount and type of new engine oil, a new drain plug gasket (if applicable), a wrench for the drain plug, an oil filter wrench, a drain pan, gloves, and safety glasses. Ensure the engine is cool or warm, but not hot enough to cause burns. Park on a level surface and engage the parking brake.
-
Drain the Old Oil: Locate the engine oil drain plug underneath the vehicle. Place the drain pan directly beneath it. Using the appropriate wrench, carefully loosen the drain plug. Once loose, unscrew it by hand, being prepared for hot oil to flow. Push the drain plug away quickly and allow the oil to drain completely.
-
Remove the Old Oil Filter: Locate the old oil filter. It will be a cylindrical metal canister screwed onto the engine block. Place the drain pan underneath it, as it will contain residual oil. Use an oil filter wrench to loosen the filter. Turn it counterclockwise. Once loose, you can unscrew it by hand. Carefully remove it and empty any remaining oil into the drain pan. Wipe the filter mounting surface on the engine block clean with a rag.
-
Prepare and Install the New Filter: Take your new Carquest Premium Oil Filter 85372. Dip your finger in clean new oil and lightly lubricate the rubber gasket on the top of the filter. This ensures a proper seal and prevents the gasket from sticking or tearing during the next removal. Do not pre-fill the filter with oil for this type of side-mounted filter, as it will simply spill out.
-
Screw on the New Filter: Carefully screw the new filter onto the engine mount by hand. Turn it clockwise until the gasket makes contact with the engine surface. Then, tighten it an additional three-quarters of a turn by hand. Avoid using a wrench to tighten the filter, as over-tightening can damage the gasket and make future removal extremely difficult.
-
Reinstall the Drain Plug and Add New Oil: Reinstall the drain plug with a new gasket if needed, tightening it to the manufacturer's specified torque. Lower the vehicle. Using a funnel, pour the recommended amount and type of new oil into the engine's oil fill cap. Replace the oil cap.
-
Check for Leaks and Oil Level: Start the engine and let it run for about a minute. Check around the oil filter and drain plug for any signs of leaks. Turn off the engine, wait a minute for the oil to settle, and then check the oil level with the dipstick. Add more oil if necessary to bring it to the full mark. Dispose of the old oil and filter responsibly at an auto parts store or recycling center.
Benefits of Using a Premium Oil Filter Like the 85372
Choosing a Carquest Premium filter over a basic economy filter provides tangible benefits for your vehicle's engine health and your long-term ownership costs.
-
Enhanced Engine Protection: The superior filtration media captures more and smaller contaminants. Cleaner oil means reduced wear on critical components like piston rings, cylinder walls, bearings, and camshafts. This directly contributes to extended engine life.
-
Improved Engine Performance: Clean oil flows better and lubricates more effectively. This can lead to smoother engine operation, quieter performance, and even marginally better fuel efficiency.
-
Support for Extended Oil Change Intervals: While you should always follow your vehicle manufacturer's recommended oil change intervals, using a high-quality filter provides an extra margin of safety. The filter's high dirt-holding capacity means it will remain effective for the full duration of a standard oil change cycle.
-
Protection for Modern Engine Technologies: Many modern engines feature complex systems like variable valve timing (VVT) that rely on clean oil at precise pressures. A clogged or inefficient filter can disrupt oil pressure, leading to poor performance, check engine lights, and expensive repairs. The reliable performance of the 85372 filter helps safeguard these systems.
-
Peace of Mind: Knowing that you have installed a filter designed with robust components like a silicone anti-drainback valve and a reliable bypass valve provides confidence that your engine is well-protected, especially during cold starts.
Troubleshooting Common Oil Filter Issues
Even with a high-quality filter, issues can sometimes arise. Understanding them helps in diagnosis.
-
Oil Leak from the Filter Base: This is almost always caused by an improperly installed gasket. The cause could be a damaged gasket, a double-gasket (if the old gasket stuck to the engine), or an under-tightened filter. The solution is to remove the filter, inspect and clean the mating surface, and reinstall a new filter correctly.
-
Low Oil Pressure After Change: If the oil pressure light remains on or the gauge reads low after an oil change, it could indicate a problem with the filter's anti-drainback valve. A faulty valve would allow oil to drain back, causing a momentary delay in pressure buildup. While rare with new premium filters, it is a possibility. Verify the correct filter was used.
-
Engine Making Noise on Startup: A ticking or knocking noise that lasts for a second or two after startup can be a sign of oil draining out of the filter due to a failing anti-drainback valve. This leads to a brief period of inadequate lubrication. Using a quality filter with a robust silicone valve, like the one in the 85372, minimizes this risk.
