Parts for your 2014 Nissan Pathfinder-Oil cap

2014 Nissan Pathfinder oil cap – what it does and how to look after it

The 2014 Nissan Pathfinder (R52, VQ35DE 3.5L V6) is fitted with an engine oil filler cap. This is confirmed by Nissan’s Owner’s Manual for 2014 Pathfinder (Maintenance and do‑it‑yourself section, engine compartment check locations), the Nissan Electronic Service Manual lubrication section (oil refilling procedures specify removing and refitting the oil filler cap), and Nissan’s parts catalog, which lists a cap‑oil filler for this model and engine. So yes—an oil cap is relevant and used on this vehicle.

The oil cap seals the top of the engine’s oil filler neck under the bonnet. Its job is simple but critical: it keeps dust and moisture out, prevents oil mist from escaping, and helps the crankcase ventilation system maintain the right flow. A sound cap with a good seal helps keep the engine bay tidy, prevents that burnt‑oil whiff, and protects the engine from contamination that can shorten oil and filter life.

During servicing of a 2014 Pathfinder, the oil cap should be removed for refilling and then refitted hand‑tight—snug until the seal seats, without reefing on it. Over‑tightening can deform the gasket or crack the cap, under‑tightening risks leaks. A quick wipe of the cap and filler neck before refitting keeps grit out of the engine. It’s good practice to check the cap’s rubber seal or O‑ring every service (around 10,000–15,000 km or as per the schedule). Replace the cap or seal if it’s hard, split, swollen, or missing.

If the cap is damaged, misplaced, or stuck, don’t drive far without sorting it. Running without a cap can throw oil around the engine bay and drag dust into the engine. If it’s stuck, a warm engine (not hot), a rubber glove for grip, or a strap wrench usually does the trick—avoid pliers that can crack the plastic. When replacing, choose a genuine or quality aftermarket cap that matches the VQ35DE filler neck, the correct cap will sit flat, seal evenly, and usually carries the recommended oil grade marking. If in doubt, confirm by VIN or engine code rather than guessing thread type.

• Replace the oil cap if you notice oil weeping around the filler, a perished seal, fuel or oil smells under the bonnet, obvious cracking, or if the cap won’t tighten cleanly.
• After any service, run the engine and check around the cap for leaks—wipe, then recheck.

Popular questions

Where is the oil cap on a 2014 Nissan Pathfinder?
It sits on the top of the engine’s front rocker cover under the bonnet, clearly marked “Engine Oil”. Look for a black plastic cap near the centre‑front area of the V6. It twists off for refilling and twists back on until seated.

Can the Pathfinder be driven without the oil cap?
Best not. Without the cap, oil can spatter out and dust can be drawn into the engine, risking accelerated wear. If the cap is missing, shut it down and fit the correct cap. A temporary cover is only to move the vehicle a very short distance for repair—get a proper cap on promptly.

How do you know the oil cap needs replacing?
Common signs are a cracked cap, a flattened or brittle O‑ring, oil mist around the filler area, or a cap that won’t seat smoothly. If the seal’s gone hard or swollen, replace the cap or seal at the next service to keep things tidy and airtight.
