Parts for your 2013 Volkswagen Amarok-Oil cap

2013 Volkswagen Amarok Oil Cap — Purpose, Care, and When to Replace

The 2013 Volkswagen Amarok absolutely uses an oil filler cap. Volkswagen’s 2013 Amarok Owner’s Manual identifies the cap under the bonnet with the oil-can symbol on the cylinder-head/rocker cover. Volkswagen’s official parts catalogue (ETKA) and the erWin workshop manual for Amarok (Repair Group 17 – Engine lubrication) also show the oil filler cap with an integrated seal as part of standard servicing. So yes—this ute is designed to run with an oil cap fitted and properly sealed.

On the Amarok’s 2.0 TDI, the oil cap does three simple but critical jobs: it seals the top of the engine so oil doesn’t splash out, it keeps dust and moisture from getting into the crankcase, and it helps the engine’s ventilation system maintain the right pressure. If the cap’s missing, cracked, or not sealing, owners can end up with oily residue across the top of the engine, a whiff of hot oil under the bonnet, and contamination that shortens engine and turbo life.

As part of routine servicing, the oil cap deserves a quick once-over. Wipe away grime before removing it, so nothing falls into the engine while topping up. When refitting, tighten by hand until fully seated—no tool needed—so the seal sits evenly. The cap on these engines includes a rubber O-ring/seal that can harden with age or exposure to heat and crankcase vapours. If it looks flat, cracked, or shiny-hard, replace the cap (or seal, if serviceable) to prevent weeping.

Tell-tale signs it’s time for attention include light oil mist around the filler neck, cap that no longer “bites” or feels loose, a burnt-oil smell after driving, or minor oil spots collecting on nearby hoses and covers. These small warnings are far cheaper to sort than letting grit or water into the engine during an oil top-up on a worksite or track.

• Inspect the cap and seal at every oil change or 10,000–15,000 km service interval (follow VW’s schedule for your engine and conditions).
• Clean the cap threads and seating area with a lint-free cloth.
• Replace the cap if the seal is perished, the cap is warped, or it doesn’t lock down snugly.
• Always refit the cap before starting the engine after a top-up—running without it can spray oil and invite contamination.

Kept in good nick, the Amarok’s oil cap is a low-cost part that protects a very expensive engine. It’s a quick check that pays off every service.

Popular questions about 2013 Volkswagen Amarok oil caps

Where is the oil cap on a 2013 Amarok, and how do you open it?
It sits on top of the engine’s rocker cover and is marked with an oil-can symbol. Twist anti-clockwise by hand to remove. Wipe around it first so dirt doesn’t fall into the engine during a top-up, then refit and turn clockwise until it seats firmly.

What are the signs the Amarok’s oil cap needs replacing?
Look for oil dampness or staining around the filler neck, a cap that won’t seat snugly, a hardened or cracked O-ring, or a hot-oil smell after drives. Any of these indicates the seal isn’t doing its job and the cap should be renewed.

Is it safe to drive if the oil cap is missing or damaged?
No. Driving without a proper cap can spray oil under the bonnet, attract dust and water into the engine, and risk engine damage. If the cap is missing or broken, replace it before driving any further.
