Parts for your 2016 Subaru Exiga-Fuel cap

2016 Subaru Exiga fuel-cap — purpose, care and when to replace

Based on technical sources including the Subaru Exiga/Crossover 7 Owner’s Manual (2015–2017, “Fuel filler lid and cap”) and the Subaru Service Manual sections for Fuel Tank and EVAP (Evaporative Emission Control), the 2016 Subaru Exiga is fitted with a conventional, screw‑type sealing fuel cap. The EVAP system on this model relies on a correctly sealing cap to prevent petrol vapour leaks and to satisfy OBD monitoring, so a fuel-cap is absolutely relevant for this vehicle.

The Exiga’s fuel-cap does more than just close the filler neck. It seals the tank to keep petrol vapours in check, supports the EVAP system so the car passes emissions self‑tests, and helps maintain proper tank pressure so refuelling and engine running stay drama‑free. When the cap doesn’t seal, owners may notice a petrol odour, a faint hiss that never quite goes away, or the Check Engine Light after a fill‑up.

As part of regular servicing in Australia and New Zealand conditions, the fuel-cap on a 2016 Subaru Exiga deserves a quick once‑over. Wipe dust from the filler neck, check the rubber seal for nicks or flattening, and make sure the ratchet action tightens until it clicks. Subaru literature for this platform specifies tightening the cap until it clicks, if it won’t click or it free‑spins without bite, it’s time for a replacement.

• Common signs it needs attention:
  • Fuel smell around the left rear quarter after parking
  • Check Engine Light with small/large EVAP leak codes after refuelling
  • Cap won’t “click” or the tether is broken

Replacing the Exiga fuel-cap is straightforward: use a genuine Subaru cap or a quality OEM‑equivalent that’s EVAP‑rated for this model. Fit the new cap, turn it clockwise until the clicks are heard, then drive a few trips so the EVAP monitor can recheck itself. During services (roughly every 10,000–15,000 km), a quick clean and seal check helps prevent nuisance warnings and fuel vapour loss.

For owners who tour long distances, carrying a spare cap isn’t a bad shout—it’s inexpensive insurance against an avoidable warning light or fuel odour on the road.

• Handy tips:
  • Keep grit out of the filler area before opening the cap
  • If the rubber O‑ring looks hard or cracked, replace the cap
  • Always tighten until it clicks, don’t over‑muscle it

Popular questions about 2016 Subaru Exiga fuel-caps

What type of fuel-cap does the 2016 Subaru Exiga use?
The 2016 Exiga uses a screw‑type, ratcheting EVAP‑sealing petrol cap with a rubber seal and a tether. It’s designed to “click” when tight, confirming the correct seal for the EVAP system.

How often should the fuel-cap be replaced?
There’s no fixed interval, but inspecting it at every service is smart. Replace it if the seal is damaged, the cap won’t click, the tether snaps, or persistent EVAP leak faults appear after refuelling.

Why did the Check Engine Light appear after refuelling?
Often it’s a loose or worn cap allowing vapour to escape. Refit the cap until it clicks, clear any dust from the neck, and drive a few trips. If the light stays on, the seal may be done or another EVAP component needs a look.
