Is there a DIY method to check whether your Changan Karvaan fuel cap is functioning properly in Pakistan?

Yes, Pakistani drivers can use a simple twist-and-click test. If the cap doesn’t lock properly o r clicks loosely, it’s likely time to replace it. However, awareness of this check is still low among new drivers.

Yes, there is a simple DIY method to check if your Changan Karvaan fuel cap is functioning properly—especially useful for drivers in Pakistan:
🔧 Twist-and-Click Test

Open the fuel cap and then tighten it until you hear clicks.

A properly working cap will click firmly 2–3 times.

If the cap:

Doesn’t click at all

Clicks too loosely

o r feels wobbly o r cracked

👉 It likely means the seal is worn out, and the cap needs replacement.
