Toyota Estima Engine Knocking Noise
🚗 Toyota Estima Engine Making “Kok Kok” Noise? It Could Be the Balance Shaft!
Do you hear a metallic knocking sound (“kok kok”) when starting your Toyota Estima, especially when the engine is cold?
⚠️ Many drivers think it's normal — but this could be an early sign of a worn or loose balance shaft.
🔍 Common Symptoms:
-
Knocking sound on cold start
-
Sound disappears after 2–5 seconds
-
Slight engine vibration at idle
-
Increased fuel consumption or poor performance
🔧 What Causes This?
The balance shaft is designed to reduce engine vibration.
Over time, its bearings may wear out, or the shaft may become loose.
This causes metal-to-metal contact, especially when the engine is cold and the parts haven't expanded fully.
⚠️ What Happens If You Ignore It?
-
Knocking noise will get louder over time
-
Engine vibration may become worse
-
Could lead to internal engine damage, requiring costly repairs or overhaul
✅ What You Should Do:
✔ Get your Estima checked by a specialist workshop familiar with Toyota MPV engines
✔ Early detection and repair can save you time and money
✔ Don’t wait for the noise to get worse
