I'm not sure if this applies to all cars or just the Mazda 3, but I've started to hear a clunky sound from the 3, even at idle it's just weird. Is there anything I could check before giving up and sending it to a proper mechanic?

Should mention it's practically brand new. 08 Model, and it's done 19,xxx kms. Getting it's 20k service soon too.

Does it only happen at a certain RPM?

If so could be the belt tensioner.

Here's the precedure to fix this problem,Thank U John! (Ecu-man)

Hi Dude

this is Honda's solution

1. Connect the PGM tester to the vehicle

2. Start the Engine and allow it to reach operating temperature ( Radiator Fans should come on twice )

3. Remove the upper timing belt cover

4. monitor the engine temperature. When the temp decreases to 58degC, rotate the crankshaft five or six turns counter clockwise.

5. Set No. 1 piston at TDC

6.When the engine temp decreaces to 55degC, loosen the timming belt adjusting bolt 180deg. Allow the tention of the timing belt to automaticlly reset the tentioner position.

7. Tighten the adjusting bolt.

8. After adjustment, retorque the crankshaft pulley bolt to 181 Nm

9. On compleating the procedure, start then engine and allow it to reach operating temperature. Confirm the noise has been eliminated. Should the noise still be exhibited the above procedure in its entirety is required to be repeated.


I will assume you wont have access to the PGM tester or a HDS, so you can monitor the ECT voltage to determine the engine Temp

the below is from temp v voltage when looking at the HDS.



ECT voltage at 58 deg 1.44v

ECT Voltage at 55 deg 1.55v


ECT is Engine Coolant Temp

and HDS is Honda Diagnostic System.
