Timing Belt Tensioner: Adjustments

ADJUSTING THE MECHANICAL BELT TENSIONER

As the illustrations in the information are used for different model years and/or models, certain variations may occur. However, the essential information in the illustrations is always correct.





Adjusting The Camshaft Belt Tensioner And Camshaft Belt
- Install timing belt.
- Ensure that belt is tight between crankshaft and intake pulley, if not reinstall.
- Tighten the center screw to 5 Nm (4 ft/lb).
- Holding the center screw stationary, turn the eccentric (A) with a 6 mm (15/64") Allen key counter-clockwise until the tensioner indicator passes the right side of the adjustment window (B).
- Turn the eccentric (A) clockwise until the indicator (C) reaches the correct position based on the temperature of the engine (see illustration below).
- Hold the eccentric secure and tighten the center screw to 20 Nm (15 lb.ft).


Note: When setting the final adjustment the needle (C) must enter the adjustment window (B) from the right. If the needle exits the window to the left, it must be readjusted past the window so that it enters from the right.

- Press on the timing belt and verify that the indicator moves in response to the pressure

Note: If the bolts holding either cam wheel had been loosened, tighten them at this time to 20 Nm (15 ft lb).

- Press the camshaft belt and check that the camshaft belt tensioner needle moves freely.

The position of the needle at different temperatures
This adjustment is to be made with a cold engine.
A suitable temperature is approximately 20°C (168°F).
At a higher temperature, for example with a warm engine or a higher ambient temperature, the needle is further to the right.




The position of the indicator when aligning the camshaft belt tensioner at different temperatures is shown in the illustration.
