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