XC90 2.5T AWD L5-2.5L Turbo VIN 59 B5254T2 (2003)
This adjustment is carried out on a cold engine. A suitable temperature is approximately 20°C/68°F.
At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
The illustration shows the position of the indicator when aligning the timing belt tensioner at different temperatures.
Carefully turn the crankshaft clockwise until the timing belt is in the tensioned position (tensioned between the intake cam, idler pulley and crankshaft).
Hold the belt tensioner center screw secure. Turn the belt tensioner eccentric counter-clockwise until the tensioner indicator passes the marked position.
Turn the eccentric back until the indicator reaches the marked position in the center of the window.
Hold the eccentric secure and tighten the center screw. Tighten to 20 Nm. Ensure that the indicator is in the correct position.
