Belt tensioning check
Use the DENSO tool to measure the belt tension, carefully place the denso on the belt tooth as shown in figure 36.
The belt tension should be between 25 and 28 Nm, see Fig. 37.
If this is not the case loosen the idler, let it slide downwards and tighten it again to the rated torque, then re-check the tension.
When removing the timing belt you must replace it even though its scheduled life spar is not over.
