I had issues with the locks pins kept jumping out so I had to be really really careful. I ended up lifting the rocker on the valve that was down and it was really really easy to do. Take the rocker cover off and slacken off the rocker arm so the pushrod isn't forced against the cam lob then to all stays where you put it. I also put a spanner around the flat on the tensor and turned it to take the tension off the belt. If you put the end of the spanner on the end of the trolley jack you can lift the end to get the tension off and still have 2 hands for the belt. Then the job was easy!Hope that helps...
