How to fit cam belt to renault megane 1.5 dynamique diesel 2004

Not difficult with the right equipment ,firstly you will need a special tool to lock the crankshaft in place ,then another special tool than aligns the tdc this goes through the cylinder block at the front right hand side by taking a bolt out in the block thats just in front of the bell housing .The special tools cost an arm and a leg trust me and then the pulley bolt has to be pulled up to 130lbs ,the bottom pulley does not have a keyway so without the right tools its very easy to let the engine turn and clout the valves which breaks the camshaft bearing caps with relative ease .the kit you need can be bought and its kit number AST4390 plus the locking pieces for the flywheel .This is not a weekend mechanic type job ,yes its easy with the right tools but even myself will slacken tensioner and remove the cam before i start so valves cannot catch when i turn engine over on starter with a big bar on the pulley nut ,then change the belt then with assistant holding a snap on heel bar in the flywheel ring gear whilst i hammer the bottom pulley bolt with the air wrench ,then use the 80cm knuckle bar and have a good grunch to make sure its really tight or it WILL TURN and the valves hit and break and imbed themselves in the pistons and smash the cam bearing caps .This is not a job for the faint hearted ,their is a timing mark on the flywheel looking from the top through a elongated hole and TDC is a longer tooth ,the inspection slot is about 3cms down from the crank sensor
