I marked the cam pulleys and rear covers before the belt came off for reference, but didnt mark the belt? The cam sprocket bolts have not been loosened yet either

I then refitted the sprockets with the bolts hand tight, laced the belt with locking tools in place and set the tensioner pulley according to INA's instructions. Finally tighten the sprocket bolts to the specified torque before removing the locking tools. But there really is no advantage in loosening the sprocket bolts as the toothed wheel will move about 15˚ anyway and loosening them won't increase this. Simon

The tools are there to set the cam positions relative to the crank. If it’s not moved since the engine was built (which I appreciate isn’t an impossibility but highly unlikely) then it will still be timed. If anything had slipped you’d know about it by the way the engine is running and then of course you’d need the timing tools.

If you do have the tools and you do slacken the pulleys , then when you fit and tension the belt the pulleys can move to fit the belt teeth perfectly and you get a very uniform tension on the belt with the camshafts staying exactly where they were
One of the bits of the job I find satisfying , but then folk are always telling me to get a life .....

Thanks for the replies everybody, have got to get my finger out and get the job done now.
Have been self isolating after being in close contact with a positive testing person, starting to feel a bit rough myself(symptoms). Have got a replacement aux belt coming sometime today so need to be ready for it, i.e. belt on/ front plate on/alternator/pas pump. Take camshaft end caps off for locking tools to fit, hope the marks i made on pulleys and rear covers line up and rear pulleys line up again after fitting tools and route belt/ release tensioner, front plate then ancillaries ready for aux belt. Need to get another hours sleep first heads banging

Just so that you're not taken by surprise, with the front locking tools fitted you'll more than likely find that the notches on the rear sprockets don't quite line up. Many people have found this (including myself). It appears to be a quirk of the engine design which has never been satisfactorily explained. Just keep calm and carry on! After you've fitted and tensioned the front belt you will need to remove the flywheel/drive plate locking pin and turn the engine ever so slightly so that the rear sprocket notches do align in order to fit the removal tool. I wouldn't return to this job until you're feeling 100 per cent though Steve. Wishing you well. Simon

Just to update this thread, Steve has let me know that he has successfully fitted his new front timing belt.
