My Opel AStra 160IE F. It alway worn the fan belt what could be the problem
First make sure it is the correct belt for that engine. Sometimes the really cheap belts are often not quite the correct size so they wear out faster. If it has covers over the belts are they fitted correctly? Are you having any other issues with the car? A battery not charging or an over heating problem? These can give clues to possible reasons for the belt wear. Where on the belt are the wear marks showing? If it is on the smooth back side of the belt there is probably something rubbing on it. Look to see if there is something else in the engine bay that is sticking out and touching where it shouldn't.
If it is on the ribbed, working side of the belt it could be a pulley wheel causing the issue. The tensioner could be sticking or failing so it isn't adjusting for engine speed changes. It could also be one of the pulleys it runs around 'dragging'.
With the engine OFF remove the belt and check the tensioner moves freely against the spring inside it. Turn all the smaller pulley wheels the belt runs around by hand. They should turn smoothly, freely and quietly. If they feel 'gritty' or seem noisy that could be where the issue is.

1989 Kadett 1.3l. What are the camshaft torque settings?
The camshaft and it's housing is retained by the cylinder head bolts - if you have removed the camshaft housing the cylinder head gasket must also be replaced and the latest torque figures are usually supplied with a replacement gasket.
The male and female threads must be cleaned and lubricated and any stretched or corroded bolts replaced. The washers too and under the bolt heads must be lubricated. The bolts are tightened starting with the centre pair and working outwards in a spiral pattern.The bolts are tightened first to an initial torque of 18 lb-ft and then by 60 degrees + 60 + 30 degrees and then after thoroughly warming up the engine and at least 6 hours cooling time, by a further 30 - 50 degrees depending on "feel", but you should verify these figures before proceeding...
The tappets are self adjusting hydraulic that will fully extend when the cam housing is removed. If the advice in the repair manual is followed, restarting the engine after rebuild will be difficult so it is best to empty them of oil before refitting by gently squeezing each in a vice several times with the oil hole downmost.
For future reference, there is a service tool designed to allow camshaft removal without removing the cylinder head bolts.
Kadett Euro 200is 8v. What are head torque settings?
Vauxhall/Opel's 8 valve 2 litre ohc engine, working from memory - the initial torque starting from the middle pair of bolts and working outwards in a spiral pattern is 18 lbft.
This is followed by further tightening in stages of 60 degrees + 60 + 60.
After thoroughly warming up and allowing at least 6 hours cooling time the bolts are tightened a further 30 - 60 degrees, depending on "feel".
Stretched or corroded bolts should be replaced, all male and female threads should be thoroughly cleaned and lubricated as should the washers and under the bolt heads. Starting after rebuild is easier if the hydraulic tappets are emptied of oil prior to refitting.
The current tightening specs are usually provided with the replacement gasket.
Opel corsa bakkie utility 2008 1.4 frequence of head torque
It somewhat depends on which engine version is fitted but the Vauxhall/Opel ohc engines need the initial angular torquing of the cylinder head bolts and after a warm up and cool down cycle a further small tighten. You will of course have to obtain the exact values from the applicable engine data though this is usually provided with a replacement head gasket.
After thoroughly cleaning of the parts including the female and male head bolt threads. Fit the new gasket and the head, etc. Preferably using new bolts but certainly replacing any corroded or stretched bolts, lubricate the threads and washers and fit the bolts and using a suitable torque wrench tighten in an outward spiral pattern to the initial figure (usually around 18 lb-ft).
Using the same outward spiral pattern the bolts are then further tightened in four stages that is something like 60 degrees + 60 + 30 and then after thoroughly warming up the engine and allowing it to cool for at least 6 hours, tighten a further 30 degrees.
No further tightening is required...
