  Q: How to remove and install the timing chain and sprockets in 2.0L/2.2L four cylinder overhead valve engine for a Chevrolet Beretta?

  A: Before doing anything, it is paramount to put off the lockout feature if you have a Delco Loc II audio system fitted in your car. Undo the Crankshaft Pulley. Remove the chain cover and then the timing chain itself from your engine. You need to check for sprocket teeth wear as well as excessive slack in the chain before separating them from each other; also inspect the condition of the timing chain tensioner. Replacing worn-out sprockets would be necessary when any sign of wear is detected on either or both of them. Engine performance may become unreliable, fuel efficiency decrease, and power loss can occur due to an old timing chain that needs to be replaced. As such, when one component fails you should go ahead and replace others related including tensioners. In such cases where replacement of chains or sprockets is needed, carry out these steps mentioned nextly: Insert crankshaft pulley hub temporarily and attach its bolt; turn crankshaft until marks coincide on camshaft sprockets together with those on tabs; compress spring against tensioner while putting a suitable sized drill bit into its hole until it does not go back anymore; use two bolts in front part of crankshaft balancer hub for preventing turning engine when removing camshaft bolt by means of a prybar (i.e., an unusually shaped piece without sharp ends which serves for levering objects); remove camshaft sprocket by gently prying outside with screwdrivers at two different points thus allowing their action upon outer rim so that this can easily come away followed by withdrawal itself fully along with accompanying gear assembly assembled tandem with other parts making up entire unit (comprising main gear); first engage toothed wheel then ensure link aligns properly within it before fitting onto shaft again before finally securing threaded fastener through frictional engagement only so as not allow loosening thereof during operation afterwards; lastly push against spring-loaded holder thereby releasing pressure from chain which in turn causes it to snap into place; lubricate motor with fresh oiling substance. After two full wheel turns, ensure timing marks coincide once again then put on new gasket and tighten bolts fixing the cover over gear train opening. Mount pan for oil content. All other steps are considered as reverse of what was initially carried out during removal procedure.

  Q: How to remove and reinstall the timing chain and Sprocket in V6 engine for Chevrolet Beretta?

  A: Upon covering a distance of more than eighty thousand miles, visible damage inflicted on the chain, or when total free play exceeds one inch midpoint between sprockets there should be replacement of the timing chain. It is important to replace a worn-out timing chain so that it doesn't lead to irregular engine functioning, loss of power and low fuel efficiency. Timing errors can happen if chains become loose. In some cases when the chain jumps time or breaks down, the consequences could be disastrous for your engine. Now remove the timing chain cover as well. For a short while screw in place the vibration damper bolt and turn the crankshaft with its help until the timing marks on both sprockets on crankshaft and camshaft line up. Both should be at twelve o'clock positon. Then proceed to removing camshaft sprocket bolts without making any attempt to turn camshaft in this process. Use two large screwdrivers to carefully pry off camshaft sprocket from camshaft dowel pin Slip timing chain and the camshaft sprocket off the engine. Timing chains and sprockets are sold as sets only. If you want to use a new timing chain, remove it with a puller but do not forget to replace the crankshaft sprocket with a new one. While installing line up key in crankshaft with keyway in sprocket. The guide-timing chain dampener-area needs inspection for cracks and wear; if necessary replace it (it is held onto engine block by two bolts). Clean them using solvent and blow dry them using compressed air if possible . Check these parts for wear or/and damage such as deformed teeth, chips, pits, cracks etc. Cam shaft needs turning until dowel pin reaches 9 o'clock position then meshing of timing chain hoop over cam shaft sprocket followed by engagement onto crank shaft sprocket where timing marks are supposed to be aligned. Tighten camshaft sprocket bolts. Coat the chain and sprocket with clean engine oil. Now install the timing chain cover. The remaining steps for installation are just the opposite of removal.

  Q: How to remove and reinstall the timing chain and sprockets in 2.3L four cylinder (Quad-4) engine for a Chevrolet Beretta?

  A: There are special tools which are required for this procedure; therefore, check it carefully before starting work. Firstly, disconnect the negative battery cable, taking precautions if the vehicle is equipped with the Delco Loc II audio system. Secondly, remove the coolant reservoir and engine lifting bracket at the drivebelt end. Next, remove vibration damper, upper and lower timing chain cover fasteners and detach the cover and gaskets from the housing. Slide oil slinger off crankshaft and temporarily reinstall vibration damper bolt for later use. Then rotate crankshaft clockwise to align camshaft sprocket's timing pin holes with housing holes by inserting 8 millimeters pins or bolts for alignment. Make sure that crankshaft sprocket mark lines up with engine block mark having keyway pointing up. Following removing timing chain guides, take away timing chain tensioner sleeve and spring in model through 1991 together with tensioner shoe after that. In addition, retract tensioner shoe using a wire on 1992 and later models. Then remove tensioner assembly followed by timing chain from sprockets beginning at exhaust camshaft sprocket. Remove camshaft sprockets as necessary ensuring proper identification using sealant on camshaft sprocket bolt threads. Also check alignment of camshaft and crankshaft sprockets to make sure correct valve timing.Slip timing chain over the sprockets; release intake camshaft alignment dowel pin; check timing marks.Adjust chain if needed.Install chain housing-to-block stud and tighten.Reset timing chain tensioner assembly to its "zero" position.Reinstall tensioner shoe, spring and sleeve.Remove alignment pins then rotate crankshaft clockwise two full turns aligning crankshaft timing mark with engine block mark and temporarily reinstalling eight millimeter alignment pins.Lastly, install remaining components in reverse order; check fluid levels; start engine and inspect for proper operation and leaks.
