Can i remove the timing chain tensioner from the top of the motor on a 2000 cavalier 2.2l or is that only with a dual cam?


Hi Friend:

Your Timing Chain Tensioner is located in the Lower Front of your engine.

#1) you'll have to disconnect your negative Battery cable.

#2) Remove the Top Engine cover to give you better access to the Front of Engine.

#3) Then you'll need to remove your alternator and with wiring attached put it off to the Side you might have to tie it with a wire to secure it.

#4) then you'll need to remove your Power Steering Leave the Lines on it and Put it to the sideas well , Tie off if necessary.

#5) then Jack up the front of your car,make sure you Put Good Stands under the car to keep it secure.while you work under it.

#6) then remove the TWO front Oil Pan Bolts Only the very 2-Front ones.

#7) Then directly above the Oil pan front of the Engine you'll see your Crank Shaft Pulley Remove it, You will need a Puller to Remove it.then the Timing Chain Cover, There are Several bolts Holding it on to the front of the Engine.

#8) Remove ALL the Bolts on Timing over, then Take cover Off,It could be a Little Stubborn ,if All bolts are out for sure, Take a Small plastic mallet and Tap the Cover Easily,until it comes off.

#9) Now before you remove anything else there is a Timing Mark on the Cam Shaft and one on the Crank Shaft,NOTE: BESURE you line them marks up,The Cam Shaft Mark should be pointing Straight Down--And the Crankshaft Mark needs to be Pointing Straight up.and Lined up with the Top Timing Mark.If the are Not

NOTE: Rotate the Engine by Hand Turning the Sprockets until they are LINED Up.

Then Take off the Top Cam Shaft Mounting Bolts,then Pull Sproket and timing Chain at the Same Time.

Then Loosen the Chain Tensioner Bolt with out taking it ALL the Way OUT. then remove your Chain Tensioner.

If your this far i Recommend that you Replace The Timing Chain,Cam Sproket and Crankshaft Sproket as well.

If not the Install your new Chain Tensioner,And Just Simply Reverse the Un-Install Directions.To Put All back Together.

Do Replace the Timing Cover Seal. Using Proper Seal Remover and Installer.

Also before you put your Timing cover back on CLEAN the Surfaces of the Engine and the Cover.And Use a Gasket Sealer and Mount to Block ==Lining Up ALL your Timing Cover Bolt Holes. Let it set a Short time a Few Minutes at Least. To prevent Slipping when installing your Timing Case Cover.

1- Last Thing Torque your Timing Chain Tensioner at 89 Inch Pounds.Which rewuires a Torque Wrench.

And Torque ALL your Timing Cover Bolts at 97 Inch Pounds.Do NOT Over Tighten You'll Strip them.

MAKE Sure the Timing Marks are Still lined up.

This will get your Timing Chain Tensioner Replaced. Thanks for using FixYa From: d_hubbs

Does my 2001 saturn sl 1.9l have a timing belt or chain?


It is a chain and its not the easiest but it could be worse.It is as follows:
1.9L SOHC Engine
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the engine oil.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Right front wheel and splash shield
    NOTE: Place a 1 in. x 1 in. x 2 in. long block of wood between the torque strut and cradle to ease removal and installation of the torque engine mount.
    • 3 right side upper engine torque axis to front cover nuts and the 2 mount to midrail bracket nuts, allowing the powertrain to rest on the block of wood
    • Drive belt, tensioner and pulley
    • Power steering pump attaching bolts and set the pump to the side with the lines still attached
    • A/C compressor from the bracket and set aside with the lines attached
    • Camshaft cover
    • Using a strap wrench or a piece of wood wedged between the damper spoke and the lower side of the engine front cover, hold the damper and remove the bolt. With a suitable 3-jaw puller and the slots cast into the damper, pull the crankshaft damper/pulley assembly from the crankshaft.
    • Install the special oil seal replacement tool SA9104E, to be sure the front crankshaft timing sprocket is held firmly in place and prevent guide damage. Install with the flat side towards the crankshaft sprocket.
    • Remove or disconnect the following:
      • Front 4 oil pan bolts and cut the seal away from the front cover
      • Front cover bolts and carefully pry the cover away from the cylinder block at the pry location tabs, which are provided. Remove the cover from under the hood or through the wheel well
      • Front cover oil seal from the cover
      NOTE: During timing chain and sprocket removal, position the crankshaft 90 degrees past Top Dead Center (TDC), to be sure the pistons will not contact the valves upon assembly.
    • Carefully rotate the crankshaft clockwise so the timing mark on the crankshaft sprocket and keyway align with the main bearing cap split line (90 degrees past TDC).
    • Remove or disconnect the following:
      • Timing guides and tensioner
      • Camshaft sprocket bolt, using a 7⁄8 in. (21mm) wrench to hold the camshaft. Then, remove the timing chain and camshaft sprocket
      • Crankshaft sprocket
      To install:
    • Inspect the chain for wear and damage. Check the inside diameter of the chain, it should be no more than 16.77 in. (426mm). Inspect the chain guides for wear or cracks and the timing sprockets for teeth or key wear. Replace components as necessary.
    • Verify that the crankshaft keyway is positioned 90 degrees clockwise past TDC (keyway at 3 o'clock). The keyway should align with the split between the bearing cap and engine block.
    • Bring the camshaft up to No. 1 TDC by loosely installing the sprocket and rotating the sprocket until the timing pin can be inserted. The camshaft contains wrench flats to assist in turning the shaft. The dowel pin should be at 12 o'clock when the camshaft is at TDC.
    • Install the crankshaft sprocket, then rotate the crankshaft counterclockwise 90 degrees up to No. 1 TDC (keyway at 12 o'clock).
    • Position the chain under the crankshaft sprocket and over the camshaft sprocket. The timing chain should be positioned so that 1 silver link plate aligns with the reference mark on the camshaft sprocket and the other aligns with the downward tooth (at the 6 o'clock position) on the crankshaft sprocket. The letters FRT on the camshaft sprocket must face forward, away from the cylinder head and excess chain slack should be located on the tensioner side of the block.
    • Install or connect the following:
      • Timing pin to verify proper alignment of the camshaft and sprocket. Torque the sprocket bolt to 75 ft. lbs. (102 Nm).
      NOTE: Do not allow the camshaft retaining bolt to torque against the timing pin or cylinder head damage will result.
      • Timing chain guides with the words FRONT facing out. Install the fixed guide first and verify the chain is snug against the guide, then install the pivot guide. Torque the bolts to 19 ft. lbs. (26 Nm) and verify that the pivot guide moves freely
      • Retract the tensioner plunger and pin the ratchet lever using a 1⁄8 in. No. 31 drill bit inserted in the alignment hole at the bottom front of the component
      • Tensioner. Torque the bolts to 14 ft. lbs. (19 Nm), then remove the drill bit
    • Make one final check to verify all components are properly timed, then remove all timing pins.
    • Install or connect the following:
      • Seat a new front cover oil seal using the installation tool with a press
      • If the engine front cover casting or assembly is replaced, the 3 torque axis mount studs should also be replaced. Torque the new studs to 19 ft. lbs. (25 Nm).
1.9L (DOHC) Engine
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. drain the engine oil.
  3. Remove or disconnect the following:
    • Negative battery cable
    • Right front wheel and splash shield
    NOTE: Place a 1 x 1 x 2 in. (25 x 25 x 51mm) block of wood between the torque strut and cradle to ease removal and installation of the torque engine mount.
    • 3 right side upper engine torque axis to front cover nuts and the 2 mount to midrail bracket nuts, allowing the powertrain to rest on the block of wood
    • Drive belt, tensioner and pulley
    • Power steering pump attaching bolts and set the pump to the side with the lines still attached
    • A/C compressor from the bracket and set it to the side with the lines attached
    • Camshaft cover
  4. Using a strap wrench or a piece of wood wedged between the damper spoke and the lower side of the engine front cover, hold the damper and remove the bolt. With a suitable 3-jaw puller and the slots cast into the damper, pull the crankshaft damper/pulley assembly from the crankshaft.
  5. Install the special oil seal replacement tool SA9104E or equivalent, to be sure the front crankshaft timing sprocket is held firmly in place and prevent guide damage. Install with the flat side towards the crankshaft sprocket.
  6. Remove or disconnect the following:
    • Front 4 oil pan bolts and cut the seal away from the front cover
    • Front cover bolts and carefully pry the cover away from the cylinder block at the pry location tabs, which are provided. Remove the cover from under the hood or through the wheel well
    • Front cover oil seal from the cover
    NOTE: During timing chain and sprocket removal, position the crankshaft 90 degrees past top Dead Center (TDC), to be sure the pistons will not contact the valves upon assembly.
  7. Carefully rotate the crankshaft clockwise so the timing mark on the crankshaft sprocket and keyway align with the main bearing cap split line (90 degrees past TDC).
    • Timing guides and tensioner
    • Camshaft sprocket bolt, using a 7⁄8 in. (21mm) wrench to hold the camshaft. Then, remove the timing chain and camshaft sprocket
    • Crankshaft sprocket

My 97 cavalier needs a new water pump. it has a2.4 l dohc 5 spd. do i have to remove the timing chain cover to fix?


yes you must remove the timing chain cover, timing chain, timing chain case, and exhaust manifold, takes about 6 hrs to change, I know I got the same motor and car, good luck and have fun, also you will need to buy a gasket set for the timing chain

Timing chain on 2000 Jaguar


The jaguar v8 has 4 timing chains located on the front of the engine behind the aluminum timing cover.
You can inspect them by remove the valve covers but to replace them you need special factory tools to set the vehicle up on TDC.
The secondary timing chain tensioners are a common failure on this vehicle which will cause the chain to break.
You can replace the tensioners to prevent this failure just by removing the valve covers and exhaust sprocket, but if this is not the issue the chains should be lifetime, not like a timing belt which is required to be replaced by time and mileage.
