Just did this on my XJS, remove the ditributor (mark where the rotor is pointing). Unbolt the two bolts holding the old tensioner in place. Pull the old tensioner out.
Pull the piston out of the new tensioner and coat with motor oil. install the new tensioner with the arrow pointing upward, make sure the slot for the tensioner blade is in the same position as it was when you pulled out the old one.
Bolt the new tensioner in place, torque bolts to 21lbs. Reinstall the distributor.
Crank the engine a few times before putting the coil wire back on to prime the new tensioner with oil pressure.
That's it, done.
To install the timing chain tensioner on a 2003 Chrysler 300M, first ensure the engine is at top dead center (TDC) on the compression stroke. Remove any components obstructing access to the timing chain cover. Install the new tensioner in its designated location, ensuring it aligns correctly with the timing chain, and then torque it to the manufacturer's specifications. Finally, reassemble any removed components and check for proper operation before starting the engine.
No, timing chain doesn't need replacing.

The timing chain tensioner bolt sticks out the back left side of the cylinder head. Take the timing chain cover off on the left side of the motor too see the inside to the chain tensioner.
It has two chains. CAUTION: At no time, when the timing chain(s) are removed and the cylinder heads are installed, may the crankshaft and/or camshafts be rotated. Failure to follow these directions will result in valve and/or piston damage. NOTE: Because this is not a free-wheeling engine, and it jumps time, there will be damage to the valves and/or pistons and will require the removal of the cylinder heads. The camshaft sprockets should only be disassembled from the camshafts when one of the components is to be replaced. Remove Valve Covers, Oil Pan and Engine Front Cover. Remove crankshaft position sensor pulse wheel. Rotate engine to No. 1 top dead center (TDC). Remove two bolts retaining RH timing chain tensioner to cylinder head and remove timing chain tensioner. Remove RH timing chain tensioner arm. Remove two bolts retaining RH timing chain guide to cylinder head and remove timing chain guide. Remove RH timing chain from camshaft sprocket and crankshaft sprocket. Remove two bolts retaining LH timing chain tensioner to cylinder head and remove timing chain tensioner. Remove LH timing chain tensioner arm. Remove two bolts retaining LH timing chain guide to cylinder head and remove timing chain guide. Remove LH timing chain from camshaft sprocket and crankshaft sprocket. CAUTION: Do not rotate crankshaft and/or camshafts or possible engine damage may occur. Inspect the plastic running face on timing chain tensioner arms and timing chain guides. If worn or damaged, remove and clean oil pan and oil pump screen cover and tube. Installation NOTE: If engine has jumped time, make sure that all repairs to engine components and/or valve train have been made. Then rotate engine counterclockwise 45 degrees. This will position all pistons below top of deck face. Install Cylinder Heads as outlined. Locate the copper links on the timing chains. They will be 180 degrees apart fro one another on each chain. When installing the chains on the gears, line one copper link on the chain with the alignment mark on the crank gear, and line up the other copper link on chain with the cam gear mark on each respective side of the engine. On the crank gear, both chains line up to the same mark. Install timing chain guides . Install timing chain guide retaining bolts. Tighten to 8-12 Nm (71-106 lb-in). NOTE: Crankshaft sprockets are identical. They may only be installed one way. Install LH timing chain on camshaft sprocket. Make sure copper link of timing chain lines up with timing mark of camshaft sprocket. Install LH timing chain on crankshaft sprocket. Make sure copper link of timing chain lines up with timing mark of crankshaft sprocket. Install RH timing chain on camshaft sprocket. Make sure copper link of timing chain lines up with timing mark of camshaft sprocket. Install RH and LH timing chain tensioner and secure with two bolts on each. Tighten bolts to 20-30 Nm (15-22 lb-ft). Lubricate timing chain tensioner arm contact surfaces with clean engine oil, and install RH and LH timing chain tensioner arms on their dowels. With a suitable C-clamp around the timing chain tensioner arm and timing chain guide, remove all slack from timing chain while using caution not to bend the timing chain guide. Remove lock pins from timing chain tensioners and make sure all timing marks are aligned. Install Engine Front Cover, Oil Pan and Valve Covers. Start engine and check for leaks and proper operation.
To install a chain tensioner on your bicycle, first, remove the rear wheel. Then, attach the tensioner to the frame or derailleur hanger. Adjust the tensioner to align with the chain and ensure proper tension. Finally, reattach the rear wheel and test the chain tension before riding.
The 2.2 ecotec motor has a timing chain with oil pressure tensioner and chain guides.
The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray

Refer to the procedure in this section. # Remove the three nuts and the engine support insulator through bolt from the engine support insulator. Remove the front engine support bracket (6028). # Raise and support the vehicle. # Align the crankshaft sprocket (6306) to TDC by turning the crankshaft (6303) in the direction of normal engine (6007) rotation. # NOTE: Remove the lower timing chain tensioner arm bolt before the upper timing chain tensioner arm bolt. Remove two bolts from the timing chain tensioner arm (6285) in the order shown. Remove the timing chain tensioner arm. # Mark the direction of rotation on the timing chain/belt (6268) to be sure of proper installation. # Loosen the timing chain/belt tensioner bolt. # Remove the timing chain/belt. Installation # Compress the timing chain tensioner arm until the hole in the piston is aligned with the second hole in the case. Insert a 1.6mm (0.06 inch) diameter wire or pin through the second hole to keep the piston compressed. # Align the camshafts (6250) to top dead center (TDC). # Turn the crankshaft clockwise until the crankshaft sprocket is offset from TDC by one tooth. # Install the timing chain/belt.Turn the crankshaft in the direction of normal engine rotation without moving the camshafts, until the crankshaft timing mark is again at TDC. This will place all of the belt slack in the timing chain tensioner arm portion of the timing chain/belt. # Install the timing chain tensioner arm and both bolts. Tighten the timing chain tensioner arm bolts to 19-25 Nm (14-18 lb-ft). # Remove the pin from the timing chain tensioner arm. # NOTE: When correctly timed, the crankshaft timing mark will line up and will NOT be one tooth off. Turn the crankshaft two complete revolutions, in the direction of normal engine rotation, to make sure that the timing is still correct. # Tighten the timing chain/belt tensioner bolt to 35-51 Nm (26-37 lb-ft). # Install the RH engine support insulator. Tighten the three nuts to 74-103 Nm (54-76 lb-ft) and the RH engine support insulator through bolt to 67-93 Nm (50-68 lb-ft). # Install the Engine Front Covers . |}
does jaguar x-type 3.0 have a timing chain or belt. and at what milage does it need to be changed.
To reset the timing chain tensioner on a 1999 Pontiac Grand Am, first, ensure the engine is cool and the battery is disconnected. Remove the timing chain cover to access the tensioner. Compress the tensioner using a suitable tool, then secure it in the compressed position with a pin or similar device. Reinstall the timing chain cover and reconnect the battery before starting the engine to check for proper operation.
It's a load of a job,Remove radaitor, all hoses, pullys, belts,Valve covers, timing chain tensioner and guides. replace pump which is run off the timing chain. Make sure to line up the 3 marks on timing chain so you have correct timing. Reinstall tensioner and make sure it is recharged(all the way out) Turn engine by hand with a wrench to make sure chain is tight and timing is correct(Very important). Reassemble engine in reverse order. This would be a good time to replace the timing chain and tensioner if over 100,000 miles, good luck.
