Expert:  Tim's Auto Repair replied 3 years ago.

hi

it should have the silver and gold links..

if your chain doesn't have the gold and silver links..the crank mark will go a 6 o'clock,,the cams will line up with the chain backing plate[the rear cam at 11 o'clock the front at 1 o'clock

this may help..this is the instructions for both engine types

thanks

    Be careful not to confuse the intake and exhaust camshaft sprockets. The exhaust camshaft sprockets are thicker than the intake camshaft sprockets.

    1. Remove the pins from the camshaft chain tensioners.
    2. Install the main timing chain on the crankshaft sprocket and water pump sprocket. Then install the camshaft drive sprockets as shown in the illustration. Dip the camshaft sprocket bolts in fresh engine oil and torque them to 88-95 ft.lbs. (119-128 Nm.).

      1. Install the chain guides. Install the main timing chain tensioner.

      After checking that all of the mating marks on the chains and sprockets are correct, temporarily install the crankshaft damper and SLOWLY rotate the engine by hand at least one full revolution to verify the camshaft/crankshaft timing is correct. If the crankshaft stops suddenly, a piston is hitting a valve. Do NOT force the engine to rotate; bent valves will result. Check the mating marks on the sprockets and the chains, and perform any procedures as necessary to correct misalignment.

      1. Apply liquid gasket to the timing chain cover as shown in the illustration.
      2. Following the tightening sequence shown in the illustration, tighten the timing chain cover bolts to the specified torque.
      3. Apply liquid gasket to the water pump cover and install it to the front timing chain cover.
      4. Install the rocker (valve) covers.
      5. Install the intake manifold collector.
      6. Install the upper and lower oil pans.
      7. Install the exhaust header pipe.
      8. Install the engine mount and bracket.
      9. Install the center member assembly. Remove the engine from the hoist.
      10. Install the crankshaft damper.
      11. Install the crankshaft and camshaft position sensors.
      12. Install the A/C compressor and bracket to the engine block.
      13. Install the power steering pump.
      14. Install the accessory drive belts and the idler pulley.
      15. Fill the engine with the appropriate quantity of engine oil and coolant.

      The engine may produce a rattling noise when it is started. Run the engine at around 3,000RPM in neutral to purge the air from the hydraulic chain tensioner.

      1. Start the engine and check for leaks from the sealing surfaces.
      2. Install the timing chain cover.
