There should be a belt tensioner on that vehicle, i belive its the Hydralic Belt Tensioner, you will have to 1st loosen a 14mm nut on the belt tensioner pulley then rotate it i belive counter-clock wise to slacken the belt, then tighten that 14 mm nut to hold the tensioner back away from the belt , once you remove the belt you will have to remove the hydralic tensioner also to reset it before the new timing belt can be installed. MAKE SURE you are able to HOLD both camshafts the inner cam sprocket it spring loaded and can jump out of timing if you are not careful.
make sure when u do install the belt to rotate the engine over 2 or 3 times to make sure you have correct lineup of all the timing marks. this will insure you do not bend any valves.

Somehow my camshafts were moved while replacing timing belt. Best way to recover? 96 Sebring jxi 2.5 v6 HELP!!!!


the engine has been identified as an intereference engine and that means every possibility of valve damage
to recover , loosen of the valve adjusters or loosen of the cam shaft caps so that the valves are all closed before you rotate the crankshaft to TDC
then reset the cam shaft/s timing marks and do it all back up and hope that no valves are bent

Where is the water pump on a 96 vienta?


That will be a V6. The water pump is behind the timing belt, which has to be loosened and pushed aside. You may as well replace the belt as well. See here p320

How do you retime a timing belt for a Chrysler Cirrus 1995 V6


Position the number one cylinder at TDC. Take the hot side terminal off. Remove the drivebelts. Loosen the large bolt in the center of the crankshaft pulley/damper. After removing the crankshaft pulley, reinstall the crankshaft bolt using an appropriate priate spacer (this will enable you to turn it later) Remove the upper-left timing belt cover. Remove the lower timing belt cover. Detach the power steering pump bracket from the engine. Remove the right (passenger side) engine mount and the mounting bracket from the engine. Make sure the engine is supported with a floor jack placed under the oil plan. Place a wood block on the jack head to prevent damaging the oil pan. Loosen the timing belt tensioner mounting bolts and then remove the tensioner. Carefully slip the timing belt off the sprockets.This is a good time to check the crank and camshafts for leaks. Make sure your marks are lined up before you put it back together. Best wishes.

How to tighten /loosen belts on a 2000 xterra, its making a super loud squeaking noise when i turn on the car


The only cure to fix squeaking belts, is to replace with the new one. When the belts start squeaking noise, then it is the time to check the status of the timing belt or chain, depending on the size of the engine.
The 2000-2004 Nissan Xterra was offered with the choice of 2.4L 4-cylinder or 3.3L V6 engine.
The 2.4-liter 4-cylinder DOHC engine was a pretty good reliable engine, but for this truck, it was underpowered. This engine has a long-lasting timing chain - there is no timing belt to replace.
The 3.3-liter V6 SOHC was also a bit slow on pick-up, but for daily use, it was pretty good, durable, simple engine. This engine has a timing belt that needs to be replaced at recommended intervals. The SE model offered a supercharged version of the same engine with more power.

How to install the timing belt to a 2001 nissan frontier 3.3L v6 after the heads have been removed and replaced.


From autozone.com

f99936c.gif
To install:


CAUTION Before installing the timing belt, confirm that the No. 1 cylinder is set at the TDC of the compression stroke.

  1. Remove both cylinder head covers and loosen all rocker arm shaft retaining bolts.



NOTE The rocker arm shaft bolts MUST be loosened so that the correct belt tension can be obtained.

  1. Install the tensioner and the return spring. Using a hexagon wrench, turn the tensioner clockwise and temporarily tighten the locknut.
  2. Be sure that the timing belt is clean and free from oil or water.
  3. When installing the timing belt, align the white lines on the belt with the punchmarks on the camshaft and crankshaft sprockets. Have the arrow on the timing belt pointing toward the front belt covers.



NOTE A good way (although rather tedious!) to check for proper timing belt installation is to count the number of belt teeth between the timing marks. There are 133 teeth on the belt; there should be 40 teeth between the timing marks on the left and right side camshaft sprockets, and 43 teeth between the timing marks on the left side camshaft sprocket and the crankshaft sprocket.

  1. While keeping the tensioner steady, loosen the locknut with a hex wrench.
  2. Turn the tensioner approximately 70-80 degrees clockwise with the wrench, then tighten the locknut.



WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

  1. Turn the crankshaft in a clockwise direction several times, thenslowly
  2. Apply 22 lbs. (10 kg) of pressure (push it in!) to the center span of the timing belt between the right side camshaft sprocket and the tensioner pulley, then loosen the tensioner locknut.
  3. Using a 0.0138 in. (0.35mm) thick feeler gauge (the actual width of the blademust12slowly!12
  4. Slowly rotate the crankshaft clockwise several more times, then set the No. 1 piston to TDC of the compression stroke.
  5. Position the 2 timing covers on the block, then tighten the mounting bolts to 24 ft. lbs. (35 Nm).
  6. Press the crankshaft pulley onto the shaft, then tighten the bolt to 90-98 ft. lbs. (123-132 Nm).
  7. Connect the radiator hose to the thermostat housing.
  8. Reconnect the fresh air intake tube at the cylinder head cover.
  9. Install the air conditioning compressor drive belt idler pulley and bracket.
  10. Install the distributor protector (dust shield).
  11. Install the spark plugs.
  12. Install the power steering, air conditioning compressor and alternator drive belts.
  13. Install the radiator.
  14. Reconnect the water pump hose and fill the engine with coolant. Install the fan shroud and pulleys.
  15. Install the engine undercover.
  16. Start the engine and check for any leaks.

I am having troubles locating the cam shaft timing marks on my 1999 VW passat VR6 engine. any ideas


hi, here is a guide i have come across on this site written by another expert it should be the one for your engine but always double check.

If you are unsure what you are doing then please go out and buy a haines workshop manual as these tell you every detail you need to know so that would be your best solution.

Please dont do this work if your unsure what you are doing as you could damage the engine beyond repair so you have been warned;

it covers single cam and if you scroll down it shows double cam ok

Timing chain or belt?


The 2002-2006 Camry received the next generation 2.4L 4-cylinder engine (model 2AZ-FE), which combines decent power with excellent fuel economy. This engine does not have a timing belt, it has a chain that does not need to be replaced.
The second choice is very smooth and powerful 3.0-liter 24-valve all-aluminum V6 engine.
Starting from 2004, the 3.3-liter V6 DOHC VVT-i engine is available on SE V6 model.
Both, the 3.0L and 3.3L V6 engines have a timing belt that must be replaced at certain interval
