Question about 1997 Mazda 626

How to readjust the Timing Belt without removing the belt.

I have a very similar issue in trying to set the idle. There are two idle screws-one on the throttle plate and one in front vertically. Someone said they are the high and low idle. (?) I understand I’ll have to adjust the idle first utilizing the jumper from ten to battery ground. Got it around 800 - 850rpm and check my timing with the same setup and the timing mark is all the way to the far right of the timing bar. I loosing up my distributor and rotated from stop to stop with no movement of the timing mark. Remove the valve cover, top timing cover and rotated the crankshaft to TDC with #1 plug at dist as well and noticed the two cam marks are off one teeth. Is there an easy way to readjust the timing belt without going through the whole timing belt removal procedure? I feel this must be done first before the idle is set correctly, but hope that an adjustment for the camshaft timing belt can be done. Thanks in Advance!!!

Hi,i also have a 1997 maza 626,you it is reccommed that you change the timing belt and the water pump at the same time,if you just change the timeing belt,then the water pump will go and you would have to do it all over again,you would be paying double.The timeing belt is together with the water pump,so you have to change every 70,000miles....Shop around..i got one guy for 500,anthor for420 dollors,it could take one day max two,don;t pay over 500 dollor's for this....

Timing belt change on 92 bighorn 4jg2.bolts into both cogs, tdc etc.now it runs rough and heaps of smoke, checked timing belt 2x rotations back to tdc and bolts lined up Possibly pump timing?


fuel pumps ( diesel pumps) that are belt driven are spring loaded for the timing
you cannot remove and replace the belt as the pulley will move 1 tooth put of time
check where the timing mark on the pump pulley is when the crank and camshaft marks are on the spot and readjust to the mark where it should be

My kia wont start it seems to back fire on 1 exhaust stroke but it tries to start. but no go, timing belt and spring replaced timing set


According to DRE99gsx on supraforums.com who has similar problems: "btw, I found the problem, and SHE STARTED! After inspecting all 3 sensors, I determined that the crank sensor was the only unknown. I compared the intake cam with a stock intake cam to verify the cam sensor tabs were in the same locations, 180deg apart. They were. Since the sesnors and wiring all checked out, I then proceded to verify that the crank timing plate was in the right location. Well, it wasnt. After removing the timing belt covers, I noticed the timing belt was not using the entire crank timing belt gear. 1/8th of the belt was sticking out past the rear end of this gear.

Turns out the timing plate behind the gear was not pressed into the gear. I thought you slide on the plate, then the gear, and they press into each other (as long as the plate's tab lines with the gear's groove). I guess not. I removed them both and pressed them together in a vise, heard a click, and realized this could have been the issue.

The crank sensor was seeing erratic signals as I was turning the crank. I'm sure if I had an oscilloscope handy I could have caught this quicker, but through process of elimination, gold was scored.

Thanks for the help. She fired up and idled like it should. 80psi oil pressure (cold), fuel pressure was good, etc etc. "

I found a 2.0L VW engine for a Cabrio. Not sure if this is the right one, but here goes:

REMOVAL & INSTALLATION

NOTE: Do not turn the engine or camshaft with the timing belt
removed. The pistons will contact the valves and cause internal engine damage.

Gasoline Engines

Fig. 5: Loosen the tensioner bolt
91223p48.jpg







Fig. 6: Mark the belts direction of rotation
91223p52.jpg



  1. Disconnect the negative battery cable and remove the accessory drive belts,
    crankshaft pulley and the timing belt cover(s).
  2. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to
    TDC of No. 1 piston. The mark on the camshaft sprocket should be aligned with
    the mark on the inner timing belt cover or the edge of the cylinder head.
  3. With the distributor cap removed, the rotor should be pointing toward the
    No. 1 mark on the rim of the distributor housing. On 8 valve engines, the notch
    on the crankshaft pulley should align with the dot on the intermediate shaft
    sprocket.
  4. Loosen the locknut on the tensioner pulley and turn the tensioner
    counterclockwise to relieve the tension on the timing belt.
  5. Slide the timing belt from the sprockets.
    To install:

  6. Check the alignment of the timing marks. On 16 valve engines, the mark on
    the tooth should align with the mark on the rear belt cover.
  7. Install the new timing belt and tension the belt so it can be twisted 90°at
    the middle of it's longest section, between the camshaft and intermediate
    sprockets.
  8. Recheck the alignment of the timing marks and, if correct, turn the engine 2
    full revolutions to return to TDC of No. 1 piston. Recheck belt tension and
    timing marks. Readjust as required. Torque the tensioner nut to 33 ft. lbs. (45
    Nm).
  9. Install the belt cover and accessory drive belts.
  10. If the belt is too tight, there will be a growling noise that rises and
    falls with engine speed.


Diesel Engines

Some special tools are required. A flat bar, VW tool no. 2065A, is used to
secure the camshaft in position. A pin, VW tool no. 2064, is used to fix the
pump position while the timing belt is removed. The camshaft and pump work
against spring pressure and will move out of position when the timing belt is
removed. It is not difficult to find substitutes but do not remove the timing
belt without these tools.
NOTE: Do not turn the engine or camshaft with the timing belt
removed. The pistons will contact the valves and cause internal engine damage.



  1. Disconnect the negative battery cable and remove the accessory drive belts,
    crankshaft pulley and the timing belt cover(s). Remove the camshaft cover and
    rubber plug at the back end of the camshaft.
  2. Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to
    TDC of No. 1 piston. The mark on the camshaft sprocket should be aligned with
    the mark on the inner timing belt cover or the edge of the cylinder head.
  3. With the engine at TDC, insert the bar into the slot at the back of the
    camshaft. The bar rests on the cylinder head to will hold the camshaft in
    position.
  4. Insert the pin into the injection pump drive sprocket to hold the pump in
    position.
  5. Loosen the locknut on the tensioner pulley and turn the tensioner
    counterclockwise to relieve the tension on the timing belt. Slide the timing
    belt from the sprockets.
    To install:

  6. Install the new timing belt and adjust the tension so the belt can be
    twisted 45 degrees at a point between the camshaft and pump sprockets. Torque
    the tensioner nut to 33 ft. (45 Nm).
  7. Remove the holding tools.
  8. Turn the engine 2 full revolutions to return to TDC of No. 1 piston. Recheck
    belt tension and timing mark alignment, readjust as required.
  9. Install the belt cover and accessory drive belts.
  10. If the belt is too tight, there will be a growling noise that rises and
    falls with engine speed.

I want to change the timing belt of my car. Can you give me detailed instructions on how to do it.


I have pasted the instructions from autozone.com below, but I never recommend this chore for a novice. If the valve timing is not right, it can ruin your engine. If you have not done this before, I recommend you at least have a mechanic look at the belt before you close up the timing cover.


Removal & Installation

1.7L Engine
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Note the radio security code and the radio presets. Disconnect the negative battery cable.
  3. Rotate the crankshaft to set the engine at Top Dead Center (TDC) on the compression stroke for the No. 1 piston. The white mark on the crankshaft pulley should align with the pointers on the timing cover. Once the engine is in this position, it must not be disturbed.
  4. Raise and support the vehicle safely. Remove the front tires. Remove the splash shield. Lower the vehicle.
  5. Remove the power steering pump and position it to the side without disconnecting the hoses. Remove the alternator.
  6. Remove the ignition coil cover. Remove the four ignition coils. Remove the throttle cable clamps and harness holder mounting bolts. Remove the cylinder head cover. Remove the crankshaft pulley.
  7. Properly support the engine using a block of wood under the oil pan. Remove the upper bracket.
  8. Remove the grommet from the upper cover. Disconnect the camshaft position (CMP) top dead center (TDC) sensor connector.
  9. Remove the side engine mount bracket.
  10. Remove the crankshaft position (CKP) sensor from the oil pump, without disconnecting the connector.
  11. Apply slight force to the timing belt at the midpoint between the camshaft pulley and the water pump pulley and check that the auto tensioner moves smoothly, if not replace it.
  12. Move the auto tensioner to remove tension from the timing belt. Remove the timing belt.

  2. Set the camshaft to TDC. The UP mark on the camshaft pulley should be at the top. Align the TDC marks on the camshaft pulley with the top edge of the cylinder head.
  3. Install the timing belt in a counterclockwise sequence, starting with the drive pulley.
  4. As required, replace the auto tensioner assembly.
  5. Continue the installation in the reverse order of the removal procedure.
  6. Reprogram the ECM/PCM engine idle characteristics. Be sure all electrical items are OFF.
  7. Start the engine. Hold the idle speed at 3000 RPM-s in park or neutral until the radiator fan comes on or the temperature reached 194 degrees.
  8. Let the engine idle for about five minutes with the throttle fully closed.
  9. If the radiator fan comes on during the five minutes, do not count this toward the five minute programming time.
  10. Set the clock.

Need to know how to get the water pump out without removing the motor damn foreign cars. and lil handed men


i have never worked on a paseo, I presume that it is 4cylinder front wheel drive
A lot of the water pumps on the japanese cars are driven by the timing belt which is behind the plastic covers on the front of the motor
if it is similar to a holden astra you have to place a jack under the front of the engine to hold it up as you have to remove the front engine mount
loosen the alternator belt and remove the belt
remove the crankshaft pulley
remove the plastic timing covers top and bottom
remove the timing belt but make sure the cam gears do not move otherwise you have to set the timing up again
when the timing belt has been removed the water pump should be visible, possibly at the bottom left side looking at the engine from the side of the car
there may be 2 or 3 bolts holding the pump in, remove the bolts and the water pump should be able to pull out of the housing, there will be an "O" ring on the pump, make sure you put it on the new pump as it is a lot of work as you are about to find out if you have forgotten to do this
Here in Australia they want $1200 plus to do the timing belt on a holden astra without the water pump but it is best to replace the water pump when you replace the timing belt because of the work involved
took me about 5 hrs to do that job as I had never done one before
i hope this helps you in some way

Do timing chains need replacing after 100000kms on a Mazda Tribute 2001. Dealership says they do!


If you are experiencing issues with timing (backfiring, dieseling, rough idling, power loss, etc...) your timing chain might indeed need adjustment or replacement. If your vehicle is working without issues it's highly unlikely.
