Repaired timing belt, water pump, and pulley resister. On a 1998 Mazda 626 2.0 engine. Now it hesitate when taking off and loses power not only on hills, but also on level ground. What the heck is wrong?

* 1994 and newer Audi 2.8L V6;
* 1998 & up Audi 1.8L;
* All BMW 2.5L and 2.7L 6-cylinder;
* All Hyundai 4-cylinder and V6 engines;
* Infiniti 3.0L V6;
* Isuzu 1.5L, 2.0L, 2.3L & 2.6L engines;
* Kia 2.0L in the Sportage,
* Mazda 2.0L in the MX-6 and 626, and the 3.0L V6 in the 929 and MPV;
* Most Mitsubishi engines, except the 1.8L, SOHC 2.0L 4-cylinder & SOHC 3.0L V6;
* All Nissan 4-cylinder and V6 engines;
* All Porsche engines;
* 1989-'94 Suzuki 1.3L DOHC;
* Toyota 1.5L Tercel engine;
* 1990-'92 Volkswagen 1.6L diesel; and
* Volvo 2.3L and 2.4L engines.
Unfortunately, the owners of many of these vehicles are totally unaware that their timing belt needs to be periodically replaced for preventive maintenance. The belt is out-of-sight and out-of-mind and, unless they read their owner's manual (which few ever do) and see the replacement recommendation in black-and-white, they usually ignore the belt until it's too late.

YES! Straighten out the T belt & look for any misfires. If u have any spring loaded pulleys or tensioners, REPLACE THEM. Did U have a misfire before u did the work?

REMOVAL & INSTALLATION

2.3L/2.5L Engines
(see Figure 1 - click over pic for zoom)

Fig. 1: Timing belt cover on the 2.3L/2.5L engine

1. Disconnect the negative battery cable.
2. Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.
   

Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.

1. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
2. Loosen and position the power steering pump mounting bracket and position it aside.
3. Remove the timing belt outer cover retaining bolts and any interlocking tabs and remove the cover.
   

To install:

1. Install the timing belt cover.
2. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
3. Position the alternator and drive belts, then adjust and tighten it to specifications.
4. Connect the negative battery cable.

Hope helps (remember to rated this answer).

it's either your losing pressure in your head... check your vacuum... it's causing no pressure in your engine which its losing power causing the belts to idle out of tune..

as the timing belt usually turns the water pump yes it is possible. i am not sure what motor you have in this but i would think you ar elooking at your serpintine belt as your timing belt is behind plastic covers and is not visable. maybe your serpintine belt runs the water pump and as it is loose then it will not spin the water pump causing it to overheat

If you need instructions, do yourself a favor and have it repaired by a shop that works on Mazda's. You will want to replace the water pump and oil seals. its not a job for Backyard Bob.

What they mean is there is no obvious problems. What else runs off that belt? Check for misalignment there. What makes it break? Does it happen after a long trip ( 2 hrs. highway driving) or at timed intervals ( every month, 6wks)?
Carefully check all the pulley's for sharp edges or bump outs into the belt. If you find anything use a small file and smooth them out. They can cut or pinch your belt and weaken it so it breaks over time.
Check the pulley alignment with the engine running where you can see all the pulleys and belts at the same time. This might mean crawling under the car. Vary the engine speed while you watch and take it up to cruising speed. You are looking for something to change, i.e a pulley to start wobbling. It could be a mounting bracket that bends at higher revs that needs to be replaced or strengthened.
Hope this helps.

hi from uk the 626 water pump is not driven by timing belt but by another drive belt so easy to change after removal of under wing cover to access /see pump b4 you remove drive belt would advise you to slacken off the water pump pully 1st while it is held by drive belt to prevent turning ? then with belt off /pully removed pump is more accessable hope this helps?

does the water pump run off the timing belt or auxillary (fan) belt? maybe timing belt has slipped some teeth?

Hicksashley,

When you look at the engine on the pulley end you must find a triangular pointer on the main pulley and then look at the two or four cam pulleys for a dot like dent on the fin of the pulley. These are marks for timing, firstly you set the main pulley with the timing mark on the pulley to the triangular mark on the engine just above the pulley to the right or to the left, then you put both cam mark facing each other on the insides level with the top of the block. that it you should be able to start her up if your plug timing is in order,
