    I see no visual signs of drying out. Also no signs of cracks of any kind. Age is unknow vut not older than 5years (since its previous replacement was at 184k odoMeter And it was supposed to be replaced at around 274k (90k interval) lpg fuel in netherlands is only for people who drive arround 10k or more a year.
    if any fuyher info is wanted i can ask previous owner (if he replies)

Do a history check on the engine as the belt may have been change earlier without being recorded
If it is the original belt, a change is recommended any way along with all idler pulleys , oil seal and hydraulic tensioner

    It is the 3th timing belt kit (1th was changed around 85000km's. The 2th kit was on there from 85000km's till around 174###km's. So this set would have to be changed at 274000km . Since previous owner aas a mazda chief mechanic i would believe what he said about the timing b. Kit.
    I have a complete kit but my mechanic says to change the water/coolant pump considering it has probably the original one.
    what is usualy the amount of km's a timing belt actually lasts ?

  • Bill Boyd Apr 22, 2015

    there is no exact period or mileage for timing belts but manufacturers specifications is 100.000 klms or 60.000 miles

  • Bill Boyd Apr 22, 2015

    any thing more than that is chanchy to say the least. from your figures ,the last belt was fitted at at 174.000 klms then the next belt would be due at 274.000 klms. if it has 300.000 klms on the clock then it is well due for a belt change. if the water pump has to be removed to do the change or the belt drives the pump then yes ,it would be a good idea to do the pump as well

  • Frank Teunissen Apr 22, 2015

    in europe its 90000km's belt is the same so why the difference (its not like we live in the desert here haha.. no extreme weather type).
    Asked my mechanic. He said if it feels like it looks replaxe it, he thought it had some sort of wave like structure. I told him it only looks that way.)

  • Frank Teunissen Apr 22, 2015

    No the Waterpump is not driven by timing belt.
    though when it fails the timing belt has to be removed to change the pump.

re-install belt, lining up the timing marks, crank to TDC #1 cylinder, cma pulleys have marks on them, line them up to the index marks as well. If you have a drive wheel in the air, you can pop the car into 5th gear (make sure it's chocked!) and rotate the wheel to turn the engine for alignment, etc. You can put a wrench/socket on the cam bolt to align it as well.

You are probably better off taking it to an authorized dealer. This job require some specian tools and you would also have a warranty with the work.

At what mileage must the timing chain/belt be replaced?

Now a days, timing chains are usually good for the life of the engine. However, timing belts are usually recommended between 60,000 and 100,000 miles.
It will be good to know if your engine is "interfering" or "non-interfering".
That means, if the belt breaks, will it destroy the engine (interfering) or not (non-interfering).
God bless your efforts.

Why does my 1997 mazda 626 die after I rev on the engine once. There check engine light is not on

I have not had a Mazda but in cars I have had it seem to be something which reminds me of timing belt which has slipped a tooth. If your car has a timing belt and has not been changed at the recommended mileage it would be something to check into. Most of my vehicles have been GM and I have had to change 3 timing belt all before 65,000 miles. It never did any damage to my engine but as I understand foreign cars have closer tolerances and can damage valves and pistons. I am sorry I can't be of more help. If your car has not lost any power other than what you have stated it is probably not the timing belt.

2000 mazda 626 driving down highway then just dies.. timing belt or fuel pump/filter?

By you saying the engine "Dies" I am going to assume it restarts.
If the timing belt failed the engine would not start again until the belt was replaced.
So it could be a fuel or electrical problem.

Timing belt problem

No,the 1996 Mazda 626 is not a interfearance engine, meaning that the valves will not hit the pistons if the belt breaks while underway but the engine will not run untill the belt is replaced.

Timing belt

You should replace your timing belt as regular maintenance. I usually will let the belt go to 80k for the 1st one. The rest of the time, I recommend replacing it every 60k. The reason being is that the factory timing belt is much superior to the replacement belts. I don't like to push the belt to it's absolute limit because if it breaks while you're driving the car, expensive engine damage may occur. I consider it "cheap insurance".

Slipped timing belt

First off, if it slipped, you desparately need a new belt.

You may be able to locate timing marks on the cam gear and crankshaft pulley but you would be better off buying the Haynes or Chilton repair manuals to avoid mistakes.
Unless your engine is a 'non-interference' engine, you may end up trashing at least the valves if not the entire head if you don't get it right.
Most engines can tolerate a tooth off in either direction without damage.
My summer toy car, an '87 Bertone, can run this way but it is really weird- either no revs and pulls like a tractor or wild revs with no torque.
