Rattling soung after changig timing belt of Mazda

could have been a loose belt to start with. check alt and water pump. if alt is not noisey and charging. check water pump for leaks and noise. make shore belt is in good condision and the correct tension

timing belts should be checked every 20,000 miles and replaced every 50,000 but sounds like you need a new thermostat and your valves are going bad

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?

YES, AND YOU SHOULD REPLACE THE TIMING BELT AT THE SAME TIME .

every 90,000 to 100,000miles and yes it is strongly recomended to replace the water pump with it

well get ready cuz ur not gonna like it in order to change the water pump you must remove the top left motor mount then remove all the belts and plastic covers you can get to then pull the harmonic balancer and acc belt tensioner then then remove the rest of the plastic covers take off the timing belt and tensioner pulley assembly then u can remove the water pump install is reverse of tear down but make sure you get the block clean and replace the timing belt too otherwise that water pump wont matter cuz you'll meed a new enginge when that belt breaks

The reason is the water pump is driven off the timing belt, extra parts and allot more labor. No the eng does not have to be removed, labor time around 4 hours, parts about, about $125 US for parts, if it is a dealer add $75 US

replacement of timing belt $350-$500. aftermarket shops will try to sell you a package containg a belt, water pump, and tensioner pulley. the dealer will just replace the belt, they might recommend to replace the water pump if there are alot of miles on the car, they will also inspect the pulley for wear.

usually a good time to change it is at about 100,000 miles. change it before it becomes a must or not ride(type of thing). if your water pump is run by your timing belt, then yes you should change the water pump when you do the timing belt. the tension from the new belt will sooner than later kill the bearing in the old water pump and it will cost you twice to fix it versus the one time fix. when you go in to the shop there should be no additional cost to replace the timing belt because it has to come off to replace the water pump.
