If it pops back through intake then check for a worn cam or valve not opening. timing on ignition is not set.

This guide will help you install the timing belt

I have just replaced the water pump, timing belt, both idlers and tensioner pulley, and automatic tensioner on a 2001 mazda 626 2.5 litre. It started right up but almost immediately began to whine and the engine stalled out once. The pulleys and belt came in a kit (gates #tck214) The new automatic tensioner I put on is a cloyes #9-5324. It is a cast iron unit instead of aluminum. Is the belt too tight? Should I try using the old tensioner? The new one had more stickout but I checked online and this is the recommended part#. Please help. Thank you

Hi there,

This does sound like the tensioner is to tight, try the old tensioner and see how you go.

Thank you for replying. The old hydraulic tensioner puked oil when I compressed it to pin the plunger for reassembly. My understanding is this means replacement. The cloyes part had a stickout greater than that of the factory piece. Either there is some mid year cutoff or this part is manufactured wrong. I have a dayco replacement on order which is, from observation on the website, identicle to the factory aluminum piece instead of a cast iron replacement-same stickout. The cloyes had a lifetime replacement, the dayco one year. Go figure. Thanks

These things are sent to try us, as you said the old one is due to be replaced and the one that is noisy is over tensioning the belt, the replacement one I hope will solve all your problems,

Good luck,

Well I've taken the thing apart and replaced the tensioner with the correct one. The car starts and idles fine but now it makes the "whirring" sound as soon as you hit the throttle. This is my nieces car so i'm unsure if this is normal becuase i'm rarely in it. Is this normal or should it not be making this noise at any rpm? I realize that a cogged timing belt or any drivebelt of this type should emit some audible noise. Thank you in advance.

Hi there,

The V6 is a single cam (per head) engine the 4 Cyl is a twin cam, so i have added both just in case.

The cam gears will only fit on one way, place the cam gear on the shaft and lay the cam in accordance to where the alignment mark should be, you have a margin to work with at this point, so it dose not have to be exact until the belt is on, a few degrees at this point is not an issue, I hope that is a bit clearer.

I just noticed this post on a google search, this engine has 4 cams, MHPAUTOS (allegedly an expert). There is one sprocket that controls 2 cams each. His question is how to line up the pair of cams in each head.

Subject, camshaft timing alignment and timing belt alignment. When seting cams dot to dot, Ihave to rotate back cams(1 3 5)to align timing. Ex cam position is with lob straight up and the intake lob is at 9 o'clock instend of 3o'clock. The other cams did not have to be adjusted both int. And exh. With alignment dots pointing at each other. Both cams are set appox. At 8:30. This doesn't look correct.

I have a 2001 Mazda 626 LX. The other day I ran the car to the store and then when I want to get back in to drive home the car started and then turned off. I have had the spark plugs replaced, the gas filter replaced and the air flow censer replaced and it still is doing the same thing. Have also checked the timing belt looked it and it is fine. I have stumped the guy that works on my car, he doesn't know what it could be. Do you?

Check the fuel pressure if its within specs and injector pulses if okay-look for ignition spark
