Exclamation 2001 tacoma timing issues

So got myself into a pickle. changing timing belt on truck and everything line up perfectly and new belt looked great but after turning engine over several time by hand i realized that though my cam marks and crank marks lined up great at tdc the belt marks moved one tooth evry time i brought crank back around to tdc. am i correct in assuming there is an issue and if so whats the fix.

as long as the cams and crank shaft lines up with the marks you are fine, the marks on the belt are just for start point. I just did mine and ran into the same problem but the truck is running perfect.

it was already there. I had the same issue about the knocking sound but it has been fine. I even took the truck to a mechanic and he told me that the sound is normal for the trucks and I wasn't going to be able to get rid of it. You won't notice it in a couple of days. I don't know about the over heat issue, That sounds like a problem but I don't think that is timing belt related. Did you replace the thermostat and water pump?

any water leaks?

Exclamation

yeah i replaced water pump, tensioner, both idler pulleys and thermostat. the truck never knocked before i did the belt so im assuming that it has to be something i did, check engine light came on too so i figured maybe knock sensor unplugged but it didnt. Im now confused as to what to do next.

Did the cams move when you were installing the belt?

Are you sure that you don't have any water leaks? Did you install the thermostat gasket around it? Did you buy everything from the dealer?

the overheating issue is most likely an easy fix, my main concern is the dieseling sound and the check engine light. I work in a garage so guess ill attempt driving it to work and putting it on the scanner
