I need help finding a manual, for a 2001 pontiac aztek engine. Can you help?

Hi Joel, you’re going to want to go to Helminc.com this is the source for factory service manuals. Then under the place that says “Vehicle owner, do-it-yourself, & professionals” hit the button that says “click here”. On the next screen look to the upper left corner, there is a search box there for item numbers
enter gmt01b and click the “go” button under the box. This should bring up the manual that you want. However they are not cheap so be prepared for it! I think they are $135.00 plus shipping. Other than that you may try the dealer, some of them will help you out and let you look through their manual and make you a copy of what you need.
Hope this helps, good luck!
