And those "rubber" bands did contract when heated. Now, I dont intend to go back and research all this, but, IIRC, there is a whiff of truth in the basic statement. Let's just say that there are rubbers (latices) and elastomeric compounds which we call rubber. I am interested in the concept, but not enough to make an issue of it. BUT, his concept is flawed. The problem is almost certainly a worn or improperly tensioned belt.

From: condor_222 on 19 Feb 2010 00:55 Right, it's not a timing belt. My bad. Good catch. Thanks for the detailed instructions. I appreciate it! I'll see if there are tools around to do it on my own. Some misunderstandings about rubber and cold. I'll make another post about what really cold weather actually does to cars in the winter.
