I have taken out my engine. Rebuilt the head and am finally throwing it back together but not starting it probably for a couple months. Should I put my new belt on or will that be bad because it is so cold (in new york) that if it sits tight in one spot then I start using it it may snap? Someone please fill me in. I can't move much further which is why I would like to put it on but would not want to put it all together then take it apart in the spring because it is stretched and will not last. Thanks!

I've never heard of a timing belt snapping because of the issue you're fearing. You shouldn't have any problem installing it now. -
Leaving the belt tight in one spot over a period of months won't stretch out one side or anything?Comment

Put it on now. There's no risk of stretching in certain spots - and it prevents the MUCH greater risk of the cam, oil pump and crank sprockets moving around and valves kissing pistons if the belt were left off.101

How would it increase the risk of valves hitting pistons? Everything will be tdc of course. I have it set pretty close right now just can't move forward until it's on. Thanks for the responses guys!Comment

Buddy, think about how much force the engine is putting on the belt when it is running (or you revving the hell out of it). Sitting the belt will not cause any sore spot. If you are that cautious then just put the old belt on there for now.Comment

If your work area is like mine - things get bumped and moved around over a few months. "Unbelted" sprockets would be no different. Sure you would reset everything to TDC when you eventually install the belt - but why not finish the job now while everything is fresh in your mind.101
