Drive belt just broke


My V-shaped drive belt broke today, lucky I wasn't far from home. Will try to buy one tomorrow morning if stores are open otherwise will have to wait.

I wonder should I leave 1/2 or 3/4 inch deflection? I don't want to put it too tight nor too loose.

"Dad, which car are we taking?"                      "The Pontiac!"

"Which one?"                                                    "The red one!"

'06 Buick Allure

'12    Japanese minivan

I'm not sure what GM recommends. I always make them so that gentle pressure on the top of the belt in the middle of the span between pulleys would deflect maybe 1/2 an inch, no more than. You don't want it too awful tight or you'll find yourself replacing a water pump I'm betting.
