It's not possible that the belt was loose if your car ran fine. Since the repair, the car has had lingering problems. If a timing belt breaks, the engine will stall, and in some cases, might even need expensive additional repairs. The symptoms are as follows: severe vibration whenever the car comes to a stop (it seems to be related to the suddenness of drop in RPM) at idle with the gear engaged in 'D' (~600 RPM). Sounds like it misfires a bit at idle. car has got 315km as for timing marks i didn't check it but thought about it and i will just been -10C all week and car is in a back yard however last time i checked timing belt about 20k ago about 3-4 months and looked like new and i bought the car at 260km and last owner told me it was just done. In some cases, the belt may simply need tightening. Throttling causes bogging and/or the engine to die. After replaceing belt and fixing leak the car idles rough and rpm's drops low and stalls within 5 seconds of starting unless I give it a little gas. The timing belt, or cambelt, ensures the camshaft and crankshaft rotate in sync while opening and closing the engine valves during the fuel intake process.
