I recently replaced the water pump, timing belt, and thermostat. now.....

Hello, Take it from me, you are much better off removing it now and finding out what you missed. I once put a timing belt on with the teeth on, noticed that one of the small idler pulleys were not in the kit, ordered it, replaced it and bolted everything in a hurry, just to hear a motorcycle like noise. I had routed the timing belt on the wrong side of that pulley. Mistakes happen, just take your time next time. When installing the timing belt or chain, and after you think the alignment is correct, turn the engine in the normal direction of rotation 4 times. If the marks are still lined up, torque and recheck everything and bolt it up.
