Noise after thermostat change

Recommended Posts


I recently changed my thermostat using a mobile mechanic. Car now warms up fine, however there is now a small rattle noise from the engine from around idle that doesn't get any louder with revs. I believe he said he removed the belt tensioner at the top of the engine on the left side? Should I therefore be confident in that it's the belt tensioner making the noise? As I've read they make a small noise before failure and isn't too uncommon.
