Hello all on the other hand I recently changed the timing belt with my Peugeot 106 S2 Sport 1.4L (Bj. 2000) with the water pump and tensioning roller (from Gates) and since then it is crying in the engine compartment with cold engine quite unbearably. Here is a video that I have recorded: Peugeot 106 howls from the engine roomDescription of the problem: It only howls with cold engine and the noise is dependent on speed (starts at approx. 1,300 rpm, becomes louder and higher frequency and stops at 2,200 rpm). About 5-10 minutes drive you don’t hear anything anymore and if I leave the car only 1 hour or so and then drive again, you don’t hear anything. But if the engine is completely cold again (so leave it for several hours, especially overnight) the game starts from the front again and it is whistling again…Trying problem solutions: In order to narrow down the source of noise more precisely, I left the car at night without V-belts and in the morning the noise was still present: so Keilrie I also slightly loosened the timing belt yesterday (previously it was about 60° with the “rotation test”, now it is 90°), but the problem persists. So I think that only the water pump or the tensioning roller are still in question (the WaPu has a plastic shovel). What do you think? Thank you in advance Dear Greetings,
