Hello, I recently bought a used (2003)Premacy Diesel and noticed that when it is cold, it gives noises of itself, which have nothing to do with the diesel nailing. More precisely, it sounds like a quiet shiver (about 2 times per sec) in the left half of the engine compartment (if you stand in front of the car). At the Mazda workshop, a belt was allegedly changed, but the noise remained unchanged. The friendly Mazda-Mechanist explained to me that e r is a roll that gets light rust similar to a brake disc and a bit scrubs until the covering is gone. Rust after a night?! I would be happy about any answer. VERY SOGAR 🙂
