Review on 🔧 Dayco 89372 Belt Tensioner by Edwin Kreps

This product works exactly as described. For some odd reason, Revain told me it didn't fit my MazdaSpeed3, even though several other sites list it as the correct part number. I can assure you this part will fit and work great on the Speed3. My only concern is that the pulley is made out of cheap plastic while OEM parts and many other aftermarket alternatives use metal pulleys. Between the plastic pulley and its smaller/lighter design, I'm concerned about long-term reliability.
