Replacing one pulley is the perfect time for a comprehensive service of the accessory drive. Always replace the multi-ribbed belt along with the pulley to ensure a perfect fit and avoid premature wear. Also, check the condition of the other pulleys (alternator, water pump) for damage.
The idler pulley, driven by the serpentine belt, is responsible for the proper guidance and tension of the belt that drives key engine components such as the alternator and water pump. Its failure leads to the belt breaking and immediate immobilization of the machine.
Replace the pulley before a broken belt causes serious damage. Common symptoms include:
✓ Avoid Sudden Downtime: The GX-AFTER Solution
A failed pulley bearing leads to a broken belt, which immediately stops the charging and cooling of the engine. The GX-AFTER pulley is a smart choice that allows you to prevent a serious failure at a low cost. Made of durable materials and equipped with a high-quality bearing, it ensures reliability and peace of mind.
Do you hear a disturbing noise from the engine? Don't ignore the warnings!
A squealing belt or a whining bearing is the last call before the machine is immobilized. Order a new pulley today and perform a simple replacement before it's too late!
No, this offer is for the complete pulley assembly. The belt should be purchased separately, and we always recommend replacing it at the same time.
2. I hear a squeal, but I don't know which pulley is noisy. How can I check?The simplest method is to remove the belt (with the engine off!) and manually spin each of the pulleys. A damaged bearing will make a rumbling or grinding noise, or will have noticeable play.
3. Does this pulley fit the version with air conditioning?No, this model is designed for machines without an A/C compressor. The belt routing on A/C versions is different and requires different pulleys.
