Serpentine Belt Tensioner with Pulley for GM Trucks & SUVs (1999-2009)
A replacement belt tensioner assembly for the GM full-size truck and SUV family and the badge-engineered models built alongside them. A tired tensioner usually gives itself away with belt squeal on start-up, a rattle or chirp from the front of the engine, or visible belt flutter at idle, and left alone it chews through belts and can leave you without charging or power steering. This unit is manufactured to OE specifications and ISO quality standards, with a spring designed to hold tension longer than the worn original, and every unit is factory tested.

FAQ
Is the pulley included? Yes, the tensioner comes as an assembly with its pulley.
What are the symptoms of a failing tensioner? Belt squeal on start-up, a chirp or rattle from the front of the engine, and belt flutter at idle.
Why are so many different badges listed? These GM trucks and SUVs, along with the H2, Rainier, Ascender and 9-7x, share the same engine accessory drive.
Should I replace the belt at the same time? It is worth inspecting it while the tensioner is off, as a worn tensioner is hard on belts.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.
