Review on 🔧 ACDelco Professional Drive Belt Tensioner Assembly 38145 with Pulley by Douglas Davis

96 Impala SS . 81,000 km so now after almost 2 years and 4000 km this part of the ac delco has failed. Tension knot is a must. After the car sits for a few days, the tensioner binds when starting and then makes a loud growl. I swapped it and now it's fixed. It took me about 1 year to figure it out and with a 1 year warranty it's not a good deal only 4000 miles. tested the new tensioner without binding. don't buy, won't last long.
