Review on 🔧 ACDelco Professional Drive Belt Tensioner Assembly with Pulley - 39112 model by Epickson Palma

This is an EXACT OEM replacement part for BMW n52 engines. It comes in an Acdelco box but has the same markings as the original part removed from the car including "Made in Germany" and all the casting marks except the more recent date of course. That's at least half the price you'll find elsewhere. You will need to replace the mounting screw as it is a torqued aluminum piece. I paid 4€ for the screw at the dealer. Super easy 15 minute job to replace this with a 328 using only T60 and E14 sockets.
