Land Rover Part Number: PQG500030 - Primary Drive Belt Tensioner
PQG500030 is a Primary Drive Belt Tensioner. Fitted to the accessory drive on 4.2 supercharged and 4.4 AJ V8 engines, this pulley locates and applies controlled force to the primary auxiliary drive belt to maintain correct running tension and alignment between the crankshaft pulley and accessory pulleys such as the alternator, power steering and air conditioning drives. Correct tension reduces belt slip, limits uneven wear and helps avoid premature belt failure; replacing a worn or noisy tensioner restores predictable belt routing and accessory drive engagement.
