Aenmcs 55564441 - Set of 3 Piston Cooling Oil Jets

Aenmcs 55564441 - Piston Cooling Oil Jet Set

Oil jets (piston cooling injectors) are small metal parts installed in the engine block whose job is to direct a stream of oil under the pistons to cool them and provide additional lubrication. The set contains three metal jets intended as direct replacements for the original parts.

Uses

The set fits engines installed in many GM/Opel models, including Chevrolet Cruze, Epica, Sonic, Aveo, Orlando, Tracker and Malibu, as well as Opel Mokka, Meriva-A, Insignia-A, Zafira-B, Astra-H/J, Corsa-E and Saab 9-5. It matches the original part number 55564441. Because the same jet is used across many models and engine variants, it is worth comparing the part number with your old jet before buying.

When to replace oil jets

A clogged or damaged oil jet limits piston cooling, which during long, intensive engine operation can lead to overheating pistons and accelerated wear of the piston rings. Jets are usually replaced during deeper engine work, for example when replacing the oil pan or repairing the crank and piston assembly, when there is direct access to the engine block.
