Aftermarket part numbers

Supplier articles whose catalogue lists 1 742 23. Check the supplier’s own restrictions before ordering.

What these parts’ suppliers state

Each value belongs to the part number beside it, not to the OE number: parts that list one OE number can differ. Where your vehicle manufacturer gives a value, it takes precedence.

Specification	Value and the part numbers stating it
Fitting position	Main Expansion Tank STELLOX 75-50955-SX

STELLOX: 75-50955-SXWeight: 64 g Colour: blackFitting position: Main Expansion Tank

Vehicle fitment

Engine code and production dates decide fitment. Model name and year alone don’t.

206 vehicles in 38 model series, inferred

Aftermarket parts that list 1 742 23 fit these vehicles according to their supplier catalogues. That does not prove 1 742 23 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
