Questions About the Catalogue

Is this the whole range

No. 178 references are published here out of a cooling-system range of more than 4000 types. If the number you need is not listed, send it and we check it against the range.

How is the catalogue organised

By part family first — intake, charge air, coolant, radiator, thermostat and flange — then by vehicle make inside each family. The same product can be reached from either route.

Can I order across families in one shipment

Yes, and most buyers do. A mixed pallet across families travels on one packing list and one freight cost.

Do the listed OEM numbers mean the parts are original equipment

No. The OEM numbers identify which original part the replacement is built to interchange with. They are identification references, not a claim of original equipment supply.

What if two references look identical

They often do. Connector geometry, bellows pitch and opening temperature separate them, which is why the reference and not the photograph decides the order.
