•Can I order a radiator for an excavator if the OEM part is discontinued?
Yes — this is a core specialty of several plants in this section. Provide the machine model and either the OEM part number or the old radiator's measurements: core height, width, thickness, tank and connection layout. The factory builds an analog, typically in copper-brass, with a pressure-test certificate. Production usually takes two to four weeks.
•Which is better for hot climates: copper-brass or aluminium cores?
Both work if correctly sized. Aluminium is lighter and cheaper; copper-brass dissipates heat slightly better per volume, tolerates higher fin-clogging from dust, and crucially can be repaired by soldering in any local workshop. For machines far from parts supply, repairability often decides. Many buyers run aluminium in cars and copper-brass in heavy equipment.
•How are radiators protected against transit damage to the fins?
Export packing uses individual cartons with rigid face boards over the core, then crating or palletizing with vertical separators. Fin damage in transit is the main claim category for this product, so photograph each unit at unstuffing before signing delivery documents. Suppliers accustomed to export will provide packing photos and accept properly documented claims.
•Are water pumps and fans sold matched to the radiators?
They can be ordered together, and for heavy-equipment rebuilds it is wise: a new high-density core with a worn pump or slipping fan clutch underperforms. Suppliers will bundle pump, fan, hoses and expansion tank against your engine model. For passenger-car references each component is simply ordered by its own part number.
•What does a typical lead time look like for a mixed cooling-parts order?
Catalogue radiators for common Russian vehicles ship from stock within days. Heavy-equipment analogs are made to order in 15–30 days. A mixed consolidation — say stock items plus three custom cores — usually dispatches within a month, then 30–50 days sea transit or two to three weeks overland to Central Asia. Air freight cuts urgent single radiators to about a week.
