803079522 Hydraulic Oil Cooler for XCMG XE370CA Excavators

803079522 identifies a hydraulic oil cooler used as an application reference for XCMG crawler excavators. The cooler removes heat from the hydraulic oil and works with the machine's fan and ducting. Core size, port positions, mounting points and brackets must match the machine configuration; appearance alone is not a sufficient ordering check.

● Replacement of a leaking or damaged hydraulic oil cooler after related system faults have been separated

● Hydraulic oil overheating after fan drive, airflow, ducting and oil level have been checked

● Quotations that must state whether brackets, hoses, fittings and seals are included

803079522 is the reference part number used to identify and review this product. XCMG identifies the equipment application and does not automatically define the brand of every quoted unit. The formal quotation states the supplied brand, condition, assembly scope and included or excluded components.

The application reference for this page is the XCMG XE370CA crawler excavator. Final fitment must be checked against the complete machine identification, old-unit identification and relevant interfaces. Do not order by appearance or reference part number alone.

● Complete machine serial number and ID plate

● Old cooler label or markings, if visible

● Core length, height and thickness measured on the removed cooler

● Inlet and outlet port positions, thread type and direction

● Mounting holes, brackets and fixing points

● Fan shroud, ducting and sealing arrangement around the cooler

Coolers of similar appearance may differ in core size and thickness, port position and direction, mounting points, bracket arrangement and the way they seat against the fan shroud. These dimensions must be checked on the removed unit. Overheating can also involve fan drive, blocked airflow, oil condition and the heat load of the circuit, so the cooler should not be treated as the only possible cause.

According to customer requirements and current sourcing conditions, potential solutions may include a verified genuine option when available, a branded replacement or an aftermarket replacement. Availability is confirmed for each enquiry.

● Actual supplied brand and product condition

● Cooler assembly scope and whether brackets, hoses, fittings and seals are included

● Port and mounting configuration shown in the quotation photos

● Required quantity

● Warranty terms for the selected option

● Lead time for the quoted supply

For quotation, send the XE370CA machine identification, old-unit identification and the clearest interface photos.

● Measure core size, port positions and mounting points on the removed cooler.

● Confirm whether brackets, hoses, fittings and seals are included.

● Check fan drive, airflow and ducting before replacing the cooler.

● Check oil condition and flush the circuit where required so debris does not damage the new cooler.

A hydraulic oil cooler has a thin core and exposed ports. Port openings are sealed, the core faces are protected against bending and impact, and the cooler is supported in a rigid pack so that transport loads do not act on the core or fittings.

The shipping method, freight and estimated transit time will be confirmed according to the quantity, packed dimensions, weight and destination.

Warranty terms depend on the selected supply option and will be stated in the formal quotation. Actual pre-shipment photos can be provided.

Based in Xuzhou, China, VTS focuses on construction machinery parts supply and fitment support for international buyers.

● Fitment support focuses on the serial number, core size, port positions and direction, mounting points and bracket scope.

● The quotation distinguishes the supplied brand, condition, included components and assembly scope.

● Confirmed related excavator parts can be consolidated, with international shipping coordinated for the actual order.

How is 803079522 fitment confirmed?

Send the machine serial number, photos of the old cooler and its ports, and the core size measured on the removed unit.

Does the quotation include brackets and hoses?

Only when the quotation lists them. Hoses, fittings and seals can be quoted separately.

Can a cooler of similar size be used?

Not without checking the ports, mounting points and fan-shroud fit.

Does overheating prove the cooler is faulty?

No. Fan drive, airflow, oil condition and heat load also need to be checked.

Should the circuit be flushed?

Flush as the machine service procedure requires when contamination is present, so debris does not reach the new cooler.

Can the cooler ship with other excavator parts?

Yes, where practical, with the core protected and not loaded by other items.

For quotation, send the XE370CA machine identification, old-unit identification and the clearest interface photos.
