1252970 Core As-Oil Cooler — Cat 320B 320C

Name: 1252970 Core As-Oil Cooler — Cat 320B 320C
Brand: CAT
SKU: 1252970
Availability: InStock

This is the core of an oil cooler, a heat exchanger responsible for reducing the temperature of engine oil circulating through the system. It is built to meet OEM specifications, ensuring efficient heat dissipation and maintaining optimal oil viscosity for lubrication, unlike a damaged or clogged core that compromises engine protection. Operators may observe a rise in engine oil temperature, increased oil pressure, or a warning light for high oil temperature when the oil cooler core is failing.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing oil cooler core is often an elevated engine oil temperature reading on the dashboard gauge. If ignored, this can lead to the oil becoming too thin, reducing its lubricating properties and potentially causing increased engine wear. The worst consequence is severe engine damage due to overheating and inadequate lubrication.

Installation Tip

Ensure all sealing surfaces are clean and that new O-rings or gaskets are used to prevent oil or coolant leaks. Do not overtighten the mounting bolts, as this can distort the cooler core.

Service Note

Flush the oil passages thoroughly and inspect the engine oil for signs of coolant contamination when replacing the oil cooler core.
