Oil Cooler 1W5033 for Caterpillar
Product Introduction: Oil Cooler 1W5033 for Caterpillar Equipment
Overview
The Oil Cooler 1W5033 is a precision-engineered component designed for Caterpillar equipment, specifically used to regulate engine oil temperature by dissipating heat, ensuring optimal lubrication and extending engine life. This oil cooler is critical for maintaining engine performance and preventing overheating in demanding applications, primarily marine and industrial engines like the D353. Available as a new aftermarket or genuine OEM part, it provides a reliable and cost-effective solution for engine maintenance.
Key Features
- Material: Constructed from high-grade aluminum or stainless steel, designed to withstand high temperatures, resist corrosion, and perform reliably in harsh operating conditions. Features a robust core with efficient heat transfer surfaces.
- Design: Precision-engineered oil cooler, typically a shell-and-tube or plate-type design, built to OEM specifications for precise fitment and performance. Optimized for cooling engine lubricating oil, reducing wear on critical components like bearings. Includes gasket kit for installation.
- Compatibility: Compatible with Caterpillar equipment, specifically:
- Engines: D353 (6-cylinder, turbocharged diesel engine, 24.1L displacement, used in marine and industrial applications).
- Equipment:
- Marine Propulsion: Caterpillar marine vessels powered by D353 engines.
- Industrial Applications: Generator sets and pumping units. Typically used in the engine’s lubrication system to maintain oil temperature. Exact model compatibility must be verified using the equipment’s serial number via CAT SIS, as compatibility cannot be confirmed without it per Caterpillar’s policy.
- Dimensions: Specific dimensions are not publicly detailed but conform to OEM standards for the D353 engine, ensuring a precise fit. Typical oil coolers for large diesel engines measure approximately 12-24 inches in length and 6-12 inches in width.
- Quality Assurance: Manufactured in ISO 9001-certified facilities to meet or exceed US OEM specifications. 100% tested before shipping to ensure reliability.
Benefits
- Enhanced Engine Longevity: Efficiently cools engine oil, maintaining viscosity and lubricating properties, reducing wear on bearings and extending engine life in rugged marine and industrial environments.
- Reliable Performance: Prevents overheating, ensuring consistent engine performance (e.g., 400-600 hp for D353 engines) and minimizing the risk of catastrophic failure due to oil breakdown.
- Cost-Effective: Offers a high-quality aftermarket or OEM alternative, lowering maintenance costs compared to replacing entire engine assemblies. No core charge required.
- Ease of Installation: Engineered as a direct-fit replacement with included gasket kit, streamlining the repair process and minimizing downtime during engine maintenance or rebuilds.
Applications
The Oil Cooler 1W5033 is designed for use in Caterpillar equipment, specifically suited for:
- Marine Propulsion: Caterpillar marine vessels powered by D353 engines, for propulsion in commercial and industrial applications.
- Industrial Applications: Generator sets and pumping units for power generation and fluid transfer in mining, oil, and gas industries.
- Industries: Marine, power generation, and industrial sectors, where D353-powered equipment operates under high-load conditions.
Technical Specifications
- Part Number: 1W5033 (cross-referenced as 1W-5033, CA1W5033).
- Unit of Measure: Each.
- Condition: New aftermarket or genuine OEM.
- Weight: Approximately 10.0-20.0 lbs (4.54-9.07 kg), estimated based on similar oil coolers for large diesel engines (e.g., 7N0128 at 13.7 lbs).
