FAQ
Q: How do I confirm this Oil Cooler Cover fits my Caterpillar E320 excavator? A: The most accurate method is to check the part number on your current oil cooler cover. Look for a stamped or cast number. If it matches 2552904 or 125-2971, this part is a direct fit. Alternatively, provide us with your engine serial number (e.g., S6K prefix) for verification. While this cover is designed for the S6K engine family used in E320 models, variations exist between machine serial number ranges.
Q: What are the signs of a failing oil cooler cover? A: Common symptoms include visible oil leaks around the top or side of the oil cooler housing, engine oil contamination (milky appearance if coolant mixes), or fluctuating oil temperatures. A warped or cracked cover can bypass oil from the cooler, leading to overheating. If you notice oil dripping from the front of the engine near the radiator area, inspect the oil cooler cover gasket and the cover itself for damage.
Q: Do I need to replace the gasket when installing this new cover? A: Yes, we strongly recommend replacing the oil cooler cover gasket (or O-ring) at the same time as the cover. The sealing surface is critical for preventing leaks. A new gasket ensures a proper seal against the machined surface of the new cover. Always clean the mounting surface on the engine block thoroughly before installation and torque the bolts to the manufacturer’s specifications.
