Prevent Costly Coolant-Oil Mixing with a Precision Oil Cooler Gasket

Safeguard your excavator’s engine from catastrophic coolant leaks and oil contamination with the genuine VH157171320A Oil Cooler Element Gasket. This critical sealing component is engineered as a direct OEM replacement for the interface between the engine block and the oil cooler on J05E and J08E engines. Specifically designed for Kobelco SK200-8, SK210LC-8, SK250-8, SK260LC-8, and SK330-8 models, a failing gasket can lead to coolant entering the engine oil or vice-versa, causing severe engine damage. Ensure a perfect, leak-free seal and maintain the integrity of both your cooling and lubrication systems.

Product Overview

The VH157171320A Oil Cooler Element Gasket is a precision-formed seal that sits between the engine block (or timing gear case) and the oil cooler assembly. Its primary function is to create separate, sealed channels for engine coolant and engine oil to flow through the oil cooler’s heat exchanger core without mixing. This gasket withstands exposure to both hot coolant and hot engine oil, as well as significant temperature cycling. Our replacement gasket is manufactured from high-quality, multi-layer steel (MLS) or composite materials with a heat-resistant coating, ensuring it maintains a reliable seal under the pressure and thermal stresses of continuous operation, preventing costly cross-contamination.

Key Features & Benefits

• Precision OEM Fit: A direct replacement for part number VH157171320A, guaranteeing perfect alignment with all coolant and oil passages, bolt holes, and sealing surfaces on your J05E or J08E engine block and oil cooler.

• Prevents Catastrophic Engine Damage: A reliable seal is crucial to prevent coolant from mixing with engine oil (or oil entering the coolant). Such mixing can cause loss of lubrication, overheating, bearing failure, and complete engine seizure.

• Dual-Fluid Resistance: Specially formulated materials resist degradation from both ethylene glycol-based coolants and engine oil, ensuring long-term sealing integrity in a challenging environment.

• Withstands Extreme Conditions: Designed to maintain its shape and sealing force under high temperatures and pressure differentials, preventing leaks that could lead to low coolant or oil pressure warnings.

• Essential for Cooler Service: This gasket is a mandatory replacement item whenever the oil cooler is removed for cleaning, repair, or replacement. Reusing an old gasket is not recommended and risks immediate failure.

• Cost-Effective Insurance: This small, inexpensive part protects against one of the most expensive and damaging failures an engine can experience, making it vital preventative maintenance.

Frequently Asked Questions (FAQ)

Q1: What are the symptoms of a failed oil cooler gasket (VH157171320A)?
A: Key warning signs include:

• Coolant in the engine oil: Oil appears milky, creamy, or frothy (like a chocolate milkshake) on the dipstick or under the oil cap.

• Engine oil in the coolant: Coolant in the overflow tank appears oily or sludgy.

• Low coolant level without an obvious external leak.

• Overheating due to loss of coolant or oil contamination reducing cooling efficiency.

• Low oil pressure warnings.

Q2: Is this gasket sold individually or as part of a kit?
A: The VH157171320A is typically sold as an individual gasket. For a complete oil cooler service, you may also need the O-rings for the cooler end caps, which are often sold separately or in a master seal kit.

Q3: Can I install this gasket myself?
A: Replacing this gasket requires significant mechanical work. It involves draining coolant and engine oil, removing the oil cooler assembly from the side of the engine block, thoroughly cleaning both mating surfaces, and reinstalling with the new gasket using the correct torque sequence. Recommended for experienced mechanics.

Q4: Why must this gasket be replaced and not reused?
A: The gasket compresses permanently during initial installation to form the seal. Once removed, it cannot regain its original shape and sealing force. Reusing it will almost certainly result in a leak and potential engine damage.

Q5: Should I clean or replace the oil cooler when changing this gasket?
A: It is highly advisable. If the gasket failed due to age, simply replace it. However, if the failure was due to poor maintenance or contamination, the oil cooler’s internal passages may be clogged. Have it cleaned or pressure-tested, or replace it if necessary, to ensure proper cooling function.
