Blue Print ADC49908 Radiator Cap for coolant expansion tank, pack of one

Product Overview

The Blue Print ADC49908 Radiator Cap is a precision-engineered sealing component designed for the coolant expansion tank of Mitsubishi Smart and Colt vehicles. This single-piece cap provides reliable protection against leaks, corrosion, and pressure fluctuations within the cooling system.

Key Features

• OEM Quality: Manufactured to match original specifications, ensuring a perfect fit on models such as the Mitsubishi Smart Forfour, Colt VI, and related variants.
• Durable Construction: Made from high-grade plastic that resists heat, chemical exposure, and mechanical wear.
• Pressure Resistance: Rated to handle up to 14 bar, safeguarding the expansion tank against overpressure conditions.
• Sealing Integrity: Equipped with a robust gasket system that prevents coolant leakage and maintains optimal pressure balance.
• Easy Installation: Designed for quick, tool-free fitting—simply align and secure to restore the cooling system’s integrity.

Compatibility Matrix

The ADC49908 cap is engineered to fit a wide range of Mitsubishi Smart and Colt models. Below is an overview of compatible vehicles:

Installation Guide

1. Locate the coolant expansion tank on your vehicle’s engine bay.
2. Ensure the tank is cool and depressurize if necessary by gently opening the existing cap or using a pressure relief tool.
3. Clean the rim of the tank to remove any debris or old gasket material.
4. Place the ADC49908 cap onto the tank, aligning the screw holes with the mounting points.
5. Screw the cap in place until it is snug but not overtightened—over-tightening can damage the plastic seal.
6. Verify that the cap sits flush and that no coolant leaks are present.

Performance Benefits

Installing a high-quality radiator cap such as the ADC49908 offers several advantages:

• Maintains System Pressure: Keeps the cooling system at the correct pressure, which is essential for efficient heat transfer.
• Prevents Overheating: By allowing expansion of coolant without pressure loss, it reduces the risk of overheating.
• Extends Component Life: Protects hoses, seals, and the radiator from excessive stress caused by fluctuating pressures.
• Reduces Maintenance Costs: A reliable seal eliminates frequent checks for leaks or pressure drops.

Material & Design Specifications

The cap’s construction uses a blend of high-impact plastic and reinforced polymer, chosen for its thermal stability and resistance to automotive fluids. The gasket material is engineered to withstand temperatures up to 120°C while maintaining a tight seal against coolant chemicals.
