• Automann: An excellent choice that balances durability and cost, designed specifically for the heavy-duty market

💎 Advantages of Our Premium Brand Deposits

• Industrial Grade Polymers: High-density, translucent materials that allow you to check the level at a glance, but are strong enough not to become brittle over time.
• Reinforced Ports and Connections: The hose inlets and outlets are designed not to deform under pressure, preventing annoying antifreeze leaks.
• Sensor Compatibility: Includes or allows for the exact installation of the level sensor, vital for receiving early warnings on the dashboard before overheating.
• Pressure Resistance: Designed to work in conjunction with the pressure cap, keeping the system sealed and preventing the coolant from boiling over.
• Perfect Drop-In Fit: They match the original mounting points exactly.

🔧 The Expert's Verdict

A yellowed or cracked coolant reservoir is a warning sign. It could burst at any moment due to pressure, leaving your truck stranded and risking damage to the radiator and engine. By installing a Dorman or Paccar reservoir, you protect your investment.

Signs that you need to replace your antifreeze reservoir:

• Yellowish or heat-discolored deposit
• Small surface cracks in the plastic
• Refrigerant leaks around the connections
• Tank deformation due to excessive pressure
• Level sensor not working properly
• Brittle material that breaks when touched

Benefits of using premium brand tanks:

• Elimination of leaks through cracks and deformations
• Precise control of the cooling system pressure
• Perfect compatibility with original level sensors
• Superior resistance to thermal expansion and contraction cycles
• Reinforced mounting points that resist engine vibrations
• Translucent material that allows for easy level verification

Installation recommendations:

• Always use a new pressure cap when installing a new tank
• Fill with high-quality antifreeze to prevent sediment buildup.
• Verify that all hoses are in good condition before installation
• Make sure the level sensor is properly connected
• Bleed the cooling system to remove trapped air
• Inspect the mounting points to ensure a secure installation
• Tighten all hose clamps according to specifications
• Check for leaks after filling the system

Installation Procedure:

• Wait until the engine is completely cold before starting
• Drain the coolant from the system into a suitable container.
• Disconnect the hoses from the old tank
• Disconnect the level sensor (if applicable)
• Remove the mounting screws or clips
• Install the new tank on the mounting points
• Connect the hoses and tighten the clamps.
• Install the new or existing level sensor
• Fill the system with new antifreeze according to specifications
• Purge the air from the system following the manufacturer's procedure.
• Check the level after the engine reaches operating temperature.

Cooling System Maintenance:

• Check the coolant level weekly
• Visually inspect the deposit for cracks or discoloration monthly.
• Check hose connections for leaks regularly
• Replace the antifreeze according to the manufacturer's recommendations (usually every 2-5 years)
• Inspect the pressure plug and replace it if it is damaged
• Verify that the level sensor is functioning correctly

Problem Diagnosis:

• Constant coolant loss: Inspect the reservoir for cracks and the hoses for leaks
• Engine overheating: Check the coolant level and the function of the pressure cap
• Low level warning light: Check the sensor and the actual coolant level
• Foamy refrigerant: May indicate air in the system or a faulty pressure cap

Pro Tips:

• Mark the correct level on the new tank for quick reference.
• Use antifreeze of the type and color specified by the manufacturer
• Do not mix different types of antifreeze without verifying compatibility.
• Save the part number of the deposit for future reference.
• Inspect the radiator and thermostat at the same time
• Consider replacing all hoses if they are more than 5 years old.
