The Webasto 82553A Diesel Heater Coolant Pump is an essential component of Webasto heating systems for diesel-powered vehicles. This electrically driven, internally geared pump circulates coolant to ensure optimal performance and longevity of the diesel heater. Here is a detailed description of this product:
The Webasto 82553A Diesel Heater Coolant Pump features a compact design, making it easy to install and integrate into various vehicle types. With dimensions of approximately 7.5 x 4.9 x 4.2 inches (LxWxH), it can fit into limited engine compartment spaces. The housing is made of robust thermoplastic material, which offers both durability and resistance to corrosion.
The Webasto 82553A operates on a unique concept it uses an electric motor to drive the pump internally, eliminating the need for a separate drive belt. By doing so, the heater is more efficient and reliable, as the electric motor is directly connected to the pump. The motor requires 12V DC power and draws around 2.05 Amps at 13.8V to operate at full capacity.
The pump's impeller size is around 1.8 inches in diameter and delivers a maximum flow rate of approximately 2.66 gallons per minute (10 liters per minute). It is designed to handle coolant temperatures ranging from -4 F to 257 F (-20 C to 125 C). For the system to work effectively, the coolant should have a resistance of between 15,000 ohms and 20,000 ohms at 13.8V.
To rebuild the Webasto 82553A Diesel Heater Coolant Pump, the following parts may need replacement:1. Impeller: The impeller's blades may wear out over time, resulting in reduced pump efficiency. A new impeller assembly will ensure the pump operates at peak performance.
2. Seals: The seals can wear out due to prolonged use and high temperatures, leading to coolant leaks. Replacing both the outer and inner seals is crucial to maintaining the thermostat functionality and overall system effectiveness.
3. Motor: The motor can fail if the coolant gets contaminated or due to prolonged usage. In case of motor failure, it's recommended to replace the entire pump assembly, which includes the motor, impeller, and seals.
With a reliable, efficient, and easy-to-install design, the Webasto 82553A Diesel Heater Coolant Pump is an indispensable addition to diesel-powered vehicles equipped with Webasto heating systems. Regular maintenance and occasional rebuilding, when necessary, can keep it functioning optimally and prolong the life of the entire heating system.
