Protect the turbocharger

After intense operation, the turbine temperature can exceed 600°C. After the engine is turned off, the main water pump stops, but the auxiliary electronic water pump continues to operate for 3 to 5 minutes and cools the turbocharger continuously to prevent spontaneous combustion due to overheating.

Adapt to traffic jams

During traffic jams in summer, if the air conditioner runs at full blast but the engine operates at low RPM, a traditional water pump is unable to supply sufficient coolant. Activating an auxiliary electronic water pump can provide an additional coolant flow of about 30 L/min, thus preventing the engine from overheating.

Support start/stop system

When the vehicle starts or stops, the mechanical water pump stop running, and the auxiliary electronic water pump takes over its role to maintain coolant circulation and prevent heat buildup.

Common failures:

1. Improper sealing causes coolant leakage.

2. The CP board overheats and burns out, preventing normal operation of the product.

Failure causes:

1. Circuit failure: poor circuit board wiring, capacitor aging, and burnout of devices.

2. Pump body failure: aged and damaged seals.

3. Other failures: motor and bearing failures.

To address common failures of original auxiliary electronic water pumps, vika has developed its own vika STO auxiliary electronic water pump featuring great improvements, with a warranty of 4 years or 150,000 kilometers!

1. The integrated circuit board of STO auxiliary electronic water pump features a unique design, and is manufactured with placement machines imported from Japan. The problem of high-temperature burndown has been effectively addressed;

2. The inner diameter of the water inlet of STO auxiliary electronic water pump is enlarged by 3 mm , and consequently the water flow is increased by 23%;

3. The head of STO auxiliary electronic water pump is based on a full R-angle transition design, which leads to smooth water discharge, high pressure resistance, and excellent heat dissipation;

4. The head and body of STO auxiliary electronic water pump are assembled using fully automatic torsional power control wrench of Siemens, and is subject to 100% air tightness testing to ensure good sealing without water leakage.
