What are the symptoms of a failed Mercedes-Benz coolant pipe?

06-11,2025

Mercedes-Benz coolant pipes provide key channels for connecting core components in a cooling system such as radiator, engine, and auxiliary radiator. They are mainly distributed in the upper part of the engine, radiator ports, turbine pipelines, and other locations. The most frequent failure of Mercedes-Benz coolant pipes is leakage, especially on vehicles that are old or have a high mileage.

Symptoms of a failed Mercedes-Benz coolant pipe:

Leakage: Cracks may occur at the joints or body of a water pipe due to thermal expansion or contraction, causing coolant leakage and lowering heat dissipation efficiency.  

Joint sealing failure: The Bakelite joints connecting the water pipe to the auxiliary radiator and water pump have aged and deformed, or the sealing ring has hardened and lost its elasticity, thereby causing leakage.

Blockage: Impurities and sediment may accumulate in the coolant, causing pipeline blocking and affecting the normal operation of the cooling system.

Suggestions for daily maintenance of coolant pipe failures:

Regular inspection: Check the water pipe joints every 2 years or every 40,000 kilometers of mileage for any signs of crystallization or whitening (due to residual coolant evaporation).

Low quality of coolant: Prevent accelerated aging of Bakelite caused by inferior coolant.

Systematic replacement: If the vehicle is over 8 years old or has a mileage of over 100,000 kilometers, it is recommended that the water pipes, thermostats, and water pump should be all replaced as a general preventive measure.

vika stainless steel coolant pipes

Advantages of vika stainless steel coolant pipes:

Material: The body of vika stainless steel coolant pipes is made of 304 stainless steel, which leads to high strength and excellent resistance to high temperature, high pressure, and corrosion. The joint sealing rings are made of EPDM rubber, which is resistant to high temperature and high pressure, thus solving the problem of leakage of original Bakelite pipes after use for 5 years.

Process: All welding processes are realized with furnace welding technology, which leads to high welding strength and elegant welds without pores.

Factory test: All vika stainless steel coolant pipes receive 100% pressure testing before shipment to ensure full compliance with quality standards.
