BMW Spray Pipe OE Code Number 61667275175 System Analysis
Spray pipe material and structure
★ Main Material
Spray hose OE code No. 61667202027 is mostly made of cold-resistant rubber or silicone, and some high-end models use reinforced nylon bellows, which is anti-aging and low-temperature-resistant (can be adapted to the environment from -30℃ to 80℃). The interface is often made of ABS engineering plastics.
ABS engineering plastic is commonly used at the interface, which is connected to the water nozzle and reservoir through clips or threads to ensure the sealing.
Key Component Design
★ Water spray nozzle:
Adopting precision injection molding process, the nozzle hole diameter is about 0.5-1mm to ensure even spraying of water mist.
Some models (e.g. BMW 5 Series GT) have built-in filters in the nozzles to prevent clogging by impurities.
★ Connecting piping:
The piping is divided into the main water supply pipe and branch piping, which is shunted to multiple nozzles through Y-type tee fittings.
Second, the common faults and maintenance
★ Failure phenomenon Cause Analysis Solution
Small amount of water spray / cut off The pipeline aging rupture, loose interfaces Replace the damaged pipe section, with waterproof tape to strengthen the connection.
Nozzle clogging Scale or foreign matter deposits Fine steel wire to dredge the nozzle, high-pressure air gun reverse flushing.
Glass water freezes and expands, cracking pipes Replace antifreeze glass water and check pipe sealing.
Maintenance Recommendations
★ Glass water selection
Avoid adding tap water directly, we recommend using the original antifreeze glass water (containing surfactant and antifreeze) to reduce scale generation.
Concentrated glass water should be diluted by 1:50 ratio to prevent high concentration corrosion of pipes.
★ Regular Inspection
Every six months, check whether the spray hose connections are loose, focusing on the bellows at the hood opening and closing (prone to cracking due to repeated bending).
Test the water spray system before winter to eliminate potential freezing risks in advance.
Modification and Upgrading
Silicone pipe alternative: the retrofit market offers high temperature resistant silicone spray pipe OE code number 61667205117, with 30% higher compressive strength, suitable for performance car users.
Quick maintenance accessories: universal Y-type tee connector, spiral connecting pipe and other accessories can simplify the maintenance process.
