Imported cooling system solutions and maintenance
Sponsored by CRP Automotive, the company brings you REIN cars
Have you noticed that many European cars and SUVs no longer have the coolant replacement intervals listed in the service information? This may be because the cooling system needs to be repaired or replaced before this interval. It can be a hose, a plastic connector or a water pump. Your store has options. Some replacement parts may be better than original parts. When dealing with the complexity and longevity of today's vehicles, these parts can create a win-win situation for your store and customers.
These solutions can simplify maintenance and prevent future failures. In a 45-minute webinar sponsored by CRP Automotive, the company that brought you Rein Automotive, we will introduce six common cooling system repairs for BMW, Audi and Volkswagen. These repair solutions will cover more than 6 million cars on the road today.

It is important to understand the type of power steering hose before replacement.
The first part of any power steering inspection should be checking the fluid. If the fluid is gray or black, it may indicate that the inner layer of the hose has been worn, degraded, or damaged by incorrect fluid. This type of discoloration is caused by rubber or metal particles in the fluid.
There are two main categories of power steering hoses: high pressure and low pressure. The high-pressure power steering hose can have up to five layers and can withstand pressures up to 1,500 psi. The inner layer can resist fluids and seal it to prevent penetration into the outer layer.
The next inner layer is designed to give the hose strength to resist high pressure. These layers can be made of high-tech polymer materials and fabrics. The outer layer of these power steering hoses is designed to protect the inner layer from wear, chemicals and heat.
The low-pressure power steering hose is designed with fewer layers and bears less pressure. However, they must have the same resistance to the elements in the engine compartment.
The high-pressure power steering hose assembly should use hoses that meet or exceed SAE J2050. This standard test is rigorous testing of power steering hoses and accessories at 40 to 150 °C (-40 to 302 °F) and a maximum working pressure of 1,500 psi. The low pressure/return hose should be of SAE J189 or J188. This type of hose must withstand the same temperature range as SAE 2050 hose, but only has been tested at 250 psi.
If you replace the high-pressure hose, it is strongly recommended to replace the low-pressure hose at the same time.
The life of the power steering hose is not easy. The power steering hose must withstand some of the highest pressures and temperatures under the hood. Coupled with the erosion of the outer layer of these components by ozone, oil and solvents, it is easy to see why some hoses fail.
Power steering fluid may be flammable. When it ignites, it is difficult to extinguish. It is very important to check the pipeline. Any leaks should not be taken lightly, because loss of power steering can cause accidents.
As we discussed before, a key part of any power steering inspection is the fluid inspection. Discolored fluid may indicate that the inner layer of the hose has been severely degraded by rubber or metal particles in the fluid.
High temperature pulsation will cause the power steering hose to age from the inside. Continuous bending and pressure fluctuations can cause small particles in the hose to rupture, which can pass through the system and cause system failure.
When inspecting the power steering hose, check carefully for the following signs on the outside:
Wear and tear: If there is any physical damage to the outer layer of the power steering hose, it should be carefully inspected. If the outer layer is damaged, the inner layer of the hose may be exposed to harmful chemicals, heat, and ozone. If the power steering hose is damaged, investigate how it is damaged. Worn motor mounts, missing mounting tabs, and leaking exhaust gaskets can damage the power steering hose.
Bulge: Any bulge on the power steering hose indicates that the inner layer has failed, and the fluid working between the layers is about to fail completely.
Softness: If the hose feels soft in a certain area, it means that the inner or outer layer is cracking.
Cracking and peeling: If the outer layer of the power steering hose is cracked or peeled, this is an early sign of internal wear and the hose has lost its ability to absorb pressure fluctuations.
Corrosion: Extreme corrosion on fittings can cause failure of the power steering hose assembly. Most accessories are covered with corrosion-resistant coatings and electroplating methods. If they are removed due to wear, solvents, or other processes, the joint will eventually fail.
Leakage: The power steering fluid will not magically disappear. Any leakage in the hose assembly is a problem that should be resolved.
Be sure to use the correct fasteners. Low pressure or return lines are usually fixed with constant tension hose clamps or spring clamps. When the hose material is compressed, the use of worm-driven clamps may cause leakage. The return hose may have to be connected from the rack to the reservoir. The wiring of the hose is not accidental; this is why many original equipment manufacturers use molded hose assemblies.
Due to corrosion, it may be difficult to remove high-pressure pipelines on high mileage vehicles. Banjo accessories may get stuck around the bolts. When you try to loosen the bolt, it will break. In addition, some inverted flared fittings may jam the pipeline and twist the pipeline like toffee. If you have difficulty with any type of joints, try immersing them in penetrating fluid before trying to place a wrench on them.
