The cooler is there for a reason: to prevent the power steering fluid from overheating. Power steering fluid generates heat during operation. Without the cooler, the fluid will overheat, leading to:
* Fluid degradation: Overheating breaks down the fluid, reducing its lubricating properties and leading to premature wear of the power steering pump and components.
* Pump failure: The power steering pump is particularly vulnerable to heat damage. Overheating can cause it to seize, requiring a costly replacement.
* Reduced steering assist: Overheated fluid becomes less effective, resulting in stiff or difficult steering.
* Leaks: Heat can weaken seals and hoses, increasing the risk of leaks.
While it might seem like a simple solution to bypass the cooler, the long-term consequences are far more significant and expensive than simply keeping the cooler in place. If the cooler itself is damaged or leaking, it should be repaired or replaced, not bypassed.
