**Why You Should Never Mix PG55 RC with Other Coolants or Tap Water**
### Introduction
When it comes to high-performance cooling, PG55 RC stands as the premier choice for motorsports and enthusiasts who demand the best. However, to unlock its full potential, one crucial rule must be followed: **Never mix PG55 RC with other coolants or tap water**. Doing so can reduce its effectiveness, compromise engine protection, and even damage your cooling system. In this article, we will break down why a **full coolant flush** is essential when switching to PG55 RC and the risks of mixing it with other substances.

### 1. The Science Behind PG55 RC’s Performance
PG55 RC is engineered with a **golden ratio (55:45) of propylene glycol and purified water**, optimized for motorsports and high-performance applications. This precise balance ensures:
- **Superior heat transfer** for consistent cooling under extreme conditions.
- **Enhanced corrosion protection**, safeguarding both aluminum and cast iron components.
- **Long-lasting performance**, reducing wear and buildup over time.
Mixing PG55 RC with another coolant or diluting it with tap water disrupts this carefully optimized ratio, leading to **inefficient cooling** and **reduced thermal stability**.

### 2. Chemical Reactions: Why Mixing Coolants is Dangerous
PG55 RC is formulated with **OAT (Organic Acid Technology)**, which is free from nitrites, phosphates, and amines—common additives in traditional coolants. Mixing PG55 RC with other coolants can cause **unwanted chemical reactions**, resulting in:
- **Sludge and deposits** forming inside the radiator and cooling passages.
- **Reduced corrosion resistance**, leading to premature wear of engine components.
- **Clogged coolant passages**, which can cause overheating and system failure.
To ensure **maximum protection and longevity**, PG55 RC must be used exclusively in a **clean system** free of any old coolant residues.

### 3. The Hidden Dangers of Tap Water
Many assume that diluting coolant with tap water is harmless, but this can have serious consequences. Tap water contains minerals, chlorine, and impurities that cause:
- **Scale buildup**, which reduces cooling efficiency and restricts coolant flow.
- **Electrolysis and corrosion**, damaging aluminum radiators and engine blocks.
- **pH imbalance**, which accelerates chemical degradation of coolant additives.
PG55 RC is formulated with **high-precision filtered water** to eliminate these risks. By introducing tap water, you compromise the engineered purity that makes PG55 RC so effective.

### 4. The Importance of a Full Coolant Flush
To experience the full benefits of PG55 RC, a **complete coolant system flush** is required before switching. Even a **small amount of old coolant or tap water** left in the system can alter its composition and reduce its effectiveness.
#### **How to Properly Flush Your Cooling System:**
1. **Drain the old coolant completely**, including from the radiator, engine block, and heater core.
2. **Flush the system with distilled water** to remove any remaining contaminants.
3. **Repeat the flushing process** until all traces of old coolant are gone.
4. **Refill the system with PG55 RC** to maintain its optimal formulation.
5. **Bleed the cooling system** to remove air pockets and ensure proper circulation.
Following these steps guarantees that PG55 RC functions at **peak efficiency**, providing **maximum cooling performance and protection**.

### 5. Key Takeaways: What You Should Remember
✅ **Do not mix PG55 RC with other coolants** – it can cause sludge, deposits, and reduced protection. I can say the same thing: **do not mix different coolants**. Any coolant has its own aims. Our coolant, **PG55 series, has special reasons for each**.
✅ **Do not dilute with tap water** – it introduces impurities that damage the cooling system.
✅ **Always perform a full flush** before switching to PG55 RC for maximum effectiveness.
By following these guidelines, you ensure that PG55 RC delivers **exceptional cooling performance**, keeping your engine running at its best.

### Final Thoughts
PG55 RC is trusted by **Super GT, D1GP, and high-performance JDM vehicles** for a reason. Its **advanced formulation, premium purity, and racing pedigree** make it the best choice for serious drivers. However, to get the most out of it, proper installation is a must. **A full coolant flush is not optional—it’s essential.**
Upgrade your cooling system today with **PG55 RC**, and experience the difference that true high-performance engineering makes.
