    OAT - Leyland Hose & Silicone Services
    An OAT (Organic Acid Technology) Antifreeze Coolant Hose is a specialized coolant hose designed to withstand the harsh chemical properties (like high pH and ethyl-hexanoic acids) of modern OAT coolants, which standard rubber or even some silicone hoses struggle with, offering superior durability, burst resistance, and long life for engines using these advanced coolants. These hoses, often made from reinforced silicone with special liners, ensure proper engine cooling without degrading from aggressive coolant additives, a common issue with older hose types. 
    Why You Need OAT Compatible Hoses 
    • OAT Coolant Chemistry: OAT coolants use organic acids for corrosion protection, unlike older inorganic formulations.
    • Chemical Aggression: The high pH and acids in OAT coolants can prematurely degrade standard EPDM rubber or even fluoro-lined silicone hoses, leading to swelling, cracking, and failure.
    • Superior Material: OAT-grade hoses (often high-grade silicone or specialized materials) resist these chemicals, offering excellent compatibility and preventing failure points. 
    Key Features of OAT Coolant Hoses 
    • High Temperature & Pressure: Handle extreme engine bay temperatures and boast higher burst pressures than standard hoses.
    • Longer Life: Provide extended service life, matching the extended intervals of OAT coolants.
    • Material: Typically silicone-based with enhanced liners for chemical resistance. 
    When to Use Them 
    • When your vehicle uses an OAT or HOAT (Hybrid OAT) coolant, common in many modern cars.
    • For high-performance applications or in areas with high under-hood temperatures.
    • As a replacement for failing standard hoses in vehicles with OAT coolant.

    AI Overview
    Can You Mix Different Engine Coolants? Risks, Safety Tips & Guide
    Mixing OAT (Organic Acid Technology) coolant with regular (often IAT - Inorganic Acid Technology) coolant is a bad idea; it can cause the corrosion inhibitors to fail, creating sludge, gelling, and a thick paste that clogs the cooling system, leading to overheating, water pump damage, and costly repairs, even if it doesn't gel immediately. Always use the exact coolant type specified in your owner's manual, as mixing can ruin the protective properties, compromise engine performance, and potentially cause severe component failure.
     
    This video explains the symptoms of using the wrong coolant in your car:

    YouTube · Feb 8, 2024
    Why It's a Problem
    • Incompatible Additives:
      OAT coolants use different chemicals than traditional coolants; mixing them disrupts the chemical balance. 
    • Corrosion Inhibitor Failure:
      The mixture loses its ability to protect against rust and corrosion, leading to metal component damage. 
    • Sludge & Gelling:
      The most common and damaging result is the formation of a thick, gelatinous sludge that blocks narrow passages in the radiator and heater core. 
    Consequences of Mixing 
    • Overheating: Clogged passages prevent proper heat transfer.
    • Component Damage: Water pump failure, damaged radiator, and corroded cylinder heads.
    • Expensive Repairs: Flushing the system and replacing parts can cost thousands.
    What to Do If You Mixed Them
    1. Don't Drive Extensively: Avoid driving to prevent immediate damage. 
    2. Drain & Flush Immediately: The only safe solution is a complete system flush with distilled water and a proper flushing agent, then refilling with the correct OAT coolant. 
    3. Consult a Professional: If you're unsure, have a mechanic inspect and flush the system. 
    Key Takeaway: Never mix OAT with conventional coolants; use only the type specified by your vehicle's manufacturer for optimal engine health, according to manufacturers and experts.

      OATs were the next coolant solution that made up for the shortcomings of IATs. These coolants use organic acids and corrosion inhibitors and therefore, have extended service life. Furthermore, these extended life coolants can last up to 5 years or 240,000 km.

      AI Overview
      Ask The NAPA Experts: What Is OAT Coolant? » NAPA Blog
      OAT (Organic Acid Technology) coolant is a long-life formula for modern vehicles, especially GM, Chrysler, Ford, European, and Asian cars, using organic acids for protection and often featuring an orange color (like GM Dexcool or Zerex American Vehicle). Compatible OAT coolants can be mixed for top-offs (like Prestone Extended Life, Peak Global or Shell Rotella Ultra ELC), but never mix OAT with older traditional green IAT coolants; check your owner's manual for specific color and type (OAT, HOAT, P-OAT) for best results.
       
      Common OAT Coolant Brands & Types:
      • Orange OAT:
        GM Dex-Cool, Zerex American Vehicle, Peak Original Equipment Technology (OET) Orange. 
      • Nitrite-Free OAT (NOAT/ELC):
        Prestone Command Nitrite Free ELC and Guardol OAT HD for heavy-duty diesel, Shell Rotella Ultra ELC. 
      • P-OAT (Phosphated OAT):
        Newer yellow coolants like Ford's yellow P-OAT are often backwards compatible with orange OAT but not older coolants. 
      Key Compatibility Rules:
      • Stick to Your Color: Orange OAT with Orange OAT; Yellow P-OAT with Yellow P-OAT. 
      • Avoid Mixing Old & New: OAT won't mix well with old green (IAT) or gold coolants. 
      • Check the Label: Look for "OAT," "Extended Life," "Nitrite-Free," "Silicate & Phosphate Free". 
      • When in doubt, flush: For best performance with newer OAT/P-OAT, perform a full system flush before filling.
