Part Number
: K-4245
Condition: New
Manufacture/Brand: Eaton

Fits K-4245 For Freightliner, Kenworth, Peterbilt, International (Navistar), Mack, Commercial buses, Fleet vehicles with Bendix air systems

    Purpose of using K-4245:

    1. Prevent overheating

    • Keeps engines, machines, and systems from getting too hot
    • Example: a radiator cooling an engine

    2. Improve efficiency

    • Reuses heat instead of wasting it
    • Saves fuel, energy, and operating costs

    3. Control temperature precisely

    • Maintains stable operating conditions
    • Important for performance and safety

    4. Protect components

    • Reduces wear and damage caused by excessive heat
    • Extends equipment life

    5. Enable heating or cooling

    • Can either remove heat (cooling) or transfer it for use (heating)

     

    Signs of a Bad Heat Enchange: K-4245:

    1. Overheating

    • Engine or system runs hotter than normal
    • Temperature gauge climbs quickly
    • Heat exchanger isn’t removing heat effectively

    2. Fluid leaks

    • Coolant, oil, or other fluid leaking from the unit
    • Visible drips, puddles, or residue
    • Often caused by cracks or corrosion

    3. Fluid contamination (mixing fluids)

    • Oil looks milky or foamy
    • Coolant appears dirty or oily
    • Means internal walls may be damaged and fluids are mixing (serious issue)

    4. Reduced performance

    • Engine loses efficiency or power
    • HVAC system doesn’t heat/cool properly
    • Heat isn’t transferring like it should

    5. Unusual smells

    • Sweet smell (coolant leak)
    • Burning smell (overheating fluid or components)

    6. Visible corrosion or buildup

    • Rust, scale, or debris on or inside the exchanger
    • Blocks heat transfer and reduces efficiency

    7. Pressure or flow issues

    • Low coolant flow or restricted lines
    • System pressure fluctuates abnormally
