Cooling System Concentration Check (G2647664): Check

WARNING: This page is about a different car, the 2023 Jaguar F-Pace and 2022 Jaguar F-Pace. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • The engine cooling system must be maintained with the correct concentration and type of engine coolant solution to prevent corrosion and frost damage.
  • Engine coolant will damage the paint finished surfaces. If spilled, immediately remove the coolant and clean the area with water.
  • Never remove the coolant expansion tank cap under any circumstances while the engine is operating.
NOTE:
  • This procedure contains some variation in the illustrations depending on the vehicle specification, but the essential information is always correct.
  • This procedure contains illustrations showing certain components removed to provide extra clarity.

  8. G15620646Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Clean the prism surface with a soft cloth.

  9. WARNING:
    • Release the cooling system pressure by slowly turning the coolant expansion tank cap a quarter of a turn. Cover the expansion tank cap with a thick cloth to prevent the possibility of scalding. Failure to follow this instruction may result in personal injury.
    • Since injury such as scalding could be caused by escaping steam or coolant, make sure the vehicle cooling system is cool prior to carrying out this procedure.
    CAUTION: Be prepared to collect escaping coolant.

    Remove the coolant expansion tank cap.

  10. G15620648Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Use the pipette to extract a coolant sample.

  11. G15620649Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Raise the cover plate.

  12. G15620650Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Put 2 drops of coolant on the prism surface.

  13. G15620651Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Lower the cover plate.

  14. NOTE: 50% coolant concentration mix provides a freeze point of -37°C.
    G15620652Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Observe the shadow line on the scale.

  15. G15620653Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Raise the cover plate.

  16. G15620654Courtesy of JAGUAR LAND ROVER NORTH AMERICA, LLC

    Clean the prism surface with a soft cloth.

    • If the coolant concentration mix is at 50%, proceed to Step  20.
    • If the coolant concentration mix is below 50%, proceed to Step 18.
    • If the coolant concentration mix is below 50%, proceed to Step  19.
  18. NOTE: Coolant concentration mix % must divided by 100. 50% would be calculated as 0.5.
    • If the coolant concentration mix is below 50%, the following calculation steps must be followed.
    • Step 1. Multiply the required coolant concentration mix % by the cooling system capacity.
    • Step 2. Multiply the current coolant concentration mix % by the cooling system capacity.
    • Step 3. Subtract the total of step 1 by total of step 2.
    • Step 4. Subtract the current coolant concentration mix % from 1.
    • Step 5. Divide the total of step 3 by the total of step 4.
    • Drain the coolant quantity given by the calculations and replace with concentrated antifreeze.
    • Proceed to Step  20.
  19. NOTE: Coolant concentration mix % must divided by 100. 50% would be calculated as 0.5.
    • If the coolant concentration mix is above 50%, the following calculation steps must be followed.
    • Step 1. Multiply the current coolant concentration mix % by the cooling system capacity.
    • Step 2. Multiply the required coolant concentration mix % by the cooling system capacity.
    • Step 3. Subtract the total of step 1 by total of step 2.
    • Step 4. Divide the total of step 3 by the current coolant concentration mix %.
    • Drain the coolant quantity given by the calculations and replace with distilled water.
  20. NOTE: Correct installation of the coolant expansion tank cap can be obtained by tightening the cap until 3 audible clicks are heard.

    Install the coolant expansion tank pressure cap.
