Coolant change.
I can't see a radiator drain plug so where is the best drain point? What is a good make of Anti-freeze and how much does the 2.4 require?
Thankyou. 2008 RS4 gone, 123d M Sport, and a Puma 90 XS..

Oh excuse my bad reading!
this is the bleed screw

there is no coolant drain plug in puma any more, the workshop manual says use the fuel cooler coolant pipe (lowest point) to drain and also remove the hose to the thermostat.

Caltex is Texaco Thumbs Up

For my Arctic trip I flushed and replaced the coolant

I also used the fuel cooler coolant connector to drain the radiator
I then flushed with water until it ran clear
Popped the lower connector on
Filled using Land Rover coolant which is texaco
I think it was a 65% mix - this is then good for -45c .. Any higher (more antifreeze) and it gives less protection

United Kingdom 2013 Defender 110 Puma 2.2 XS DCPU Keswick Green
Anti-freeze spec for the 2.4 is stated as WAS-M97B44-D.

Anti-freeze concentration - Will provide frost protection to -40°C (-40°F) 50%

Item Capacity
Cooling System 10 Liters (17.6 pints) (10.6 quarts)
Radiator 2.3 Liters (4 pints) (2.4 quarts)
Coolant Expansion Tank (To Cold Level) 1.2 Liters (2.1 pints) (1.3 quarts)

Workshop manual lists details as:

1. Set the heater controls to Hot.

2. WARNING: Since injury such as scalding could be caused by escaping steam or coolant, do not remove the filler cap from the coolant expansion tank while the system is hot. Remove the coolant expansion tank cap.

3. WARNING: Since injury such as scalding could be caused by escaping steam or coolant, do not remove the
cooling system bleed screw while the system is hot. Loosen the cooling system bleed screw.

4. WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety
stands. Raise and support the vehicle.

5. WARNING: Eye protection must be worn. Position a container to collect the coolant. Disconnect the 2 fuel cooler coolant pipes. Allow the coolant to drain.

6. WARNING: Eye protection must be worn. Disconnect the oil thermostat coolant hose. Allow the coolant to drain.

8. Connect the 2 fuel cooler coolant pipes.

9. Connect the oil thermostat coolant hose.

10. CAUTIONS: Engine coolant will damage the paint finished surfaces. If spilt, immediately remove the coolant and clean the area with water. Anti-freeze concentration must be maintained at 50%. Fill the cooling system expansion tank until the coolant level becomes static with in the "COLD FILL RANGE".

11. Tighten the cooling system bleed screw.

12. Install the coolant expansion tank cap.

13. CAUTIONS: Make sure the coolant level remains above the "COLD FILL RANGE" lower level mark. Observe the engine temperature gauge. If the engine starts to over-heat switch off immediately and allow to cool. Failure to follow this instruction may cause damage to the vehicle. Start and run the engine. Hold the engine speed at 3,000 RPM for one minute. Return the engine to idle for five minutes. Hold the engine speed at 3,000 RPM for one minute. Run the engine until the thermostat opens.

14. 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.

• NOTE: When the coolant bleed is complete and prior to installing the expansion tank cap, top-up the expansion tank to 30mm above the maximum level. Switch the engine off. Remove the coolant expansion cap, allow the level to settle and top-up so that the level is 30mm above the upper level. Allow the engine to cool.

15. Clean any spilt coolant from the vehicle.

16. Check and top-up the coolant if required.

Comma Glysantin G30, the red stuff. 5l is about £22. I've always found it readily available and good as an antifreeze and coolant.
