Land Rover Repair: Range Rover 2004, coolant loss, coolant level


Question
I have two questions

1-Every time i start the car after 5 min of driving i hear three beeps with no message what can it be?

2-The dealer changed my complete engine 2000 miles ago. Since then I have been back four times to fix low engine coolant message.

the first time they said they did not bleed the system properly
the second time they said they did not top up the coolant level.
the third time they said i had a crack pipe and they changed it.
the fourth time they said while changing the pipe they must of forgot to bleed the system.

I told them that the engine is most likely to be burning the coolant as we have no signs of leakage and we were missing 2.5 liters.

What can it be?

Answer
I can't say anything about the beeping without knowing of a warning message that accompanies it.  I have never come across a beep without a warning light on these cars.  I can only make a good guess that it is the hood switch as this is quite common.

The problem with the coolant loss is probably either that they never have bled the system completely or your radiator has rotted out.  It is quite common on these cars to have the radiator go in as little as one year.  There was also an internal fault with the radiators, which was only recently rectified.  Either way, a faulty radiator causes the car to lose coolant very slowly, but steadily.  You lose the coolant, but not enough to see it under the car.
