    2019 Discovery Td6 HSE Farallon Black

    over heating TD6

    Odd issue with my 2019 Discovery 5 TD6 today. My Disco5 has 144,000 kms on it and it was 6 Celius out today. after driving for 15 minutes a Red warning appeared on the dash- STOP SAFELY ENGINE OVER HEATING. The temperature gauge was in the red zone. i stopped and shut off the engine for about 5-8 minutes. i started the engine the temperature had dropped to about normal. After driving for 10 minutes same routine- overheated stopped again. i decided to head home and figure out what was going on. i had to stop 2 more times before reaching my home.

    The engine has no visible coolant leaks and the coolant level was not down at all. i connected my scanner and there was no engine codes. 30 minutes later i drove the Discovery for 40 minutes and the water temperature rose to its normal position and no more over heating. has anyone had a similar problem with the TD6 Land Rover?

    You could try bleeding the system, it might have been an airlock... loosening the bleed screw on top of the front cross-over pipe should let you know if there's air in the system.
