Ranger Coolant Loss

The error code is just 'Coolant Level Too Low'. The coolant drops about 200ml every 500 km. I checked the radiator and found nothing. Would a pressure test help find subtle leaks?

200ml every 500km is more than normal. A pressure test is a great idea. But with that rate of coolant loss and a generic code, I’d have a shop look at it. It could be internal, and you don't want to risk engine damage. Better safe than sorry with a diesel.

I took the Ranger to a workshop. The pressure test showed a leak in the thermostat housing. The repair was 52€. It wasn’t a head gasket, and your advice helped prevent further issues. Thanks for the input.

Low coolant is never good. I had a similar thing with my old truck and a check engine light. Have you checked the radiator for leaks? What does the error code say specifically? How quickly is the coolant dropping?
