Mokka Low Coolant

My 2018 Vauxhall Mokka, diesel engine, with 124492 km is throwing up a check engine light and codes indicate low coolant. Coolant is indeed low. No visible leaks around the radiator hoses, and the radiator cap seems fine. Could there be air pockets somewhere?

A 2018 Vauxhall Mokka with a diesel engine displayed a check engine light due to low coolant levels. Despite no visible leaks around the radiator hoses and a seemingly fine radiator cap, the coolant was low. A suggestion was made to check for air pockets, but ultimately, a workshop visit revealed a small leak in one of the radiator connections, which was resolved with a new clip and coolant top-up.

Did this summary help you solve your problem?

I had a similar issue with my Mokka. Check your coolant level first thing in the morning, before you start the engine. Is it consistently low, or does it fluctuate?

Good shout. I'll check it cold in the morning. But if it is consistently low, even when cold, what was the culprit in your case?

Mine was consistently low. I topped it up a couple of times, but it kept dropping. Ultimately, I took it to a workshop. They pressure tested the system and found a small leak in the water pump. Worth getting it checked out properly.

Thanks for the insight. Much appreciated. Took it to the shop and they found a small leak on one of the radiator connections. New clip and top up, 52€ all in. Sorted.
