V90 Coolant Loss

My 2022 Volvo V90, gasoline engine, is acting up. The check engine light is on, and the error memory says the coolant is low. I checked, and it is. I haven't seen any driveway leaks. Could this be a fluke, or is it a sign of something bigger, like engine overheating?

Low coolant in a modern engine is always a concern. At 157169 km, a small leak could evaporate before hitting the ground. Check around the radiator hoses and the radiator for dried coolant. Is the cooling fan running excessively after you shut off the car?

Thanks! I did a quick visual check of the hoses but didn't see anything obvious. The fan does seem to run longer than I remember after parking. Could air pockets in the cooling system cause this, even without a leak?

Air pockets can cause the fan to run longer, but they usually develop because coolant is low. Given the symptoms and mileage, a cooling system pressure test is advisable. It's best to have a workshop check for leaks before it leads to engine damage.

Okay, that makes sense. I appreciate the advice! I took it to my local shop, and they found a very small leak in one of the radiator hoses. They replaced the hose, topped off the coolant, and pressure tested everything. It cost me 52€, but at least it's sorted. Thanks again!
