XC60 Coolant Loss
Summary of the thread
The 2014 Volvo XC60 is experiencing coolant loss, indicated by a check engine light and low coolant levels. Possible causes include leaks in the radiator hoses, malfunctioning cooling fan assembly, or air pockets in the system. The suggested solution is to inspect these components, and ultimately, a small leak in a radiator hose was identified and repaired, resolving the issue.

Radiator hoses and cooling fan, huh? Okay, I can take a look. But what about air pockets? I've heard those can cause problems with coolant levels too. And how would I even check the cooling fan assembly? Like, is there a specific way to tell if it's working properly?

Indeed, the presence of air pockets can introduce complexities to the diagnostic process, akin to an embolism within the aforementioned circulatory analogy. Air pockets disrupt the proper circulation of radiator fluid, leading to localized overheating and subsequent fluid expulsion. However, given your vehicle's age and the recurring nature of the issue, I am inclined to suspect a more tangible defect within the cooling architecture. Regarding the cooling fan, observe its operation subsequent to attaining normal operating temperature. It should cycle on and off as required to maintain thermal equilibrium. Given your stated level of mechanical experience, I would suggest a thorough evaluation by a qualified technician be conducted.

Alright, thanks for the advice! I think you're right, it's probably best to just take it in. It was a small leak in one of the radiator hoses. Got it fixed for 52€, so not too bad! Thanks again for pointing me in the right direction.

Greetings. A similar situation occurred with my previous vehicle, a 2012 Audi A4. Intermittent coolant loss, check engine light illuminated. The underlying cause eluded immediate detection. The cooling system, much like a circulatory system within the human body, is comprised of numerous interconnected components. Have you inspected the radiator hoses for any evidence of fissures or compromise? Furthermore, is the cooling fan assembly operating as designed? Insufficient operation can induce elevated temperatures and subsequent fluid loss through the coolant reservoir's pressure relief valve.
