* Overheating: If the engine is overheating, the air conditioner can cause it to overheat even further, leading to smoke coming from the engine compartment.
* Coolant leak: A leak in the coolant system can cause the coolant to drip onto the engine, where it can vaporize and create smoke.
* Oil leak: A leak in the oil system can also cause oil to drip onto the engine, where it can vaporize and create smoke.
* Faulty compressor: A faulty air conditioning compressor can cause the system to malfunction, leading to smoke coming from the engine compartment.
If you see smoke coming from your Volvo 850 when you turn on the air conditioner, it is important to take it to a mechanic to have it diagnosed as soon as possible.
