Do not allow oil to spill onto or come into contact with hot exhaust pipe surfaces. NOTE Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please consult your Volvo retailer. 226 06 Maintenance and specifications Fluids Coolant Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified Volvo service technician. See page 279 for information on cooling system capacities. CAUTION Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of water and antifreeze). The cooling system must always be kept filled to the correct level, and the level must be between the MIN and MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage. Different types of antifreeze/coolant may not be mixed. Check coolant regularly. WARNING Never remove the radiator cap while the engine is warm. Wait until the vehicle cools. If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap slowly so that the overpressure dissipates. 227 06 Maintenance and specifications Fluids Brake fluid
