Engine oil level
• Make sure that the car is on level ground.
• Check the oil level with the engine at operating temperature, and between 2 and 5 minutes after the engine has been switched off.
If the oil is checked immediately after driving the vehicle, some of the oil will remain in the upper engine components, resulting in an inaccurate reading on the dipstick.
The correct oil
Modern engines place great demands on their oil. It is very important that the correct oil for your car is used.
|Engine oil grade
||Multigrade engine oil, viscosity SAE 0W-30
• If you have to add oil frequently, you should check whether you have any oil leaks. Place some clean paper under the car overnight, and check for stains in the morning. If there are no leaks, then the engine may be burning oil.
• Always maintain the level between the upper and lower dipstick marks (see photo 3). If the level is too low, severe engine damage may occur. Oil seal failure may result if the engine is overfilled by adding too much oil.
On most models, the dipstick is located on the front of the engine (see Underbonnet check points for exact location). On models with no dipstick the oil level can be checked by turning the ignition on and scrolling through the information display until the oil level is shown. Withdraw the dipstick.
Using a clean rag or paper towel remove all oil from the dipstick. Insert the clean dipstick into the tube and then withdraw it again.
Note the oil level on the end of the dipstick (XC60 model shown) which should be between the upper mark (B) and lower mark (A). Approximately 1.0 litre of oil will raise the level from the lower mark to the upper mark.
Oil is added through the filler cap hole. Unscrew the cap and withdraw it. Top-up the level. A funnel may help to reduce spillage. Add the oil slowly, checking the level on the dipstick often. Do not overfill. Refit the cap on completion.

Do not attempt to remove the expansion tank pressure cap when the engine is hot, as there is a very great risk of scalding. Do not leave open containers of coolant about, as it is poisonous.
• With a sealed-type cooling system, adding coolant should not be necessary on a regular basis. If frequent topping-up is required, it is likely there is a leak. Check the radiator, all hoses and joint faces for signs of staining or wetness, and rectify as necessary.
• It is important that antifreeze is used in the cooling system all year round, not just during the winter months. Don’t top up with water alone, as the antifreeze will become diluted.
The coolant level varies with the temperature of the engine. When the engine is cold, the coolant level should be between the MIN/MAX marks on the side of the tank (XC90 shown). When the engine is hot, the level will rise.
If topping-up is necessary, wait until the engine is cold. Slowly unscrew the expansion tank cap, to release any pressure present in the cooling system, and remove it.
Top-up the level by adding a mixture of water and antifreeze to the expansion tank. A funnel may help to reduce spillage. Refit the cap and tighten it securely.

Brake (and clutch) fluid level
On manual transmission models, the fluid reservoir also supplies the clutch master cylinder with fluid.
Before you start
• Make sure that your car is on level ground.
• Cleanliness is of great importance when dealing with the braking system, so take care to clean around the reservoir cap before topping-up. Use only clean brake fluid.
• If the reservoir requires repeated topping-up, this is an indication of a fluid leak somewhere in the system, which should be investigated immediately. Note that the level will drop naturally as the brake pad linings wear, but must never be allowed to fall below the MIN mark.
• If a leak is suspected, the car should not be driven until the braking system has been checked. Never take any risks where brakes are concerned.
Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it. Do not use fluid which has been standing open for some time, as it absorbs moisture from the air, which can cause a dangerous loss of braking effectiveness.
The MIN and MAX marks are indicated on the front of the reservoir located in the right-hand rear corner of the engine compartment. The fluid level must always be kept between the marks.
On XC60 models remove the cover to check the fluid level. The MAX mark is visible with the filler cap removed.
If topping-up is necessary, first wipe clean the area around the filler cap to prevent dirt entering the hydraulic system. Unscrew the cap and place it on an absorbent rag.
Carefully add fluid, taking care not to spill it onto the surrounding components. Use only DOT 4 fluid; mixing different types can cause damage to the system. After topping-up to the correct level, securely refit the cap and wipe off any spilt fluid.
Power steering fluid level
• Park the car on level ground.
• Set the steering wheel straight-ahead.
• The engine should be cold and turned off.
For the check to be accurate, the steering must not be turned while the level is being checked.
• The need for frequent topping-up indicates a leak, which should be investigated immediately.
The MAX and MIN marks are shown on the reservoir on XC60 models.
On XC90 models the reservoir filler cap incorporates a dipstick.
If topping up is necessary, wipe around the filler cap, remove the cap and top up with Volvo power steering fluid M2C204-A.
Washer fluid level
• Screenwash additives not only keep the windscreen clean during bad weather, they also prevent the washer system freezing in cold weather – which is when you are likely to need it most. Don’t top-up using plain water, as the screenwash will become diluted, and will freeze in cold weather.
• Check the operation of the windscreen and rear window washers. Adjust the nozzles using a pin if necessary, aiming the spray to a point slightly above the centre of the swept area.
On no account use engine coolant antifreeze in the screen washer system – this may damage the paintwork.
The reservoir for the windscreen and rear window washer systems is located on the front left-hand corner of the engine compartment on XC60 models and on the front right-hand side on XC90 models. If topping-up is necessary, open the cap.
When topping-up the reservoir a screenwash additive should be added in the quantities recommended on the bottle.
It could also be time to replace the wiper blades. For details, click below
Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. For maximum clarity of vision, wiper blades should be renewed annually.
Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. For maximum clarity of vision, wiper blades should be renewed annually, as a matter of course.
To remove a windscreen wiper blade, pull the arm fully away from the screen until it locks. Swivel the blade through 90°, then lift it off the wiper arm. Fit the new blade using a reversal of the removal procedure. Don’t forget to check the tailgate wiper blade as well.
