Engine oil level

1 • Make sure that your car is on level ground.
2 • Check the oil level before the car is driven, or at least 5 minutes after the engine has been switched off.
HINT: 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

3 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 5W/30 to ACEA B1/B3 Land Rover specification WSS-M2C-913B

Car care

4 • 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, the engine may be burning oil, or the oil may only be leaking when the engine is running.
5 • 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.
The dipstick top is often brightly-coloured for easy identification (see Underbonnet check points for exact location). Withdraw the dipstick.
Using a clean rag or paper towel remove all oil from the dipstick. Insert the clean dipstick into the tube as far as it will go, then withdraw it again.
Note the oil level on the end of the dipstick, which should be between the upper full mark (1) and low minimum mark(2). Approximately 1.75 litres of oil will raise the level from the lower mark to the upper mark.
Oil is added through the filler cap. Unscrew the cap and top-up the level; a funnel may help to reduce spillage.
Add the oil slowly, checking the level on the dipstick often. Don’t overfill (see Car care). If you need to renew the oil and filter, click below

Engine oil and filter change

HINT: Frequent oil and filterchanges are the mostimportant preventativemaintenance proceduresthat can be undertaken by the DIYowner. As engine oil ages, it becomesdiluted and contaminated, which leadsto premature engine wear.
1 Before starting this procedure, gather together all the necessary tools and materials. Also make sure that you have plenty of clean rags and newspapers handy, to mop-up any spills. Ideally, the engine oil should be warm, as it will drain better, and more built-up sludge will be removed with it. Take care, however, not to touch the exhaust or any other hot parts of the engine when working under the vehicle. To avoid any possibility of scalding, and to protect yourself from possible skin irritants and other harmful contaminants in used engine oils, it is advisable to wear rubber gloves when carrying out this work.
2 Access to the underside of the vehicle will be greatly improved if it can be raised on a lift, driven onto ramps, or jacked up and supported on axle stands. Whichever method is chosen, make sure that the vehicle remains as level as possible, to enable the oil to drain fully.
3 Remove the engine oil filler cap, then pull the cover upwards from the top of the engine to release the rubber mountings (see illustration)
Pull the engine cover upwards
4 Clean the area around the filter cover, then use a socket to unscrew the filter cover 4 complete revolutions to allow the oil to drain (see illustrations) .

Renew the O-ring seal (arrowed)
6 Working underneath the vehicle, undo the retaining bolts and remove the engine undershield (see illustration) . Note the locations of the various washers. Take care as the undershield is surprisingly heavy.

7 Clean the drain plug and the area around it, then slacken it using a suitable socket or spanner (see illustration) . If possible, try to keep the plug pressed into the sump while unscrewing it by hand the last couple of turns. As the plug releases from the threads, move it away sharply, so that the stream of oil issuing from the sump runs into the container, not up your sleeve.

8 Allow some time for the old oil to drain, noting that it may be necessary to reposition the container as the oil flow slows to a trickle.
9 After all the oil has drained, wipe off the drain plug with a clean rag, and discard the seal – a new seal must be fitted (see illustration) . Clean the area around the drain plug opening, then fit the seal and tighten the plug to 25 Nm (18 Ibf ft).
Note: Note that on some vehicles, the seal is integral with the plug. Consequently, a new plug must be fitted.
Renew the drain plug seal (arrowed)
10 Insert the new filter element, ensuring the spigot aligns with the corresponding hole in the filter housing (see illustration) .
Align the filter spigot with the hole in the filter housing (arrowed)
11 Renew the filter cover O-ring seal, lubricate the seal with clean engine oil, then refit the cover and tighten it to 25 Nm (18 Ibf ft) (see illustration) .
Lubricate the filter cover O-ring seal
12 Fill the engine with the specified quantity and grade of oil. Pour the oil in slowly, otherwise it may overflow. Check that the oil level is up to the correct level on the dipstick, then refit and tighten the oil filler cap.
Engine oil quantity 5.5 litres
Difference between upper and lower dipstick markings 1.75 litres
Engine oil grade Multigrade engine oil, viscosity SAE 5W/30 to ACEA B1/B3 Land Rover specification WSS-M2C-913B
13 Remove the old oil and all tools from under the vehicle, then refit the engine undershield and lower the vehicle to the ground.
14 Refit the engine top cover.
15 Run the engine for a few minutes, and check that there are no leaks.
16 Switch off the engine, and wait a few minutes for the oil to settle in the sump once more. With the new oil circulated and the filter now completely full, recheck the level on the dipstick, and add more oil if necessary.
17 Dispose of the used engine oil responsibly.

Coolant level

Warning: 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.

Car care

6 • 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.
7 • 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 too diluted.
Antifreeze grade Ethylene glycol based antifreeze with OATS corrosion inhibitors
The coolant level is indicated by a fill level line on the side of the expansion tank on the left-hand side of the engine compartment.
If topping-up is necessary, wait until the engine is cold. Slowly remove the expansion tank cap to release any pressure present in the cooling system, and remove it.
Add a mixture of water and antifreeze to the expansion tank until the surface of the coolant is level with the mark on the expansion tank. Refit the cap securely. Should you need to replace the coolant, click below

Coolant replacement

Draining

Warning: Wait until the engine is cold before starting this procedure. Do not allow antifreeze to come in contact with your skin, or with the painted surfaces of the vehicle. Rinse off spills immediately with plenty of water. Never leave antifreeze lying around in an open container, or in a puddle in the driveway or garage floor. Children and pets are attracted by its sweet smell, but antifreeze is fatal if ingested.
1 Raise the front of the vehicle and support it securely on axle stands.
2 Set the heater controls to maximum heater output.
3 Undo the oil filler cap, then pull the plastic cover upwards from the top of the engine (see illustration) .
Pull the engine cover upwards
4 Cover the expansion tank with a wad of rag, and slowly turn the cap anti-clockwise to relieve any pressure in the cooling system (a hissing sound will normally be heard). Wait until any pressure remaining in the system is released, then continue to turn the cap until it can be removed.
5 Undo the 4 bolts and remove the access panel beneath the radiator (see illustration) .

6 Position a suitable container beneath the thermostat housing. Release the retaining clip, then disconnect the radiator lower coolant hose from the thermostat housing and allow the coolant to drain into the container (see illustration) .
Working underneath, release the clamp and disconnect the radiator hose from the thermostat housing (arrowed)
7 Once the coolant has stopped draining, reconnect the hose and secure it with the clip.

Models with auxiliary (rear) heating system

8 Remove the spare wheel from under the rear of the vehicle.
9 Position a suitable container beneath the rear heater coolant hoses. Release the retaining clips, then disconnect the hoses and allow the coolant to drain into the container.
10 Once the coolant has stopped draining, reconnect the hoses and secure them with the clips.

Filling

11 Before attempting to fill the cooling system, make sure that all hoses and clips are in good condition, and that the clips are tight. Note that an antifreeze mixture must be used all year round, to prevent corrosion of the alloy engine components.
Coolant quantity:
  With rear passenger compartment heating:
    With fuel burning heater 13.1 litres
    Without fuel burning heater 12.1 litres
  Without rear compartment heating:
    With fuel burning heater 10.3 litres
  Without fuel burning heater 9.4 litres
Antifreeze type Ethylene glycol based antifreeze with OATS corrosion inhibitors
12 Slacken the bleed screw in the top of the coolant expansion tank, and the bleed screw in front of the left-hand cylinder head cover (see illustrations) .

… and the bleed screw at the front of the left-hand cylinder head
13 Fill the system by slowly pouring the coolant into the expansion tank to prevent airlocks from forming.
14 If the coolant is being renewed, begin by pouring in a couple of litres of water, followed by the correct quantity of antifreeze, then top-up with more water.
15 When air-free coolant emerges, tighten the bleed screws.
16 Top-up the expansion tank to the correct level, then refit the expansion tank cap.
17 Start the engine, run it at 3000 rpm for 1 minute, then allow it to idle for 5 minutes. Repeat this procedure until it reaches normal operating temperature, then stop the engine and allow it to cool.
18 Check for leaks, particularly around disturbed components. Check the coolant level in the expansion tank, and top-up if necessary. Note that the system must be cold before an accurate level is indicated in the expansion tank. If the expansion tank cap is removed while the engine is still warm, cover the cap with a thick cloth. Unscrew the cap slowly, to gradually relieve the system pressure (a hissing sound will normally be heard). Wait until any pressure remaining in the system is released, then continue to turn the cap until it can be removed.
19 Refit the radiator access panel, engine cover and spare wheel (where applicable). Lower the vehicle to the ground.

Brake (and clutch) fluid level

Warning: Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it.
Warning: Do not use fluid that has been standing open for some time, as it absorbs moisture from the air, which can cause a dangerous loss of braking effectiveness.
HINT: The fluid level in the reservoir will drop slightly as the brake pads wear down, but the fluid level must never be allowed to drop below the MIN mark.

Before you start

8 • Make sure that your car is on level ground.

Safety first!

9 • If the reservoir requires repeated topping-up this is an indication of a fluid leak somewhere in the system, which should be investigated immediately.
10 • 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.
Release the clips and remove the plastic cover from the right-hand side of the engine compartment.
The MAX and MIN marks are indicated on the side of the reservoir. The fluid level must be kept between the marks at all times.
If topping-up is necessary, first wipe clean the area around the filler cap to prevent dirt entering the hydraulic system.
Disconnect the level sensor wiring plug, then unscrew the reservoir cap and carefully lift it out of position,taking care not to damage the level switch float. Inspect the reservoir, if the fluid is dirty the hydraulic system should be drained and refilled.
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

11 • Park the vehicle on level ground.
12 • Set the steering wheel straight-ahead.
13 • The engine should be turned off, and the fluid cool.
HINT: For the check to be accurate, the steering must not be turned while the level is being checked.

Safety first!

14 • The need for frequent topping-up indicates a leak, which should be investigated immediately.
The reservoir is located on the left-hand side of the engine compartment. The minimum and maximum levels are indicated by marks on the side of the reservoir. The fluid level should be between MIN and MAX.
If topping-up is required, wipe clean the area around the reservoir filler neck(s) and unscrew the filler cap(s)from the reservoir.
When topping-up, use Texaco 14315 Cold Climate PAS fluid and do not overfill the reservoir. When the level is correct,securely refit the cap(s).

Screen washer fluid level

15 • Screenwash additives not only keep the windscreen clean during foul 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 too diluted, and will freeze during cold weather.
Caution: On no account use coolant antifreeze in the washer system – this could discolour or damage paintwork.
The screen washer fluid reservoir is located in the front, left-hand corner of the engine compartment. If necessary, remove up the cap.
When topping-up, add a screenwash additive in the quantities recommended by the manufacturer. It could also be time to replace the wiper blades. For details, click below

Wiper blade replacement

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. Wiper blades should be renewed annually.
To remove a front wiper blade, pull the arm away from the screen, squeeze together the sides and pivot the cover upwards.
Press apart the clips and slide the blade from the arm.
To remove a rear wiper blade, pull the arm away from the screen, use a screwdriver to depress the tab, and slide the blade from the arm.
