3Slacken the drain plug about half a turn.
Position the draining container under the drain
plug, then remove the plug completely. 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 the stream
of oil issuing from the sump runs into the
container, not up your sleeve! Recover the
sealing washer from the drain plug.
4Allow 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.
5After all the oil has drained, wipe off the
drain plug with a clean rag. Check the sealing
washer for condition, and renew it if
necessary. Clean the area around the drain
plug opening, and refit the plug. Tighten the
plug to the specified torque.
6Move the container into position under the
oil filter.
7Using an oil filter removal tool if necessary,
slacken the filter initially, then unscrew it by
hand the rest of the way (see illustration).
Empty the oil from the old filter into the
container, and discard the filter.
8Use a clean rag to remove all oil, dirt and
sludge from the filter sealing area on the
engine. Check the old filter to make sure that
the rubber sealing ring hasn’t stuck to the
engine. If it has, carefully remove it.
9Apply a light coating of clean engine oil to
the sealing ring on the new filter, then screw it
into position on the engine. Tighten the filter
firmly by hand only - do notuse any tools.
Wipe clean the filter and sump drain plug.10Remove the old oil and all tools from
under the car, then lower the car to the
ground (if applicable).
11Remove the oil filler cap and withdraw the
dipstick. Fill the engine, using the correct
grade and type of oil (see “Lubricants and
fluids”). An oil can spout or funnel may help to
reduce spillage. Pour in half the specified
quantity of oil first, then wait a few minutes for
the oil to fall to the sump. Continue adding oil
a small quantity at a time until the level is up to
the lower mark on the dipstick. Finally, bring
the level up to the upper mark on the dipstick.
Insert the dipstick, and refit the filler cap.
12Start the engine and run it for a few
minutes; check for leaks around the oil filter
seal and the sump drain plug. Note that there
may be a delay of a few seconds before the oil
pressure warning light goes out when the
engine is first started, as the oil circulates
through the engine oil galleries and the new oil
filter, before the pressure builds up.
13Switch 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
completely full, recheck the level on the
dipstick, and add more oil as necessary.
14Dispose of the used engine oil safely, with
reference to “General repair procedures”in
the Reference section of this manual.
1Firmly apply the handbrake, then jack up
the front and rear of the car and support it
securely on axle stands (see “Jacking and
vehicle support”).
2For a quick check, the front brake disc pads
can be inspected without removing the front
wheels by inserting a mirror between each
caliper and roadwheel(see illustration).If any
one pad is worn down to the minimum
specified thickness, all four pads (on both
front wheels) must be renewed.
3It is necessary to remove the rear wheels in
order to inspect the rear disc pads. The pads
can be viewed through the top of the caliper
after removing the blanking spring clip(see
illustration).If any one pad is worn down to
the minimum specified, all four pads (on both
rear wheels) must be renewed.4For a comprehensive check, the brake disc
pads should be removed and cleaned. The
operation of the caliper can then also be
checked, and the condition of the brake discs
can be fully examined on both sides. Refer to
Chapter 10 for further information.
5On rear drum brake models, the brake shoe
friction material can be inspected for wear
without removing the roadwheels. Working
beneath the vehicle, prise the plug from the
brake backplate, and using an inspection
lamp or torch, check that the friction material
thickness is not less than the minimum given
in the Specifications(see illustration).If any
one of the shoes has worn below the
specified limit, the shoes must be renewed as
an axle set (4 shoes).
6At the same interval, check the function of the
brake fluid level warning light. Chock the wheels,
release the handbrake and switch on the
ignition. Unscrew and raise the brake fluid
reservoir cap whilst an assistant observes the
warning light: it should come on as the level
sensor is withdrawn from the fluid. Refit the cap.
7On completion, refit the wheels and lower
the car to the ground.
1Visually inspect the engine joint faces,
gaskets and seals for any signs of water or oil
leaks. Pay particular attention to the areas
around the rocker cover, cylinder head, oil
filter and sump joint faces. Bear in mind that
over a period of time some very slight
seepage from these areas is to be expected
but what you are really looking for is any
indication of a serious leak. Should a leak be
found, renew the offending gasket or oil seal
by referring to the appropriate Chapter(s) in
this manual.
2Similarly, check the transmission for oil
leaks, and investigate and rectify and
problems found.
3Check the security and condition of all the
engine related pipes and hoses. Ensure that
all cable-ties or securing clips are in place and
in good condition. Clips which are broken or
missing can lead to chafing of the hoses,
pipes or wiring which could cause more
serious problems in the future.
