Right, this isnt a hard job and will save you a considerable amount of money than if you took it
to a garage.
The pics are from my gen 3 1.6 but its basically the same procedure on all cars. Should take less than an hour if you have the right tools.
Tools i used:
Oil filter (Â£2.99 - halfords trade price)
Oil (I used castrol magnatec 10w-40)
Jack + Axle stands or other method of lifting the front of the car safely
17mm Spanner or rachet and socket
Oil drainer or something to catch the old oil in
Oil filter removal tool (can use a big screwdriver through the middle of the filter if you dont have access to one)
Kettle, Mug, Tea bags, Sugar and Milk.
First off lift the car off the ground using jack or ramp
Using a 17mm spanner, locate and undo the sump plug, the trick is to loosen until hand tight then lift the plug up and away quickly so you dont cover your arm in (possibly warm/hot) engine oil.
Please dispose of your old oil properly, not down drains/sinks etc. after oil has drained and your down to a trickle, replace the sump plug and tighten with spanner/ratchet nice and tight(dont go mad though)
Locate your oil filter, which is on the front of the engine on 1.6/2.0 not sure about the V6
i removed the little plastic piece underneath just to make it easier but this can be left on if you dont want to take it off.
Using the oil filter removal tool loosen the old filter, as i mentione dif you dont have access to the tool, you can hammer a large flat blade screwdriver through the middle of the filter and use as a lever to undo the filter, however this is messy!
Use the same method as the sump plug with something to catch oil as the filter holds oil, remove by hand
Take new filter, and apply a thin film of new or used oil to the rubber ring, this stops the filter sticking to the engine, making it 10x harder to get off when you next do an oil change
Put new filter on, TIGHTEN ONLY BY HAND do not use tools. Hand tight is enough. Replace plastic cover if you removed it.
Finally, lower car to the floor, put in 3 litres of oil, and start engine, leave for a minute or two, stop the engine, check your dipstick and top up as required to max level on dipstick. It is important you start your engine and then top up as pouring in oil and checking will give a false reading due to the oil fiter and some other parts being empty of oil.
Fire up the kettle and have a congratulatory brew
