this might sound silly but

1. do i have to drain the oil out of the engine?

and 2. do i have to drain the coolant out of the engine also?

im about to start today on the prob :-?

You definately need to drain the coolant (passenger side corner of the rad is a drain tap)

You should change the oil to (drain after the work is done)

Valve at back drivers side of engine (like a tyre valve - take dust cap off, apply rag and release pressure with small screwdriver - mind eyes!

You probably wont see where the knackered one is leaking - only visual difference is that new one will be clean and looks new, old will be "cruddy"

I have never depressurized the fuel lines before removing the unions and have never had proplems.  I just put some rags round the fuel line unions and loosened the unions - hardly anything came out.

I am not an expert though and this is just my experience on a 2.5 petrol. :-?

Be nice if you Keep us posted on you're progress though, as will I.  I am about to change the oil cooler on mine (Have just been rounding all the parts up).

Just a thought, but if you really wanted to test if you're oil cooler was knackered, you could may'be remove it, dry it off, and fiil it with oil and leave it to stand to check for leaks.

ive also been  rounding up the tools. just waiting for my crowfoot spanner to turn up and away i go.

i know everyone says to replace the oil cooler but what if just the sealant/ gasket has gone? :-?

If its just the gasket/sealant gone you will have a water leak only - if cooler gone you will see oil in water.

ok thanx for the clarification

I have oil in the water and a coolant leak.  I'm hoping the sealant on the oil cooler cover has failed so I can sort them both out at the same time.  Otherwise i'll have to start looking for the leak as well...

Whats the chances of the cover seal failing at the same time of the oil cooler itself?...I'm dreading finding head gasket problems while i'm down there, although been told this is unlikely.

Leak could be cover seal, coolant bridge seals, thermostat seal, HBv or a pipe.  Have a good look around mate!

Yep, when stripped down you will see the weaping part.

If its the stat to block joint then use some of the cooler plate goo to re-seal it.

As for the fuel pressure, remove fuse 18 (middle row, 3rd from the right) and start the car before the strip down. The engine will run and then after a short while conk out. This fuse is for the fuel pump so its an easy way of de-pressurising the fuel rail (you will still get some dribble but there will not be any pressure)
