Whilst searching for the RTA Espace manual online I came across this website:http://www.scribd.com/doc/17758536/Rta-Renault-Espace-III-19972002
It has the manual page by page, although it's in French, you can highlight passages of text and paste them into google translate easily enough.
Don't bother to try and download unless you want to pay and subscribe to the sites owners. Nothing is free in this world!!!
I thought it may help somebody out.
My own Espace has a blown head gasket after the water pump failed and I am trying to gain the courage to remove the head, I realise the engine has to drop down through the bottom of the car
Hope it helps!
