Im having a go at replacing an Alternator on a Corsa D 2004 1.4 . According to a service manual the inlet manifold needs removing , said manual is here . Seems to make sense since the Alternator terminals are hidden behind this manifold .. My guess is I need to de-pressure the Schrader valve by depressing the valve , and then just unbolt this line with a regular spanner ( the manual states a special tool )? Also how do I remove this guy below ? Didnt wanna break it

Hi Just picked up a cheap agila 1.2 2002 project car for a few hundred quid, to sell onto a family member It had an abs light up on dash, according to ODB tool it's a solenoid valve malfunction (see attached). I belled out the fuses under dash and within engine bay, they seem fine (not sure about the relays though :s) . So this far I am guessing the ABS module has failed. I had ordered a replacement used ABS pump , since they are cheap I'm gonna have a go at fitting it, plenty of room around module . Though Before I start the swap , just wondered if I was on the right track ? thanks
