I have got a problem with a mk4 astra, i think the water pump has totaly gone. There has been a sort of rattle sound around the cam area and yesterday the sound got really loud, then lost prettty much all power, the engine managment light came on so quickly stopped and turned off the engine the coolant was also boiling. After that it woulnt start. now the crank does not turn and the starter motor just makes a funny spin noise.
I took the top cam sprocket cover off and the pumps sprocket is bent and not sitting straight so im guessing the bearing has failed the cam belt is a little slack too.
I wanted to take the lower cover off to have a better look but i think the crank pulley needs to be removed. is this right? So i went to line the marks up on the cam pulleys and noticed there are painted marks and like a notched mark.
Does this look right or has the belt slipped because of water pump failure. Looking in the manual it looks as if the painted marks should meet but looking at this the are totaly out?
Can anyone help.
