SRiTez Hi all, just a quick question. My inlet manifold is sucking air, do I need to drop the coolant before I remove it or can I just unbolt it to check the seals?
figo126 is it astra z22se ? just un bolt it , no water runs through it ,you will need to take the injectors out first , and all the wires and dipstick will make it a pain ,🙂
