Leaks & Noises
Hi please help, i have a vauxhall insignia with 25000 on it. The car was overheating due to the cooling system having an air lock in it. The water pump has been replaced, head gasket has been tested which had no fault, also the cooling system has been presure tested and no leak was found. Despite the coolant system having been repeatedly bled. There is still air getting into the coolant system. Plesse advise will be very grateful.

To be honest the only way air can enter the coolant system is thru the head gasket of a cracked head. How was the head gasket tested.
Is the water bottle clear enough to look for bubbles.
I honestly can't think of any other way for air to enter the water.
Sorry

Why not get a block test done this will confirm if there are any gases in the cooling system then you can take it from there.
