Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am sorry that you have not been helped yet.
A few questions to help me out in diagnosing.
How quickly does it overheat?
Does the coolant get forced back out the coolant reservoir tank?
Any hoses collapsing?
Is the radiator hot at the top and ice cold at the bottom?
Are the heater hoses getting hot?
Is it going thru coolant without visible loss?
Please remember that I am not there and therefore rely on you for as much information as possible, so answering the above questions will help greatly in diagnosing
