Well, don't take this personally, but you need to send your car to a mechanic.
It would be irresponsible for anyone here to try and help you, give you the quick answers you desire.
If you cannot work out what needs to be done.. the very basics to do such a task, then you are not up for it, let alone the related responsibilities that go with it. You stuff up, you crash, you kill someone else. It doesnt work like that; its not going to work like that.
Sorry, but this thread will be closed. If your that saddened by it, ill personally send you a bottle of power ade for the time you spent out in the heat.
