Your knocking noise sound like you could have a brake booster going bad. What do you feel in the brake pedal? do you feel the knock?
By "running hot" you mean at temps above 240 degrees F?

Need more input!!! How are the brakes? Do they stop the vehicle in a average amount of time?? Does it sound like it is metal to metal?
And im agreeing with Euro how hot is hot?? And do you always have to add coolant?
