Hello Scotty. My name is Adam and I had a question for you. I own a 2009 scion xd hatchback and for about the last week or so whenever I drive the car I have noticed that when I accelerate even lightly I start hearing a rattling noise inside the engine compartment. And the car has also been overheating a lot recently. I think that might be a leak somewhere. What advice can you offer? Is it safe to drive my car with that rattling noise? I can usually drive it for about 45 minutes to an hour before the engine overheat warning starts going off. I'm very tight on money so I can't afford a full repair. Is there anything I can do as a temporary measure. Please help thank you.

fix the leak first, do these video tests to find the fault https://www.youtube.com/watch?v=evpaTW2WJ5Y&t=21s
