Mustang guys please help!

OK so she’s got a broken vac line. Good. No cooling problem. If the car’s running OK then it might just operate the EGR or something. She should be fine driving it like that short term.

Check/top off the power steering fluid and see if the noise goes away. If it does then she can drive home because the worst thing that can happen is she loses power steering.

!!!Just warn her not to take any turns fast after she’s been driving a while. If the fluid leaks enough while she’s just cruising down the highway and she then proceeds to try to make a turn with one hand she could end up going straight into something when she can’t turn the car fast enough. Just warn her that the steering wheel might get all stiff all of a sudden.

If topping off the fluid doesn’t work, then she should probably get that looked at and/or fixed before a 500 mile drive.
