You have the hoses crossed
The engine itself creates Vacuum once it is running.
On a 1996 Ford Mustang : To adjust the clutch : - without the engine running , put your transmission in 1st gear - GENTLY , with your foot , pull the clutch pedal UP until it stops moving - SLOWLY push the clutch pedal DOWN all the way ( if you hear a click the clutch needed adjusting and has adjusted itself )
It should be on the engine block itself which would mean you would have to take the whole engine out to get to it or go underneath it to get it.
In a 1973 Mustang with a 351 Cleveland engine, the temperature sending unit is typically located on the intake manifold, near the thermostat housing. It is usually threaded into a port on the manifold itself, allowing it to measure the coolant temperature as it circulates. This position provides an accurate reading of the engine's operating temperature.
Ventilation. Make sure doors and windows are open in the garage as well as the windows of the car itself.
What kind of car are you working on? And what engine? On some cars the exhaust A-pipe will need to be removed. On some four wheel drive trucks the front differential may need to be removed, or even the engine itself. On other cars it is a piece of cake to replace. It all depends.
The timing chain itself is not hard to change , but the engine has to be removed to do it, that is why it is such a costly job if taken in to a garage . a common fault i believe on these engines .
if all faults removed from engine the light should go out by itself but if not disconnect battery and wait 10 mins thenn will be out unless fault still in system
If the wheels turns to the right by itself with the engine running the steering gear or rack and pinion has failed.
Under the lower intake manifold... the entire manifold must be removed which is a 2.5hr job... and you will see it on the engine block itself.
No. Unless there is some other problem, leaving a car running overnight will not harm it at all.
The blower motor will operate when the key is in run regardless of whether the motor is running. The AC itself is not operating as the compressor is turned by the motor.
