1966 FB 289 2V C4 Auto Trans with Power Steering, Classic Air and Rally Pak. Approx. 134000 on motor/trans.
A newbie to Mustangs and still learning as I go.
Power Steering went out last night driving home?
Have not had any issues with car operation since I purchased last April other than a leaking radiator which I replaced in August with a 1966 used stock radiator with no problems since being replaced.
Background situation when problem occurred...Outside temp was approx. 50 degrees. Driving home after car sat for about 4 hours from about 20 minutes away in mostly 30 MPH street traffic. Got about 6 blocks from home and manually shifted to 1st gear while stopped at a red light. Drove in 1st for approximately 3 blocks to get some higher rpm's into motor up to about 35 MPH, left off the gas and then manually shifted into 2nd gear at around 2000 rpm and then into "drive". All shifting was smooth and had nor heard any issues from motor or transmission or power steering. Did not have the heater running at this time and had the drivers window down. Oil and temp gauges (stock) were showing at their normal operating levels.
Went to turn left and had no power steering. Although the car was still running the steering felt like the car was turned off. Next block turned right to house and still no power steering. Reversed car into driveway/garage still no power steering. Checked all hoses for leaks etc. and noticed none. With what little daylight was left was able to check P/S fluid level and it was right at the full line. Checked belt tension by thumb pressure and has not changed. (I check all fluids and all three belt's tension on a regular basis meaning every time I drive the car which is almost daily).
Just got back home this afternoon and crawled under car and checked for leaks more thoroughly - none. Current temp is 48*. Car started up fine and let idle in driveway for about 10 minutes to warm up. Drove car around neighborhood in "Drive" only (did not shift into 1st or 2nd manually) for about 10 minutes making both left hand and right hand turns and everything was fine INCLUDING WORKING POWER STEERING
No noises from P/S, motor or transmission.
I am at a total loss as to what could have happened to temporarily lose the power steering??
ANYONE with ANY ideas or some other things to check??
And thanks in advance for all replies and suggestions
