it can become hot if there is a lot of turning while driving but it usually goes back to being a just above warm. if yours has a cooling rad on the front lines, you can check it as sometimes the veins inside  get blocked and this will limit the flow and make it hotter than normal. some of the old power steering fluid had water in the mix and this can cause a build up of rust in the lines and block the flow. had it on a renault 3.0 auto. had to change the cooler.

Steering cooler on the Omega is a simple pipe loop across the front of the aircon condenser.

the reason i asked I experienced a sudden loss of fluid & I,m not sure but it seemed to come out from the fluid reservoir cap. it was an extremely hot day & did a lot of country lane driving consisting of loads of bends. the fluid was the colour it goes when it gets too hot. I did put a pump in a couple of months ago & I have checked that & all is good. it never effected the steering & the only way I realised it had leaked from somewhere is when I arrived back home & had to do a full left hand lock to reverse into a parking space. I had left a trail of fluid.

The only thing that can think of if it's coming back out the filler is it's got air in the system or the vent hole is blocked. It could also be the wrong fluid in system. Sports types are thiner for higher. Could even have a blockage in the rack or pump. A bit of muck could of gotten In the line when fitting newer pump.

  what I omitted to say your theory re air in the system , I did detect a load of bubbles in what was left in the reservoir. tho I had been driving the car since mid may with no bother

if you have bubbles it can be a line is sucking in air. when the air builds up only place to go is back out. does the steering make any strange sounds while its in use or when the front is off the ground. best to do the bleed with front of the ground as no pressure on steering from engine and body shell. so the rack is lose and can move more freely.
