When I go through a lot of water, heavy rain puddles, the power steering seems to go! Any ideas?

Not sure what you mean by 'seems to go'
Aquaplaning?............

if its just for a brief moment i agree it does sound like aquaplaning and the weight of the water on the wheels, its not gone just feels that way....

if its longer and you are def loosing power i'd look at a short somewhere, maybe water getting into the pump?

I mean, the driving goes very heavy just for a few seconds, its very noticacble. I think aquaplaining just goes light not heavy. My mum had a car with no power steering and that was heavy when parking it. That is what I meant, sorry if it was not clear enough.

Is this when your going quickly or slowly? If it at speed ( say over 30mph) then its probably just the weight of the water on the wheels.

The only way i know that power steering would go is lack of fluid in the system, a stretched belt or faulty electrics. First thing to do is check your level of fluid, if its low then it could be the extra strain is causing this, then check the belt to the steering pump, again if this is slack it may be it... i guess its "possible" that water is splashing up from the wheels onto the belt causing it to slip, this is why you're loosing power, but i'd be surprised, unless some protection is missing, inner liner or something?

Finally it could be electrical, but the fact it comes back again, says maybe not...

Have a check of these bits, but ofyou're not sure get a mechanic to look over it, last thing you want is a steering failure at speed !!

Don't think it will be electrical...at least on my 2.8 its entirely hydraulic...the variable assistance provided by a trachoid pump.
Low fluid or belt slip as Andy suggests.....do you get any banging or grinding noises whilst the power assistance is out?

No, just the steering heavy for a few seconds. My tbelt light has come on though as I went past the magical 100000 km last week

Hey there.

Off topic to do with the SC, but my Hiace work van (3l Diesel - Non-Turbo), does the same thing and I understand what you mean.

You drive through a puddle and after you have been through the puddle the steering becomes heavy, It isn't Aquaplaning as you have already been through the water, it is just after, the work van is going into get the top arms looked at so I will bring the point up and see what they can find. Will post back here if I can find out.

Your problem is almost certainly a slack power steering belt. When you go through water the belt slips making the steering heavy. It happens on any vehicle , not just the SC .
