as the 1st step I'd pop the belt off and have a feel of all the pumps and pullies all should turn freely with no tight spots

if you feel the power steering is tight then I'd 1st suggest replacing the fluid with fresh as this can make a big difference

Yeah I'm not sure how to take the belt off. Never worked on this car before.
Customer: replied 1 year ago.
Do I have to remove the power steering pump to replace the belt? The old one needs to be replaced.

OK when you look into the engine bay on the LHS you should see the belt running over its pulleys and there will be a tensioner on a sprung loaded arm that pushes against the belt.

its always a good idea to take a photo of the belt run beforehand

You may find access easier if you remove the driverside wheel and the engine bay cover inside the wheel arch, but it should be possible to do the job from the top.

Now the tensioner will either have a square hole in the arm or you use a ring spanner or socket wrench on the pulley nut to move the tensioner off the belt whilst your assistant slips the belt off the pulleys.

you then fit the new belt following the same run as before and relax the tensioner back into place, ensure that the belt is square and true on all the pulleys and that should be it
