FIrst time here so I appreciate any help. 1997 Camry XLE with 208k miles in Michigan. Last winter I had to keep refillilng the PS fluid but the problem went away when spring came. No problems thru summer or fall. This past week when it sat in the cold weather the problem has returned. Hard to steer and fluid needs to be replenished. Appreciate any guidance on what to start with - pump, hoses and why only when it gets cold. Really appreciate help.
