Does the 2007 Hyundai Elantra have a power steering pump? How do I check the fluid level? How often should it be replaced? Thanks.
It depends on the type of fluid and level of contamination or heat. if there is no problem with the fluid it should be left alone!
It is not necessary to flush the power steering system in a car. However, you should check the power steering fluid level in the car each month.
You need to flush the power steering fluid on a 2003 Toyota Highlander every two to three years. You should check the fluid levels weekly.
Automatic transmission fluid should be changed according to the manufacturer's suggestions. Many manufacturers suggest having the fluid changed at every 100,000 miles.
If it starts going dark you should probably find out why. Fluids like that are only changed when they indicate a problem. Typically, hydraulic fluid isn't changed since it never gets hot. Heat causes oils to break down and since hydraulic oil doesn't get that hot, the only potential for problems is when the rack&pinion or the power steering pump fails and starts to throw debris.
PS should be 18000 miles and brake fluid about 30000 miles PS should be 18000 miles and brake fluid about 30000 miles
Every 5000 miles.
It's recommended to change the fluid each 30K miles. But can go up 50K easily. I saw ten year old cars with 180K and the fluid was never changed. I've changed mine at 89K because by some reason it had some water in it.
Usually you should change your transmission fluid after 60,000 miles, but to be safe you should check it after 30,000 miles and if it looks like it is low I would add some fluid.
