Is there a sensor on top of thermostat housing? Is that a power steering res. on the far left corning of firewall?


It would help to know the vehicle make model and year. Most thermostat housings have a sensor. The reservoir for power steering is near the power steering pump closer to the front of the engine. At the firewall you should see at least one reservoir and that would be for the brakes. If there is another reservoir on the firewall, it will be for the clutch for a manual transmission.

How do you bleed the power steering on 2004 escape


CAUTION: If the air is not purged from the power steering system correctly, premature power steering pump failure can result. The condition can occur on pre-delivery vehicles with evidence of aerated fluid or on vehicles that have had steering component repairs.
  1. NOTE: A whine heard from the power steering pump can be caused by air in the system. The power steering purge procedure must be carried out prior to any component repair for which power steering noise complaints are accompanied by evidence of aerated fluid. Remove the power steering fluid reservoir cap. Check the fluid.
  1. Raise the front wheels off the floor. For additional information, refer to Section 100-02 .
  1. Tightly insert the stopper of the vacuum pump into the reservoir.
  1. Start the engine.
  1. Install the vacuum pump, apply vacuum and maintain maximum vacuum of 68-85 kPa (20-25 in-Hg).
  1. CAUTION: Do not hold the steering wheel against the stops for more than 3 to 5 seconds at a time. Damage to the power steering pump can occur. Cycle the steering wheel fully from stop to stop 10 times.
  1. Stop the engine.
  1. Release the vacuum and remove the vacuum pump.
  1. CAUTION: Do not overfill the reservoir. Fill the reservoir and install the reservoir cap.
  1. Visually inspect the power steering system for leaks.

  • 1 Drain enough coolant from the engine to bring the level below that of the thermostat. Store the coolant in a container that can be securely sealed.
  • 2 Take the upper radiator hose from the water outlet adapter. Remove the upper mounting bracket for the power steering reservoir. Loosen and then remove the bolts on the water outlet adapter, and then remove the adapter.
  • 3 Lift out the thermostat and the O-ring seal. Remove the O-ring seal and throw it away.
  • 4 Set a new O-ring in place on the thermostat. Place the thermostat in position and then replace the water outlet adapter. Torque the water outlet adapter bolts to 18 foot pounds.
  • 5 Replace the upper mounting bracket for the power steering reservoir. Torque the two upper bolts to 13 foot pounds and the lower bolt to 8 foot pounds.
  • 6 Connect the upper radiator hose to the water outlet adapter. Refill the cooling system with the recommended coolant.
  • 7 Start the engine and check for leaks. Turn off the engine and add coolant as needed.

    Where does the power steering fluid go?


    It sucks. Its in far left back corner, behind the coolant reservoir. To get to it, you need to at least remove the coolant reservoir. This is pretty easy as it's just a couple of nuts. But it's still a pain to get to. I don't have small hands so I removed the bolts from the front motor mounts and rocked the car backward to tilt the engine forward. This made the power steering reservoir accessible. This is also fairly dangerous, so don't do it if you're not comfortable.

    I want to replace the thermostat but the power steering reservoir is sitting directly in front of it. What do I need to do to get the thermostat out?


    If you cannot work around the reservoir you will have no choice but to remove it in order to make the repair.

    Where is the thermostat located between top


    On 1998, 4.6 32 valve engines, the thermostat is located in the radiator to block hose. if you look directly under the power steering reservoir you should see it.

    The thermostat has 3 hoses running from it. 2 are approx. 1.5" in dia. and one is approx .750" in dia. The .750" hose leads up to the coolant reservoir. and yes it is under the power steering reservoir. Access to the thermostat is from the bottom side. You will need an 8mm socket to remove the two bolts. Removal of the bottom radiator hose is mandatory.

    Hope helps with this (remmeber rated this help).
