If your old Nissan power steering pump leaks or it just can't hold the pressure you may need to change it.

Often you may just need to check and add fluid to your power steering pump reservoir but if your broken PAS is too noisy and gives a loud squeaking / whining noise you may want to replace it.
The best thing if you check all hose lines along with replacing your power steering pump on your 180SX, 200SX, 240SX.

Here we offer a brand new Nissan SR20DET power steering pump replacement for the following models:

Nissan 180SX, 200SX, 240SX, S14, S15

This is a non-HICAS power steering pump.

If you have problem with the bracket that can be replaced and used fro your old pump.
