Caution: Be sure of your pump OEM part number. Most of the power steering pump housings look identical with the pressure port pointing to the same direction. Therefore, you should be aware of the direction of rotation. Because if you don not choose the correct pump OEM number, the pump you are ordering will not work. For OEM PEV181618R101 Perfect Fit is a must for Steering Pumps. PSR pumps are precisely built to ensure proper Fit and Performance but will only work if you order the correct OEM number. Please confirm you are ordering the correct OEM number to save time and money. The OEM number may be found on the old pump you are replacing. All of our pumps have a one year warranty from date of purchase.
