Easy to replace a failed PS pump, not a rush job.
The power steering pump fit exactly where the OEM pump was located. Your video helped to make the replacement easier. Although I always seem to have a tough time getting the circlip in place to secure the reservoir. That's mainly due to the space restrictions of my car.
The new unit works great once I put everything back together and would recommend it to anyone with patience to attempt.

Where is the pump made and does it come with seals?
I am not able to provide a specific country of origin as we have various locations around the globe. TRQ is a high quality, high-end name brand that we offer and back with our 1A Auto Limited Lifetime Warranty. The seals are not included.
