Fast shipping and product was well packaged. Does not come with replacement bolts but DOES have replacement gasket, no sealant though.

Thank you all for the video as well! I decided to replace the Viscus fan at the time of the water pump as recommended. Glad I did. Keeps our truck cooler when we're pulling our Airstream. By the way, You all Rock! I'm new to the Land Rover Disco II (02'). Thanks to you all I can work on this monster with confidence as a (now) competent home mechanic.

This product was much better than my old leaking water pump. The included pump and gasket kept my coolant in my Disco 2 and off of my driveway. It seems comparable to OEM except for cost.

This came in very quickly, and was even better than I expected. In the OEM version, there was a small silver plate behind the pump blade which had rusted and broken. In this model, that was solid cast so way more durable.
