Water Pump With Gasket STC4378, Original Equipment By Airtex, For Land Rover Discovery I, Discovery Series II, Defender 90 1997, Range Rover P38, And Range Rover Classic 1995
25 reviews 4.9 out of 5 stars
Product Details
Not all water pumps are the same and you typically get what you pay for.
What makes this Original Equipment water pump a best bet for your Land Rover Discovery Series II 1999 – 2004, Discovery I 1994 – 1999, Defender 90 1997 or Range Rover 4.0 and 4.6 1995 – 2002?
- Orginal Equipment means manufactured quality by the genuine manufacturer, just not in a "genuine" box, saving you money!
- Quality internal bearing and housing (lesser pumps have cheap bearings that can often seize-up much faster over time)
- A quality OE gasket that is durable and long lasting (compared to other pumps manufactured with non-spec gasket materials that can often degrade and begin to leak in a short period of time)
This new, original equipment (OE) water pump is a direct replacement for Part # STC4378 built by the genuine manufacturer to exact specifications. The OE distinction means this water pump meets the same quality standards of the part used on the assembly line when your Land Rover was made. Accordingly, our OE Land Rover water pumps are made to the exact specification of your Land Rover or Range Rover.
The water pump is a central component of the Land Rover engine cooling system. When your water pump fails or leaks, that’s a sure sign that your belts, hoses, viscous drive and thermostat should be replaced as well (You’ll have to remove them to reach your water pump anyway!). Get it all done at once and you won't have to worry about them for another 60k+ miles.

Choosing the Best Water Pump:
Recommended: STC4378OE - Water Pump - Original Equipment
This original equipment water pump is the same as genuine - made to the same spec by the genuine manufacturer - it just doesn't come in the "Genuine" box. That means the quality of genuine at a better value price! In addition, this pump includes a higher grade gasket, which means longer performance and lifespan.
Also Available:
The aftermarket alternative. Best value price but not original equipment or genuine quality so expected lifespan is less.

Replaced an original water pump on a 2003 D2. This fit well. If you're doing the same, plan to purchase a Dremel tool and lots of burnishing heads. The old gasket material is a beast to get off. This one looks much better.

With prices, service, and shipping as good as AB on this pump, there is no reason to consider a lower quality part from another vendor. Perfect fit and peace of mind to go with it.
