Gates 51380 upper radiator coolant hose for the 1999-2002 Land Rover Discovery V8 4.0L and the 2003-2004 Discovery V8 4.6L carries coolant between the engine and the radiator. This Gates coolant hose is modular: it is built with OEM-exact hose components, here one branch and a drain.
- Molded modular hose with one integrated branch and a drain
- Specifically engineered materials resist collapse under vacuum
- Engineered to resist electrochemical degradation, the leading cause of hose failure
- EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover
- Meets SAE 20R3 EC Class D1 under 25 mm (1 in.) ID and SAE 20R4 EC Class D1 for 25 mm (1 in.) ID and over
- Temperature range of -40°F to +257°F (-40°C to +125°C)
Quick facts

A coolant leak at the hose, a swollen or cracked hose body, or a soft hose that collapses can mean it is worn. With the engine off and cool, look it over for cracks, bulges and wet traces at the ends before replacing it, because other cooling parts can leak too. If this hose is the cause, this one replaces it.
Fits
This hose is a direct-fit replacement for the 1999-2002 Land Rover Discovery V8 4.0L and the 2003-2004 Discovery V8 4.6L.
