The aluminum Rover V8 has a long reputation for running warm, and slow speed work makes it worse, since low engine speed means low coolant flow and limited airflow through the radiator right when you need cooling the most. This pump is built to address exactly that.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe difference is in the impeller. FlowKooler machines it from billet aluminum with an increased vane count and a tighter plate to impeller clearance, so it moves more coolant and builds more head pressure than a standard pump, especially at low rpm. Moving coolant through the block, heads, and radiator more quickly gives the system more chances to shed heat, which helps hold temperatures down in stop and go traffic, while towing, and during slow technical off road driving. The impeller carries a Type II Class II military grade surface coating that resists corrosion from old or contaminated coolant.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis pump fits the V8 EFI engine across the Discovery I and Discovery II, the Range Rover Classic and Range Rover P38, and the Defender 90, covering the 3.9, 4.0, 4.2, and 4.6 liter versions of the Rover V8. It is a direct replacement for STC4378 and also covers the STC4434 and STC1693 numbers. Always install a water pump with a fresh gasket and clean sealing surfaces for a leak free seal.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cspan\u003eFits:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDiscovery I (1994 to 1999) 3.9 and 4.0 liter Rover V8 Petrol\/Gas\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDiscovery II (1999 to 2004) 4.0 and 4.6 liter Rover V8 Petrol\/Gas\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRange Rover P38 (1995 to 2002) 4.0 and 4.6 liter Rover V8 Petrol\/Gas\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRange Rover Classic (1995) Rover V8 Petrol\/Gas, serpentine belt only\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDefender 90 (1997) 4.0 liter Rover V8 Petrol\/Gas serpentine belt only\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003ePart Number:  FCSTC4378KIT\u003cbr\u003eFree shipping to the lower 48!\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e[Supersession Part Numbers]\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eReplaces Genuine Land Rover STC4378.

This FlowKooler pump uses a CNC machined billet impeller with more vanes and a tighter clearance, so it moves more coolant and builds more pressure, particularly at low rpm. That extra flow is what helps keep the Rover V8 cooler during slow off road work, towing, and hot weather idling.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eDoes it come with a gasket?\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cspan\u003eYes.
