Lotus Esprit Heater Hose Routing Diagram - Water Valve, Diverter & Recirc Pump
Coolant/heater hose routing schematic showing water valve, heater core, diverter valve, recirc pump and numbered hoses.
This document is a parts/hose-routing schematic for the heater and water valve plumbing on a Lotus Esprit (the word 'ESPRIT' appears at the bottom left). It is an exploded-view line drawing showing the heater matrix/core (item 1), water valve, diverter valve, recirculation ('recirc') pump (item 19), and the network of coolant hoses, clamps, and fittings that connect them, identified by numbered callouts (items 1 through 27, with item 2 repeated for clamps). A member of the community has annotated the scan with bold labels identifying the 'water valve,' 'diverter valve,' 'recirc pump,' and the 'hose feed to water valve,' plus two questions about coolant flow direction: 'direction of flow?' near the water valve hoses and 'what direction does this flow ?' pointing at a long hose (item 20). No legend/parts table, part numbers, or dates are visible on this page — only the numbered callouts and the annotations. A reader can learn the physical routing and connection points of the Esprit heater circuit hoses, the relative locations of the water valve, diverter valve, and recirculation pump, and which numbered hoses feed the water valve.

Frequently asked questions
- What Lotus model does this hose diagram cover?
- The diagram is labeled 'ESPRIT' at the bottom left, so it covers the Lotus Esprit heater/coolant hose routing.
- What components are identified on this schematic?
- Annotations identify the water valve, the diverter valve, the recirc (recirculation) pump (item 19), and the hose that feeds the water valve (near items 12 and 13). Item 1 is the heater matrix/core shown at center.
- Does this diagram include a parts legend or part numbers?
- No. Only numbered callouts (1 through 27) appear on the drawing; no legend, part numbers, or descriptions are printed on this page.
- Which callout number is the recirc pump?
- The annotation 'recirc pump' points to the cylindrical component labeled item 19.
- Which items are associated with the hose feed to the water valve?
- The 'hose feed to water valve' annotation points to the hose at the right side of the diagram near callouts 12 and 13, with the diverter valve labeled at item 13's location.
