Coolant flow diagram
I'm trying to understand the coolant flow route and came across this which may help owners. Anybody know where it came from and can identify the components?

Out of radiator... 1 oil cooler 2 Pump 3 thermostat 4 through engine 5 back out from top of engine, to top of rad The alternative route when stat is closed is... 1. output from top of engine 2. through FBH (if fitted) 3. through heater matrix 4. to pump 5 through engine Basically the flow is continuous around the engine, heater matrix, FBH, pump and past the thermostat at all times. If and when the thermostat opens, it allows a bypass via the radiator and oil cooler when it gets hot enough. Obviously that is not quite correct, so I would welcome any corrections.

Does anybody know where the instrument panel engine temperature gauge sender is located on the diagram and also the diagnostics source of temperature data if different as it probably is, one being electrical the other being electronic.

All three temperature sensor sources are one and the same unit, where it is located, I don't yet know.

That's wierd, it looks as if two flows converge on the, I think the thermostat, from different directions that can't be right surely
