The vehicle heat exchange control has a closed coolant circuit with a branch (5) with a coolant/oil heat exchanger (6), and a second branch (7) for the passenger compartment air heater (8). The coolant flow is via a computer- controlled valve (10) which has one position in which the coolant is circulated round the engine (2) alone for faster warming-up. In other positions the heated coolant is fed to the radiator and passenger compartment heater. |
