An intake manifold (42) for a compact internal combustion engine (10) includ es a pair of arms (76, 78) having air passageways (80, 82) and coolant passageways (90, 92) formed therethrough. The air passageways (80, 82) coupl e an air inlet (66) at a carburettor flange (60) to respective air outlets (68 ) at the ends of the arms (76, 78). The coolant passageways (90, 92) couple coolant inlets (84, 86) at the ends of arms (76, 78) to a coolant chamber (8 8) having a first and second coolant outlet, the first coolant outlet (94) providing a first coolant path for connecting the coolant chamber (88) to a radiator assembly (54), and the second coolant outlet (96) providing a secon d coolant path for connecting the coolant chamber (88) directly to a coolant pump (46). A thermostatic valve disposed in the coolant chamber (88) directs the engine coolant along the first and second coolant paths as a function of coolant temperature.
