Coolant, I believe, is most likely leaking at the head gasket area due to lost torque from the original cylinder head bolts. This is where you get the overheating and where coolant creeps out of, very difficult to spot at times since it runs along the exterior of the engine block thus usually burnt off by hot engine. Land Rover addressed this issue by releasing an uprated oil rail in 2005, specifically for the 1.8 Freelander. To do this correctly and to do it first time, renew the head gasket + renew the oil rail + use Hylomar sealant for head gasket (use 2x coats on each of the following, both sides engine block face, both sides shim, both sides new head gasket, nil for the cylinder head). I videoed this project, since which, my Freelander has never run more quietly and smoothly and no more temperature needle creeping past the half way mark and importantly, no more coolant loss.
