mine runs around these temperatures whilst on the move. after a good heatsoaking she will rise to 90 to 92 ish. at a standstill in heavy traffic she runs pretty much the same as the plastic original did. up to 104 ish fan on and back down to 95. yes your right simon it does run below optimum temp designed for the engine but seems to cope fine. however im on lpg anyway and i dont think the running temps etc would be the same as on petrol or maybe they would ....
