Hi, I have just purchased a 2002 is200 sport and I have a coolant leak. At the moment I can't find any wet patches in the engine bay or under the car but I have noticed a pink ish dried residue at the front left of the engine, I'm thinking is the water pump. There is no White oil in the filler cap so I'm ruling out the head gasket. Is there anywhere else I should be looking or should I just change the pump? Is it also worth changing the cam belts as I can't seen any history of it being changed. The car has now covered 85000 miles.
Cheers
Lee
