[Fraz]

yours IIRC the camshat sensor is at the front of the spark plug cover between the camshafts (yours is a Ecotec?)

Lambda sensor should be on the down pipe from the exhaust manifold

What engine is it, on the ecotec the camshaft sensor is on the top with a wire leading to it by the camshaft end of the engine it gives a sensor position for the engine to know when to fire. the lambda sensor is screwed into the exhaust on the let its at the front but i think on the ecotec and ex its further down the exhaust before the cat. it mesures the amount of fuel needed, there both quite easy to change.
To check the fan , find the plug in the bottom of the radiator and short out the two wires and turn ignition on, if it starts its the senderin the radiator.
