When a hot car engine is turned off after a long drive, you can hear this distinctive 'tic...tic...tic' from the engine compartment. I thought it may be the engine block's metal shrinking that causes the noise but it is far too regular for that isn't it? What causes the noise, exactly?

Thank you John Paul, that answered my question. I was not worried about it, just curious.

TICK sound is mostly the tin shields on the exhaust and tubing contraction. There is no problem continue as normal. Engine block shrinkage that's a good one! It is the light metal parts that heat quickly and cool off fast that tick. And after all that stress is released and the exhaust gets old you won't hear it any more. Then you change over to loose buzz noise when small cracks in tin shields cause vibration noises.

there can be a lot of noises from the engine when you come out of a long drive. It can be the engine pistons moving slowly, soo as to give the car a warm down. It can also be the radiator switch that keeps the radiator running even after the engine is shut down. One thing is obvious, these sounds are most probably produced by a moving object that keeps running after the engine is turned off. it is not a serious thing but if you hear this switch on your engine back again, and keep it on for a while, giving in slow revs in between.
