Frank, do you hear that strange noise?
Yes, I have noticed it for a while. It seems to be coming from the motor.
What shall we do?
I don't know. Perhaps if we slow it down we can stop at the next park place and check what is the matter.
OK, Let's do it.
Oh, it is burning hot, We have run out of water.
How is the motor itself? Is it OK?
I think it's all right. Let's wait till it cools down a bit.
