A Mystery Auto Parts Purchase

The Puzzler

RAY: This was sent in by Tom Downs. He writes:

The other day I was in the local auto parts store and a teenage boy came in and said, 'I want a 710 cap.'
The parts manager asked, 'A 710 cap, what's that?'

The kid said, 'You know, it's right on the engine. I lost mine.'

The manager replied, 'Well, what does it do?'

The kid said, 'I don't know what it does. I'm a new driver and my father made me promise that every time I drive the car, I open the hood and look around underneath to make sure that the belts look all right, the fluids are full and the hoses are okay. And the other day, I noticed that this 710 cap was missing and I needed a new one.'

'What kind of a car is it,' the fellow behind the counter asked, thinking perhaps he'd luck out and the car would be an old Datsun 710.

The kid said, 'It's a Buick.'

The parts manager asked, 'How big is this part?' And the kid made a circle with his hands that was about three inches in diameter.

Finally, the manager asked, 'Can you draw me a picture?' The kid drew a cap and wrote 710 on it. While he was drawing it, I was looking over his shoulder and I had no clue what the part was. But the guy behind the counter stifled a laugh and said, 'I know exactly what you want.'

What part did the kid need?
