genital fluid

edited to remove genital liquid, which had to be typo.

Automobiles do possess petcocks, I think every radiator has a drain petcock.

petcocks
petcocks are also used on aircraft

Steam locomotives have petcocks on the cylinders, to purge condensation from the cylinders and avoid hydro-lock after they've been stationary. That is why steam billows from a locomotive's cylinders when it leaves a station.

Petcocks In Radiators
Yes, I agree, almost every vehicle has one on the radiator. —The preceding unsigned comment was added by Special:Contributions/ (talk)

Other danger of overflow of fuel
You can severely damage some parts of the engine if there's too much fuel in the engine. Remember: Liquids don't like compressing and thus spread force quite well. Some parts aren't meant to be exposed to that much force. Anyone got a citation from a motorcycle/scooter manual or something to back this up? It would be nice if this article had some references to automotive books or sites of reputable experts. 71.196.246.113 (talk) 02:05, 5 May 2012 (UTC)

Failed Petcock Symptoms
It may be worthwhile having a section on symptoms of a failing, or failed, petcock. Many readers interested in this topic may be searching for info because they are having equipment problems.

My scooter (2001 Yamaha Riva 125) has a automatic vacum controlled petcock that has failed. As a result, gas in the tank is feed to the carburator, even when the scooter is not running, which overflows and leaks onto the ground.

This failure often starts out as a 'gas smell' and eventualy [over a period of months or years] fails completely with gas pouring onto the ground. — Preceding unsigned comment added by 98.111.12.45 (talk) 12:47, 7 October 2012 (UTC)

Petcocks In Swimming Pool Equipment
Swimming Pools also have petcocks. They are commonly used on heater headers as a winterizing drain valve. They are also used on filter tanks as an air relief valve Sigfod (talk) 14:01, 11 April 2013 (UTC) Sigfod
