I drive an '07 Ford Crown Victoria Police Interceptor with 146788 miles on the engine. I was looking under my hood today to swap my air filter when I noticed a hole right on the front of the engine below the alternator and near the crank shaft. It almost looks like coolant is in the bottom of it but I cannot tell. Anyone know what may have caused this and how I can fix it?
That looks like a drain hole to drain fluid from bearings etc.
Make sure before you block it...
It looks like a plastic tube for A/C condensation.
Looks to me from the lack of corrosion in a uniform manner around the hole, like a rubber grommet simply cracked and fell out of there. The people that maintain police cars often put access holes like that in to check things without having to tear them down.
