This morning when you, Bill, and Billy Jr. got into your Grand Marquis to go to church, you felt something 'cold' on your foot.

You look down and see 'green' stuff in the floor board...

and another drop falls onto your left foot, just above your shoe, and spreads on your stocking

and you noticed it was a little warmer.

Your first thought, as you spoke aloud, was, "Is my car coming apart?"

Then you turned to Billy Jr. in the back..."What did you do to my car last night?"

Course he denies having done anything to the car on his date, and rightly so, this time.

Your car is not necessarily coming apart...You're heater core is leaking.

The heater core is mounted inside a plastic case, along with the air conditioner evaporator core.

Coolant from the radiator flows through the heater core by way of a couple of hoses, then back to the engine.

This is where you get the 'heat' from when you turn your heater on a little fan blows across the heater core and causes hot air to attack you in the passenger compartment of your car.

When the heater core gets a hole in it, the coolant will leak out... just like the radiator in front of the engine.

Since it's mounted under the dash, it naturally leaks onto the floor and if there is a small foot there, it will probably drip onto it. :-(

There is a long story about *why* the heater core gets a hole in it, but for this article, let's just say it is like the radiator, except it's smaller.

Some of the chemicals in the anti-freeze/summer coolant causes them to deteriorate.

If you will flush the cooling system every other year you can just about eliminate this problem isn't that nice to know?
