I HAVE AN ANTIFREEZE LEAK. I THOUGHT IT WAS THE HEATER HOSE AND REPLACED
IT, BUT I STILL HAVE THE LEAK. IT ONLY LEAKS OVERNIGHT AFTER THE CAR HAS
COOLED DOWN. WHAT WOULD CAUSE THIS TO HAPPEN JUST OVERNIGHT. THERE IS NO
LEAK WHEN THE CAR IS RUNNING OR WHEN IT IS STILL HOT. CAN SOMEONE PLEASE
ADVISE? THIS HAS BEEN GOING ON FOR 3 DAYS.
TURN OFF THE CAPSLOCK!

Then, in the morning, get under the car and look for drips... If from
front of engine, near crankshaft pulley.. it's likely the waterpump
While engine is cold.. remove the radiator cap and MAKE SURE that
coolant is present up to the neck of the opening before you start the
engine, each day until you find the problem.

Also make sure the little cap-like thingy on the underside is free, this
allows coolant to be sucked back into the engine system as it cools.
Wouldnt hurt to just replace the rad cap.
It's ALSO possible that the line from the cap-neck to the de-gas bottle
(overflow ) is blocked.
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
You could always try filling the tank with PURE antifreeze... I know, sounds
weird, but my 99 taurus had a bad antifreeze leak, he had to change the tank
(Very common for the tank to crack) but there was still a leak, only when the
car was stopped and shut off... I was stranded by a dollar store, and bought
antifreeze, but I didnt have water to mix it with, so I had no choice but to
pour it all in... My tank doesnt hold much antifreeze, but some how or other
it keeps enough to keep cool, and its been this way for a year and a half,
never over heated...(you still want to add some every few months or so...
just to be on the safe side... Im not guaranteeing it will work, maybe
something else happened in mine, But, You can always give it a try?
