“While driving my 1996 Cougar this past september, which has only 40,360 miles on it and is stored most of the year for the purposes of collecting and preserving the vehicle indefinitely, at low speeds I noticed the obvious sign of coolant and the smell of coolant coming from up under the hood. I then shut the vehicle down right away and discovered coolant running onto the ground below. Now, being of an experienced nature with automobiles and using close observation of the problem it appeared to be emanating from the front of the intake manifold. …”

“I was driving and saw my low coolant light was on. Pulled into car parts company parking lot. Opened hood saw coolant on top of motor and underside of hood. Coolant was leaking from front of the intake manifold. Upon inspection realized the manifold is made of plastic. I attempted to stop the leak with plastic repair and a coolant system repair, no use. Had to limp the car to zender ford in spruce grove, alberta. They are fixing the car at an estimated cost of $900.00 no warranty or recall. Left me stranded 400 km's from my home.”

When I opened the hood, I found that there was crack in a plastic part coming directly off of the engine block to a coolant hose. I went to several auto parts stores to identify the part and found it was a crack in the intake manifold water cross-over jacket causing coolant leak. The stores did not carry a replacement, so I called the ford dealership. …”
