Ford Taurus 1998 engine coolant reservoir (plastic container) sprung a leak on the bottom side. No indication of any rubbing against anything. I ordered a replacement from an on-line internet parts wholesaler and they said they had many orders for replacement Ford Taurus engine coolant reservoir bottles. I never had such a problem on any previous car that I have owed before.
Stuck thermostat caused a boil over. A few months later the integrated pressure/overflow bottle cracked and caused a major loss of coolant. This also lead to the heater core becoming blocked due to the loss of coolant. Updated 12/07/07.
My whole cooling system has become corroded by the coating inside of the hoses that is used. I have had my heater core replace 2 years ago and my radiator flushed. And now it is failing again. A service bulletin has been issued, so Ford knows about the problem. Why am I left holding the bag for repairs on defective parts.
Engine coolant reservoir sprang a leak on the bottom side. There is about a 1-inch gap between the bottom of the bottle and the fender so rubbing against something was not the cause. I called a parts house who said they had replaced 3 of them in the past 2 weeks. Seems like an odd coincidence the bottles leak. I've never seen one leak on any car I've ever owned.
Smoke began coming out of vents when air conditioning was turned on. If I turned it off and waited a few minutes, the air conditioning would work again. This happened every time I tried to use the air conditioning. In September, when I tried using the heater, it did not work. I changed the thermostat and had engine cooling system flushed. However this still did not resolve my problem. I contacted my local Ford dealership,. They informed me that this a common problem with the 98 Taurus. The engine coolant Ford makes you use clogs the system and turns the coolant into sludge. The only thing you can do is to replace the heater core. They also stated that on average I will have to replace the heater core every other year. This is unacceptable.
