LoyaleFan

The heater core is what makes the most sense...My brother was driving at the time of failure, so I didn't check the temp gauge, but, from what I understand, overheating can cause loss of power. Correct? I started it up cold and was able to pull up the driveway. So...this leads me to think that it is the heater core that has gone bad. Thank you for your input. Chris.

What's wrong with my 1992 Loyale? Here are the symptoms: I pulled into my driveway this morning and didn't have enough power to make it the entire way up (it's less than a 6% grade). I'm very slowly losing coolant. I also noticed that I had tiny brown spots on the inside of my windshield. Brown, because I added "Bars Leaks" to stop my slow coolant loss (that was about 300 miles ago, or 1 week). The spark plugs were not wet, but they were slightly fouled. I don't have moisture on my floor, so, I'm not sure if it would be the Heater Core or not. Any help would be great. Thanks. Chris.
