1994 Chrysler LHS Overheating
1994 Chrysler LHS 6 cyl Two Wheel Drive Automatic 160K miles
1994 lhs overheating, it started after an oil/water pump/thermostat/ change 2 months ago. since then i have had to constantly add water (coolant would have been to expensive) and a quart of oil on 2 occasions. the temp gauge usually read at the middle mark (it used to run at the quarter mark) but never over heated until yesterday. fan and fuses are fine, no smoke from exhaust. the engine has been making a rattling noise for the past month but i dont notice a loss of power
thanks you

First, if the water pump was replaced, I would go back to the person who did the work for you. If there is a leak (after the work) something was done wrong. Also, remember, coolant not only prevents freezing, but also has a much higher boiling point than water as well as it lubericates the water pump and helps stop corrosion. For example:
Water: Freeze 32F Boil 212F
50/50 coolant: Freeze -45F Boil 270F
THerefore, I recomend locating the leak. Place cardboard under the car where it is parked so you can identify the area where the leak is coming from. Let me know what you find.
As far as the ratteling noise. Could it be coming from under the car? Could it be a heat shield or the internal parts of the catylatic converter? A plugging converter will cause a loss of power and the engine to run hot. Drive the car at night and check the converter to see if it glows red. If so, it's plugging.
