  1. Thank you guys so much (rockfangd & Texas Jim) but KHE was right. The pellets actually clogged all circulation through the system. I removed the hose leading to the radiator, poured coolant into it, burping it in between and reconnected the hose back to the engine. Then I turned it on along with the heater on full blast at 90° and poured the remaining antifreeze coolant into the reservoir tank. After running the engine for 5 minutes, I noticed the temperature only rose to about 201°! She's been running GREAT ever since! Thank you so much for the help! GOD BLESS Y'ALL!!!
  2. I have a 1996 Cadillac DeVille Concour Sedan with a 4.6 Liter 8 Cylinder Northstar Engine that has 74,389 miles on it. Recently, it started leaking coolant approximately under the front center of the car. I applied a product called BARS LEAKS RADIATOR HEAVY DUTY LEAKS additive and it worked for about two months. The problem arised again recently and I did the same thing but the results was unsuccessful. The tank had become half filled with these pellets and now the coolant is leaking at a much faster rate then before. I was wondering if there is a way to replace the leading tube on the bottom to keep the cost down or if I have to replace the entire system all together? I have low a/c compressor readings when I try to turn the fan on to keep it from overheating while I'm driving but that fails. The highest temperature ever recorded while driving is 258°. It still purrs like a cat without any engine noise but I noticed that more coolant LEAKS out when it's in idle. Can someone Please help me? I don't want to have to sell HER.
