I have a 2000 Chevy Monte Carlo with the 3.4L motor. 36K miles. Took it to the dealer today under waranty for an intermittent low coolant light. With all the problems with intake manifolds...I thought a pressure test was in order. Pressure tested fine ....held for 45 minutes (so I was told) Mechanic said that the light was caused by the "mud" as he called it that has formed inside the radiator. The dealer said that this was caused by either a slow air leak in the system (which is what the pressure check SHOULD have found) or someone added something to the Dex-Cool that caused the "mud"
They wanted to flush my system....(for $99.99) but the warranty did not cover that type of maintenance.....
SO my question is what is the best thing to flush a Dex-Cool system with? I have flushed ethylene-glycol systems with Prestone with no troubles. Is there a specific type of flush I need to get rid of the mud? Is there any odd thing that I should know about flushing this car that may be different from the other systems I have done in the past??
Thanks in advance for the help, and the abuse.....I live for it!! But do not be suprised if I fire back ;-)
