Cooliant system filled with slugs caused by dex coolant product. Breakdown. Dex is suppose to be good for 100,000 miles, at 53,000 took vehicle in for tranmission hose leak, dealer opened radiator cap and said this is a on going problem with Blazer. Recommended a flush be done, which the dealership did. Now vehicle has an indication (spike) of over heating. Now dealership states block needs to be pulled, freeze plugs pulled and a complete block flush, along with radiator recored and heater core replaced. Is there any information on the breakdown of dex coolant fuilds that is causing this problem or that has been sent out from the manufacter of this product. I am now looking at $1,300 of repairs to correct this problem.

Contamination of cooling system due to dex-cool. Entire system must be flushed and heater core replaced. Chevrolet motor div. Has offered to pay for half the cost, although it is no longer under their 36,000 mile warranty. My concern is that there is a major problem with dex-cool and they are not responding to it, as they claim that it should not need to be changed for 5 years or 150,000 miles. I found out about the contamination after bringing my car in for a sloshing, gurgling sound under the dash.
