Chunky Brown Sludge in Coolant Tank...

[violametallic-S-]

Ordered the oil cooler and seals 250 from the dealer not bad. If someone has experienced this issue, could you tell what kind of product you used to clean out the cooling system? I dont think water will help with the caked on gunk inside the tank.

Prestone cooling system cleaner, then lots of clear water............

And I really would not put dishwasher detergent in one of these systems.

JFP, the Prestone super flush works great and after flushing with clean water a few times I also like to add the Prestone additive (lubricant..?) to the distilled water and antifreeze mix to neutralize the acid from the super flush.
