1. Drain and refill with water and add a scoop or two of dishwasher detergent. This will clean out any grease and oil that might have made it's way into the cooling system.


2. Get a bottle of Thermocure, follow the instructions on the bottle. You won't believe how clean this will get your cooling system.



3. Refill with 50/50 conventional green antifreeze and leave your rust problems in the past.

So Ryan,

With the dishwasher detergant in the system...do you start the car and let the mixture do its thing?
