So I overheated the other day cus water boiled in my overflow container and popped the top off and I lost a bunch of water. But I stick my finger in the radiator and it felt all slimy. I couldn't really pull anything out but it was slimy. Should I use like Prestone radiator flush or something like that and flush it out? I can't use my water cus I'm on a well with a lot of minerals

 

Was it oily slimey? Examine the coolant closer, if it has oil in it you just fried your head gasket....

drain it and flush water through the system and see if it eventually runs clear. Make sure your oil levels are good before you do this.

 

Ya since I overheated I flushed and drained everything. But if I lifted the red tab on my radiator bubbles would come rushing out of my over flow container cus it was letting in air. So new cap and I put in a thermostat that opens at 180 degrees to keep it cool

 

i wanted to add, go to Walmart and buy 2 or 3 jugs of distilled water and flush it out really good, then mix water with antfreeze at a50/50 mix and refill. Check coolant after you drive it for a few miles and make sure it is still clear.

 

Ya I did that and I'm also running something called wetter wet which is AWESOME

 

Tide or any other powder detergent works really good at cleaning cooling systems. I use it in everything.
