Yes, i used water weter n thought of that so i put 50/50 water/ coolant in a milk jug and added water weter ,it blended right in,but thats a good call thanks for ur reply i live in florida it was around 90 today heat could be a factor (under what tempatures have u seen that stuff bead) and i have installed a new water pump/ raidator without a flush but the pump should have a seald baring n the rad was sealed off at the conectors with caps
