I decided to test on my Sundance DD as the cooling system crackles after driving and I can hear things boil slightly.
Now the problem...
This product caused my rad fan to stop working even on an 85 degree day, idling in my driveway. And it also busted my temperature gauge, WTF
I have checked relays and fan motor etc but i am out of ideas......
Now I need help to fix my fan ....any suggestions????
On a serious note, the product worked great and the rad fan is fine, Thanks Craig for the suggestion, I did pick up 5 jugs from Walmart in the USA a few week back.
It really did help the cooling system
