Muddy, Muddy, Muddy
Dude, you kill me!
Change your coolant. Use the right concentration. Do not use an electric element in your cooling system to aid in warm-up. Too much juice required for your alternator to handle it (1000 - 1500 Watts), and the possibility that the cooling system can come in contact with electrical current. This contact can form pinhole leaks in the cooling system, same as if you have unprotected wiring harnesses in contact with your cooling components.
