Well last year I started to have some overheating problems. I have ended up replacing the water pump, t-stat, Radiator, Radiator cap and radiator hoses. Even changing back to stock tune and cutting the cat out. But the heating still remains. On 100+ days after about 15 minutes of driving it will get up to 230 running empty and I cant even pull a trailer anymore. When I recently replaced the radiator and hoses I noticed a white grime on in the radiator and the hoses. I'm not sure if this evidence of electrolysis but I think it is. I have a picture of the inside of the hoses.
