Northern Alberta | My brother, 35 year HD mechanic uses sunlight dish soap. Dawn would be good also. He has never said anything about removing the 'stat or blocking the rad. I would think you would ANT it to circulate through the rad as it will have oil in it also. As far as bubbles go, you are a farmer, you should have some de-foamer for your sprayer around. Use that for the flush cycles. | |
