I have started and ran mine in negative 35 with no problems...I only run non bio fuel and put additives in and that makes the difference...stop using bio blended fuel if you can
I did this to perfectly level my 2006 Silverado....passenger rear was 3/4 inch higher....took 220 lbs. of concrete bags...been sitting there for 13 years now....wrapped it tightly in black duct tape to blend in with black truck...hardly notice it. Stack it behind the wheel well so it doesn't move around...its only moved a couple of times when I really had to brake hard.
The suction hose in my 2950 is just cut off, no connector, therefore I don't need to cut the tops off the bottles. You didn't mention turning the water pump bypass again before closing up the panel, I clear the antifreeze the same way as the water. You also only used one bottle of antifreeze and didn't explain why you needed 3 or 4 bottles.
God Bless you all! All glory to God! Turn from your sins and live for God! Romans 10:9 “if you declare with your mouth that Jesus is Lord and believe in your heart that God rose Him from the dead you will be saved.”
