Questionown a 96 buick lesabra,would like to replace coolant without removing starter.I've removed lower radaitor hose and only get 1 gallon of fluid.would like to remove at least 2 gallons.Is there a simple way to deal with matter?
AnswerYou aren't going to get much more out of the block than you get out of the lower radiator hose.
You could pull a heater hose, return prefferably, and using a garden hose, flush some water back through the system that way. Then even blow on the heater hose to get more out.
When you fill the radiator with new coolant mix, leave the heater hose off, and start the engine. That way, the water pump will force coolant into the heater core, and push the plain water out.
