would this work, if not please explain why

I believe my car still has the original coolant and I would feel a lot better knowing it was changed. If I were to put the front end up on ramps so the rear end is lower then opened the resivour cap and heater valve then removed the engine plug wouldn't the antifreeze all drain out by gravity?

Physically I cannot get up and down several times nor can I afford a shop labor rate (probably couple of hours at flat rate time)

thank you for your input

From what I have read on this forum, draining isn't the problem. Refilling and bleeding the system, that's the tricky part.
I'm willing to bet there are more than few blown head gaskets, from overheating because of an improperly bled cooling system.

Remember that's a lot of plumbing from the engine in the rear through heater core, radiator and back to the engine. Something like 15 feet of pipe and hose or more.
Sounds like a using a pump to push the new coolant through the system kind of like embalming the car would work best. When you turn the water in a hose that's been partially drained and you get the spuddering sound as the air is being forced out by the water.

Good luck with this endeavor.

bleeding the air out of the system is not as bad as it sounds. the hose you need to remove is at the top of the motor, the tough part is draining the coolant.
I have heard horror stories about flushing the coolant on older cars, how it has caused debris to break loose and plug heater cores and such. Probably won't happen on a newer car but in my opinion, why take a chance. And they do charge a bit for the service. ifyou do go that route, I'd stay away from the fancy additives to clean the system, etc.

I do know what you mean about getting down and up too many times.... I need one of these myself...
