Yeah, that I planned on doing, though I think the Water pump and that knock sensor are at about the same level and I will usually pull the lower radiator hose to drain out extra coolant.

I used a wet dry vac last night on Drew's cooling system. Scotty you are probably right about the water pump. Drew was holding the vac (small craftsman wet/dry) while I hit the LIM/Tstat housing area and bottom opening of the radiator. When I got to the water pump and started to vacuum coolant from there. He and I were both amazed how much coolant was extracted.

Even with all the hoses removed? Did you pull the knock sensor?Originally Posted by IndeedSS
What was your process? Were you vacuuming from the Tstat housing and he was doing the same from the water pump? Give me some details, and when I get around to draining mine out I will see what I can come with. I definitely want to build something like Toasty posted though just to spare the poor Shop-Vac.

He was holding the vac because it is a smaller unit and the hose doesn't have much reach.
With the lower radiator hose, radiator cap, thermostat, and thermostat housing removed, I put the vac hose in each of the following loactions; the LIM tstat opening, upper radiator hose, lower radiator hose opening, and the directly to the water pump. I used a damp cloth wrapped around the vac hose to help seal the extraction points. I'm not going to pull the knock sensor, since it's not that important to me. Plus I would have to buy a 7/8 deep walled socket.
When we pull the alternator tonight I'll vacuum out those points as well.
The fluid collected looks to be about 2 - 2.5 gallons, not including what went all over the floor.
