Question
QUESTION: Where can I buy a filling aid funnel for my 2000 300M coolant service.

ANSWER: An auto parts store should have one  its just a  funnel that will allow the water to be higher then the system so when an air bubble is present it will burp it out.

QUESTION: Should I just use a small vise grip plier to crimp off the hose? Then when the funnel is all of the way filled up release the vise. I know all about bleeding the system with the clear tubing I am asking about after I get a good stream out of the bleeder and shut off the bleeder. Do I keep filling up ther fullen to the top?

Answer
U might haft to do that with the bleed screw a few times once the engine is running and the thermostat is open up. The funnels I use seal off the up of the over flow tank so I can just keep the coolant in there and not have an issue with it spilling over and such. Mine is 40 bucks  but mine is a pro one  I could get one if u want for around 10 to 20  at a parts store its called a no spill funnel.
