Re: 01 Eldo Coolant changing tips
50/50 is the proper mix. Lower hose is hard to get at. That's why I put the tabs in the upper. Not hard to find someone who will take used oil but I have found it almost impossible to get rid of coolant.
There's a Pennzoil oil change place near my house, and they also do coolant changes... They will take your used coolant. For some reason, they are adament that they do NOT want the containers... they pour the jugs in their waste tank, and give me back the empty jugs....
As for the coolant tabs, I pre-dissolved them, as the original post stated, and poured that mix in the overflow bottle... worked out fine. Pre-dissolved in the FIRST HALF GALLON that I added, and then "chased it down" with pure 50/50 mix....
Yes, I did the petcock. Takes awhile, but it works, and it's pretty easy. Lowering the car off the jack will get more coolant out... I pretty much did exactly what's in the original post.
As far as possibly not getting "all" the coolant out, my intention is to do it again in fall.... probably overkill, but it only cost $20-some bucks to do it myself.... costs me $15 in gas to go to work... so, make of it what you will, $20 to be sure I'm good seems like cheap insurance.....
How did you derive at 5 1/16 " long on the dowel. That seems pretty precise. Why would there be a length problem here. Wouldn't 6" have been fine? I'm going out to do this today but I also got a 3/4 dowel rather than 7/8 because I thought I read that. I guess it will still work.
