Hi Smarties...

Only 2.5 weeks old here :D. Am approaching 40,000 miles on my "new to me" 2009 Passion and am ready to tackle the 40K maintenance. Am pretty handy and well versed in things mechanical; however don't have a shop manual; cannot find one! The only major service now is coolant change besides the oil/filter change.

Planning to do a coolant/flush, etc. So from where do you drain it from(radiator petcock?) and to where do you fill the new coolant(expansion bowl?) and at what glycol/water % mix? Then you gotta "burp" her..right.?.IS there a procedure for the burping??

Thank you..

Cheers...

As always...Thank you... jwight...and the rest who wanted to chime in but our Bohemian Moderator was zu schnell, wasn't he? :D.

Curious !?..we can use the block drain procedure Evilution uses ? instead of the hose "burp", right IF we have that Allen drain plug. Haven't looked for it yet...engine too hot now...

Cheers...

Coolant change/flush..AGAIN!!

Hi All..

Another coolant change subject, ahem..!:(..BUT..after going through all the motions here regarding coolants, Evilution, WIS, etc...it seem that the coolant after removing the expansion cap can be totally emptied by just opening the block screw which is lower than the lower radiator hose! This will drain the ENTIRE coolant entirely?? Then one doesn't have to mess with accessing the lower radiator hose. OF course will one have to "burp" at the end of the coolant change at the block head!

What say you :cool:?

cheers...

could you clamp off the lower hose and drain and refill the radiator to do a change out.
The lower hose of the radiator is a pain in the arse to get to in my '09 Passion; have to remove the front underneath splash/stone chip panel(whatever you call it). To all my researches I agree with Evilution that you only have to open/remove the engine block coolant drain if you have one..slowly at first by just cracking the expansion tanks cap then open thecap fully for a streaming out flow! This engine block drain plug is at it's lowest then why not..gravity!!? Then close it...remove the header coolant hose; fill the expansion tank with your chosen stuff....once you see it come out of the header coolant hose: you got it "burped"...clamp hosefill expansion tank to min-max mark. Run motor...check coolant make level.

Please chime in..is this right ? or am I dreamin' .:)

cheers...

I don't believe you will get it all out that way. If you look at a diagram of how the hoses are run from the front of the car, they raise up to the front of the block after they come out of the body. Therefore, it will puddle in the hoses, and you will still have probably 1/2 a gallon of the old stuff still in the system. Will that hurt anything? Probably not, but if you want to completely drain it, you're going to have to pull the hose.

I also looked at the drain bolt. It looks like it will be a pain to get out. but you could do a controlled drain and refill of the tank if you do not car to leave some old stuff in there.

2009 Passion(451) Coolant Dance..

Hi All..

Many thanks for your input.

While our Northern Brethrens are battening down their Smarties due to TS/Hurr. SANDY.......Sandy is to skirt my State :D so took the liberty in doing my first coolant dance in my garage!

1) Locate the lower radiator drain hose; right front fender; under the panel..

************

Remove 2 of these screws; one on each side



Drop the panel and weigh it down with !!!



Locate hose clamp..unclamp; remove hose(whew)..drain coolant



Already had ss clamp attached; previous owner obviously had coolant changed at one time.



Open engine block bolt and drain...



Reclamp radiator hose and reattach underbody panel; reinsert engine block drain bolt and tighten.

****************************************

Position one way valve out of the way for access to header hose.



Locate header hose and unclamp..



Remove hose and have SWMBO pour..... >



into radiator expansion tank...observe coolant coming out of header nipple; reinsert header hose and clamp...It's been "burped"..:cool:.

Fill the rest of the coolant till MAX mark. Go for test drive...check level..add if necessary.

Now: manual says that my system holds 4.5 qts = 4.3l, but I could only add 4 qts=3.78l. I believe I drained the old coolant completely unless the water pump retained some! Now I am 0.5 qts short...cause for worry...air still there??

Expansion tank is at MAX level. Will sink below MAX overnight when coolant cools...add more to attain MAX ???

I did the procedure "cold"....was not running the engine when "burping", just bled the system cold!

cheers...

Nicely done. Good photos and detailed process. You may be new here but you have a future in the asylum. :bigthumbup:

Regards,

Dan
Thank you guys for all the "Thanks"...By the way I could really be more specifically detailed in regard to photos but found out that you can post only 10 images..gggrrrrr. Hmmnnn; WHY! Coming from ADVrider.com I could post images with abandon . Now could I post 10 images per post, and call it Coolant-1; Coolant-2 :D= 20 images??

You guys need to answer my querry regarding the 0.5 qts shortage..any worries:eek:.

Brakes are next..:cool:.

cheers...
