The IC pump pushes coolant through a closed system correct?

The Coolant recovery tank and the radiator are not attached to the intercooler in any way?

I am going to change my IC pump. How do I re-fill the system if I spill some coolant during the change?

Seems to me people in warm states should use waterwetter and water alone in the system.

from the resovior on the right side ( driver side ) where it is written on the cap, coolant water, it has the same water ( sharing )

but bleede it by romving the cover out of the nipple ( left to the S/C pully ) untill water is coming out while the engine is runing.


you may need to do the bleeding again after a day or two.

The SL55 has it's reservoir on the passenger side.

So you are saying the coolant is shared between the two?

Yes they are. Most here separate them by adding a new reservoir and re-routing. I got the upgraded pump and an added HE, but somehow didn't get the separate reservoir that I was charged for.

If the coolant is shared then why do we have to bleed the system when installing a new IC pump? Why won't the air find it's way to the reservoir? Is there a two way value or something?

you can do it that way too.
i would do it both ways. the reservoir cap open way and the way mentioned in the pdf doc that i sent you.

Read this post and tell me your thoughts? It's about bleeding.

Apparently, there are spots in the Sc lines that form air pockets that may not be inline with the flow (which is scary in itself). That is why I hear of folks re-bleeding even after the dealer has done a flush and bleed. If so, I wonder if a mod is not in order to open up those "blind" spots. Wouldn't that also help with heat conduction?
