1FASTC32's Cheep Intercooler Pump Replacement
#76
ok, got my pump today, going to replace it over the weekend. couple of questions first though, when i disconnect the hoses from the old pump, how much coolant is going to flow out? all of it? also what type of coolant do i need to refill it with, and whats the proper procedure for putting the pump back on, as in i install the new pump, and start the car and let the fluid run through it? or what? any help is greatly appreciated. thanks

you will lose quite a bit of coolant, just refill the plastic fill tank when you get the new pump installed and start the car and let it run...the fluid will begin to drop down and you can monitor it and keep filling it back up until the fluid level does not drop down anymore...the car's monitoring system will also tell you if the coolant is low

Doesn't coolant also have properties that help it keep cooler, or cool faster than just water?...maybe that's what the Redline stuff is?...never heard of that.

Yeah because those parts are holding up well with the MB coolant in them ![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)

Seems like a bunch of intercooler pumps failed all at the same time, about when it started to warm up. This should be a recall item.
Speaking of which, (not hijacking, just a question)... did anyone have any problems with their air pump whateverthingie before the most recent service campaign?
Didn't think so.
Interesting that with all the mechanical/electrical defects this car has, MB chose to replace that part?

Ummmm......Yes.
The air pump is also a chronic problem.

What are the symptoms of air-relay pump failure? With all the stuff gone wrong on this POS, it's hard to distinguish one issue from another.

BTW, why are people replacing their water pumps if their OEM Bosch water pump is still working and there are no power loss symtoms.

I don't think there are any performance advantages other than this is a much cheaper alternative to the OEM part, and can be an easy DIY fix. Anyways, thanks for the useful info and pics.

I think I'm going to go ahead and do this too. After I took it in for the recall, I dont hear my pump stay on anymore when I shut off the car...it used to be noticeable and run for a few seconds after I shut off the car. The car also doesnt feel as responsive or strong. I should give this a try, although I wished I knew why it stopped working after the relay recall.
Where did you guys buy your pumps? Diversified products or eBay?
Do I need anything else besides the new pump, MB coolant, and crimp connectors. Is one bottle of coolant enough?...not quite sure how they sell it at the dealership. And what gauge wire are the two wires?
Thanks!

I'm not the most mechanically inclined person around. In addition to the wire, spade connectors, and liquid tape, what tools will I need? Someone mentioned vice-grips to remove the hose clamps. Anything else?
