Sounds like its a Bosch pump, like the OEM. Await the specifics from the SL forum with interest.

very common with the C32

infact they are also using Cobra IC HE, very cheap around $300.


Bosche makes pumps for everybody, including Ford.

Thanks for the links

Um quick question

I recall reading that the Bosch pump was failing mostly due to some bad motor they had in the unit.
Now does this cobra pump have this same motor? if so won't the problem of pump failing happen again

cheers
Khalid

pump! (sorry had to say it )
I mean bump

come on guys what think thee of this pump?
There has been an update on the SL forum

can this pump be seen as a middle man between cm90 and cm30. As people said cm90 is overkill and that it might cause problems because flow could be to high to cool things?

right came across this thread while searching. Not sure how much it holds relevance, but it has pics!!

http://www.f150online.com/forums/sho...d.php?t=139146

check page 1 & 5 also has comments by a person claiming to be one of the designers

am still confused on the cobra pump and if it is the same one mentioned on the SL forum. IF it is still not sure it its better or not then stock or johson cm30

Those f150 guys are talking about the coolant pump for the radiator which, I assume, is driven off the crankshaft. So a larger pump flows more water but because its bigger saps more energy from the engine.

The intercooler pump in the E55 is electric and not crank driven. A bigger pump doesn't sap anymore crank power - because its not connected to the crank. A bigger pump, the 90, is just harder to fit because of its size and the hose fittings.

Thats my take anyway.
