Drop off my 03 cl55 yesterday at the dealer.. told them she was not running strong !! so they called me back today told me the secondary pump is no good.. my question is the secondary pump the same as the intercooler pump ??? thanks

 

Secondary pump? I've never heard of a secondary pump. But they should be more specific in telling you exactly what pump has to be replaced. Be sure to ask them if the secondary pump refers to the IC pump. Most likely it does but just ask to be sure.

 

yes ic pump. If not working, IAT will rise and cut boost=no powa.

 

got my car back !!! she feels so strong !! secondary pump is aka ic pump at the dealer... they replace the pump and sc pulley !! she is running like new again..

 

Very good. have fun and be safe !!

 

I just replaced mine last week, and it makes a huge difference. Fortunately it is an easy job and only took me about an hour.

 

Dino,

I assume you changed the pump on your SL. Could you please post instructions on how you did it ? I am sure others would like to know.

Thanks,
Lou
