I have a Crossfire SRT6 and have been told by the dealer that the intercooler pump needs replacing. We have had the car from new 2007 and its only done 35k. We replaced the intercooler at a cost of $6K and they now want to charge me another $2k to change the intercooler pump. I feel ripped off and have checked on the internet to see what I can buy a pump for and it would appear that they are about $200 for a Johnson CM30 intercooler pump. Does anyone know if this is the correct pump and how difficult is it to replace it yourself? I really don't like to feel ripped off so any help would be greatly appreciated (pictures would be an absolute bonus!)
