Yep. The Limited does not have a supercharger, and thus no intercooler pump to fail.

 

Just bought an SRT6 with 16,000 on it, I am now part of the Klan receiving the ever so annoying sluggish acceleration. They ran the DRB scan and found the temp sensor was bad so I decided to have it all replaced. I printed off the part numbers told them that was the problem if it wasn’t then I would pay for it out of pocket. I just wanted it fixed. I hope this fixes the problem. This car is a bullet when it wants to work. Have we decided for sure that this is going to fix this problem? Everyone who has had this fix is your SC working properly now. Second call me irresponsible but the best way I have found to duplicate the problem is when I hits about 100. Every time I have gunned it and it has decided to kick in, it will shut off at about 100. Hope that will help, now all you have to do is explain to the tech why you’re driving like an idiot.

 

Is the coolant system for the IC pump a separate closed loop for just the intercooler and not integrated into the main cooling system? (i.e. does a leak in that system affect the main engine coolant level?).

It appears to take engine coolant for the IC exchanger. Someone confirm this?

 

Yes, this is true. Both units share the same reservoir.

 

Thanks Rydiak!

Are these pumps supposed to run continuously when the engine is running?
or
Are they thermostatically controlled by a temperature sensor?

Do they run for 5-20 seconds AFTER the engine is shut down like the C32/SLK32 AMG pumps supposedly do? Anyone with a known good pump (recently replaced) hear the pump run after engine shut down? If so, we may have a simple diagnostic tool.

 

Anyone do a failure analysis of a bad IC aux. pump? Does the motor winding open up? (i.e. infinite resistance across the terminals?).

OR are they freezing up/breaking mechanically?

 

Well, the sluggish acceleration syndrome has struck my SRT6. Happened yesterday on my way up from the Keys. It would come and go. There was no rhyme or reason.

The dealer has yet to determine why the other Xfire is having the SA.

I think I will call Chrysler Tech.

 

hey rmaderman, when you get yours fixed, can you please tell me what dealer in S. FL. to take mine to. i have already taken mine to Maroone Chrysler Coconut Creek and they couldn't diagnose it (of course). they also have never heard of any IC pump issues.

 

I will let you know.

 

IF the failure mode on these IC aux. pumps is the motor winding opening up, this should be a straightforward diagnosis: a resistance check of the motor winding from the terminals on the pump while disconnected. This ain't rocket science. The trick is to get them to believe the pump is most likely the problem and do the check. Charge temperature variation is most likely the reason for the intermittent nature of the failure.

 

So has anyone resoved this problem yet, I'm now having the same problem.

 

The ones who have had their aux. IC coolant pumps replaced have mostly all resolved this problem. This thread has many anecdotal repair stories. As far as a better pump, I don't know if Bosch has improved it's design/construction of the unit.

 

Ok cool will get it taken care of, thanks for the info.

 

Dropped off my SRT6 @ the dealer this afternoon. Had the service manger go with me for a ride and presto, I had no acceleration. He was nonchalant and I think dumbfounded about it and said he would have call Chrysler technical to find out more about this problem. This after I gave him prinouts describing the problem as being the IC pump. He said the one P code that printed out was for a water pump.

Anyways, I told him to order two of whatever he thinks will fix the problem cause my daughters Xfire has the same problem. It just is not happening as frequently as mine has been. Plus my top is not working on command. That is probably the switch, even though it lights up. Or it might be the connection in the truck. Time will tell.

I asked my service manger if he thought I could have it back by Friday. The other service rep started laughing. I really came close to showing him that I could still do a nice roundhouse to his head while he was sitting on his stool. But, I just smiled and told my rep to do his best.

 

Just give him a swift kick to the head, and tell him to replace the I/C pump! I had the same problem, but I bought my car from a huge Chrysler dealer here in Minn, and in return knew how to fix the problem...

 

unfortunately my i/c pump woes have failed to be discovered and/or fixed by two different dealers. i asked a few months ago if i should even bother to fix the problem since my lease was coming due at the end of october and the car was to be returned. most of you on the board told me to do the right thing and fix it for the next owner and i tried but, oh well...it is really sad because for the first two plus years i had nothing but positive experiences with the car and truly "loved" my car. the last six months have effectively ruined it for me between the constant loss of power on the highway (i drive 40 miles a day of highway only driving) and the dealer(s) lack of ability to diagnose and fix an ongoing problem. i wish all of you with this problem good luck as i, thankfully, only have to deal with it for a few more weeks.

 

Drive to IL and I'll fix it for you in my garage. It is literally one of the easiest automotive repairs you can do.

 

Ok, I have 2 srt6's my convertible seem much more peppy then my coupe, the coupe does drive sluggishly, but I don't know if its the pump or not? When I do press on the gas it moves pretty quickly, but with everyday driving it seems more sluggish then my other srt6, what should I do? Tell the dealer to replace the pump anyway? Also how long can I expect the new pump to work for? What's the life expectancy of the pump and the supercharger???

 

When I use the term "sluggish Acceleration", No Acceleration would probably be more of a correct term. If you floor the car it just ever so slightly increases the speed, although the rpm's increase dramatically. The dealer kept insisting the problem was the trans. I was the IC pump. They were replaced in both SRT's.

My SRT has a bit better acceleration then my daughter's SRT. It just seems stronger. It was like that before I put the sprint booster in mine. She gets better gas mpg then I do though.

 

I've only had my srt 1 month and it already has 2,500 mile and I have noticed a few times a hic-cup sluggish acceleration is this a bad pump already?
