Help-Intercooler Pump Problems

[Ralph]

I have a 2019 REWB (4,400 mi) and periodically I get the intercooler low warning after romping on the car and backing off. This began happening after I had the AC serviced by a local, trusted mechanic (not a dealer), but I think that this is just concidental. The coolant level is ok and the "check diagnostic code" shows ok or no codes. Driving around today and getting on the car a little bit, IC coolant temp rose to 130 after about 30 minutes on a 70 degree day here in Phoenix.

I have tried bleeding the air from the system using the "pinch the hose" technique and this seemed to worked for a while. However the problem soon returned. To make things worse, the first few times I tried this, I could see fluid pumping through the overflow tank. Now however, I don't see fluid flow and can't hear the pump running. I've checked the fuse and it is ok so I am thinking that somehow I burned up the pump.

I talked to the dealer today about getting it in but am really hesitant to bring it to them. They said that they would probably need the car overnight and would store it overnight on the back lot. So I am thinking about doing the job myself. I am also thinking about upgrading the pump with an aftermarket one if that is possible. Anyway if you folks have any tips, tricks, advice, etc. that might help, I would really appreciate any information that you might have. Thanks

Let the dealer do it. Make sure they have the pump on hand before you drop it off. Shouldn't take more than a few hours and you don't have to leave it overnight. I wouldn't do that.

Thanks, that's what I will probably do.

Yeah, I agree. A friend of mine left his Lexus suv at a dealership near this Dodge dealer and it was stolen off the lot. If that's not bad enough, took them a couple of days to admit they no longer had the Lexus

Can you hear the pump run if you just key on and don’t start the vehicle? It should run for about 15 to 30 seconds. When you had your car worked on was the coolant drained from the intercooler loop?

I've tried to listen for the pump but don't hear anything, my hearing isn't what it was, but during that 15 to 30, I don't see any fluid motion in the fill tank. As for the coolant being drained from the intercooler loop, I am not aware that they touched the intercooler at all. The service was to fill the freon and check for freon leaks. Thanks for the help

The pump runs at a reduced speed at idle and on Keon. It’s very faint sound and not enough volume to see any motion through the tank unless you pinched the main line and forced the flow through the tank. Did you try and see if there’s an air pocket caught up in the manifold on the back of the supercharger? There’s a bleeder valve on the top when the car is running open the bleeder valve a bit (7mm socket) and see if fluid is pushed out or not. You’ll then know if it’s under pressure or not (from flow) and if any air is caught there, it will be expelled.

Do you have a vac tool? I’ve had to put that on to get bubbles out before.

If your pump was bad I’d expect a code
