2021 Ram Trx Ic cooling level low

[Swayse]

We get the message as well, and we’ve had a check engine light, that comes and goes. We watch the ic coolant temperature, I’ve caught it not working, hit a bump in the road and it starts working. It’s always on first start, once it goes it works fine all day. I’ll take it in soon, I’ve been putting it off for too long.

Dealership put a new I/C pump in my truck today. No more message upon ignition start.
*One note- my I/C coolant temp hit 152 degrees one day last week when I only drove 6 miles at 50mph. Truck idled a bit unusual that day too. It normally runs I/C temps between 60 and 80 degrees. So I would have to say, if you get the "I/C coolant level low " message then you should monitor your temperature on the performance page. I personally did not take any long trips until it was fixed, and after seeing 152 degrees that day, I'm glad I didnt.

Made an appointment to get the intercooler coolant pump replaced, and get the springs on the drivers side replaced as well, to fix the lean.

Hello, I have also gotten the same I/C level low light along with random CEL light on/off showing pump performance codes. I have taken to the dealer twice and they have just reset the codes. I have noticed that the i/c temp gauge is all over the place. Sometimes it will run 55-60 then randomly it will run 100-120 and the truck will idle funky. I shot a heat gun at the lines coming off the pump when it was reading 120. The lines were reading 75 degrees. Took back to the dealer and they replaced the i/c pump, did not fix the issue. They then changed the wiring harness, same issue. Now they are saying it is the computer. Waiting on that for a few weeks now. Hoping this resolves the issue. Any one else have the same issue and was the computer in fact bad?
