Leaking Coolant?

Anyone else notice issues with their coolant levels being low? I popped the hood the other day to find my coolant levels 2 inches below the minimum threshold line. Brought it in today to the dealer and was told that a part was leaking, cant remember what it was for the life of me and that it needs to stay in the shop for warranty work. I will be in the dealership tomorrow to get the details on what the issue is but wondering if anyone has had any issues around this with their Pacifica's. Mine has only 4,000km on it!

Did you notice any coolant on the ground where you normally park? I too noticed the coolant level was low shortly after I purchased it, but once I topped it off it hasn't gone down since. I attribute it to them not fully burping out the air bubbles when they filled it at the factory.

I had the radiator replaced on my 2017 Pacifica Touring L at 21,000 miles after a very small coolant leak was found. The coolant level would take months to get to a lower level in the tank. Now a year and a half later it is happening again. Bought more 50/50 mopar coolant at a dealer and asked him if the radiator was a common part to replace. The parts person looked it up on his computer and said about 60 a month were sold by Chrysler. Guess it time time to take it in and use my Mopar Lifetime warranty as the mileage is now at 43,000 miles.

We're at around 78k with our Touring L and also have coolant "disappearing" someplace. We were down below the lowest line on the reservoir, and so I refilled the coolant two weeks ago and it's holding steady. I can't see any obvious leaks or sprays of coolant from a leaking radiator, which I'm familiar with from a previous car. I'm a bit nervous that it could be leaking someplace else.

Not sure if it's related, but we also have a gurgling sound behind the dash - not audible from outside the car, or from engine compartment. The electronic coolant temp meter in the Pacifica's computer doesn't indicate anything terribly high - with my latest addition of coolant, or even when it was low.

I'm not sure if I'm reading this right, this thread is 4 years old and you have a '17 with 78k miles on it, so you did those miles in 1 year?

I know this is an old thread but did you ever get your problem figured out? My '18 with 60k miles seems to always use about a half inch of coolant every couple of thousand miles with absolutely no leaks so just wondering
if everybody's coolant is going down to a little.:rolleyes:

So apparently it sounds like it was the EGR Valve that attaches to the engine? I had not seen any leaks on the driveway and they mentioned it was a slow leak, but that it should not being doing this. They wondered if the coolant was evaporating which is why we never saw or smelt anything?? Seems odd. Anyway the part is on backorder so who knows how long this will take. Pretty ticked that this is happening to a vehicle that had literally less than 2500 miles on it. So incredibly frustrating.

2017 with 26k and I've also had to top off fluid. Still keeping an eye on it and wondering if the dealer is going to give me a hard time to determine and fix the issue. I've been avoiding going until there is evident they can't ignore.

Did you ever get this fixed? Was it the EGR cooler that was leaking?

Wow, I suppose we should expect to see more of these in the future. EGR coolers have been around on diesel engines for over 15 years now, they exist to cool the exhaust gas before being fed back into the intake manifold. It’s an emissions tool, and cooling the gas allows them to increase efficiency. They are known failure point in diesel engines of all varieties, but not terribly problematic in most cases.

I had a leaky coolant line under the van that almost left me stranded, but that’s completely unrelated to your issue. I hope they at least put you in a nice loner.

I'm in a Dodge Durango, but still not the same as our Pacifica :(

I noticed my coolant was an inch or two low as well - only 20k mi and no smell nor visible leaks on the ground. I bought some OEM fluid and we'll see if it continues to go down over time

I'm currently helping my sister-in-law shop for a used Pacifica, and I'm noticing this a lot in the underhood pictures.

My 2021 smells like coolant. Was about 1/2 inch below full on the overflow tank. I topped it off two weeks ago, didnt seem to disappear yet. But the smell lingers in the garage everyday. Had this same issue with my 2018 caravan, it turned out be a pin hole in the drivers side of the radiator down very low. Took me forever to find it.

When the engine's hot and full of pressure pop the hood with a flashlight and look down deep and see if you can see any wet areas is a good start. I've watched some videos where these new pacificas get pin holes in the radiator. Check the coolant recovery Bottle too sometimes those hose connections aren't tight and it leaks from up there too I also check around the alternator area where the water pump is to see if the water pump is leaking. With a '21 I would think not but you have to look at everything

Exactly, where it connects to the aluminum tube. I added extra zip ties and it's almost gone now.
From the bottom of the engine, there were leaks of coolant on the electric cubes. Unfortunately, I didn't take a picture then.

Yes I will definitely keep an eye on that area I can see where you put the radiator clamps on glad it helped... Did you visibly see coolant leaks coming from those areas or you just did that as a precaution and it worked?

Yes, you could see the pink liquid on the joint was wet. I did it so quickly, but it would be best to drain the fluid and put on some decent twist bands.
I think the diameter of the hose is too large or the clamp is not tight enough. (the hose turns very easily)
It's still leaking a bit, but I've noticed less fluid loss.
My pacifica had a front collision. They were replaced with new coolers. I don't think it had anything to do with this leak.

If coolant is getting into the block, the obvious suspect is a blown head gasket. If coolant level got so low that the engine overheated, the dealer might recommend a new engine.
