Default 2008 Grand Caravan coolant leak

Our 2008 Grand Caravan started to smell of evaporating coolant after a long drive of over an hour. Shorter drives didn't seem to matter, but when we stopped at backed-up intersections so the car had to idle, we would get steaming, but I couldn't get out to check it so drove on to destination and checked everything - smell but no leak. Coolant would get low after a few of these, but it wouldn't do this every time we made this trip. I finally put some stop-leak into the radiator. That seemed to work for awhile, but in short order it was doing this again. Now, however, there was a brown stain forming on the metal shield over the crossover exhaust pipe. I felt underneath of the water inlet housing where it connects to the engine and found a small drop of coolant. I pulled off the radiator hose and the water inlet housing to find the thermostat. The water inlet housing is made of thermoplastic with metal inserts for the bolts. The thermostat has a rubber gasket - the gasket was "blown" out (shredded - completely separated). The new thermostat came with the rubber gasket, but the gasket has a square appendage on it that has no place to go in the inlet housing, in fact, it makes the gasket not fit too well. I aligned it with the mark on the housing that puts the thermostat's vent at the top. After reassembling and refilling, I test drove successfully and since then the leak has been stopped. This type of thermostat gasket does not look much like a winner.

I'm suffering something very similar but no overheating yet as it just started. This is the best explanation I've found so far and I've seen a tiny drip at the bottom of the 'Y'.

the 'plastic' Y just above the exhaust manifold leaks when it gets hot and the manifold hides the evidence! cant wait for everyone to complain so dodge will give me my money back for an expensive but easy fix!

Welcome to DF
Do you know if the van is still covered under warranty? If it is, I would have the dealer fix it.

No it is not under warranty I purchased it used.

I can not get the house off it is like they are glued.

I found a universal T connector I just can not get the rubber tubing off.

have the same problem, however, the leak is much more severe. I can't get a hose clamp around the connection to reinforce, they are touching. The leak is coming from the lower connection that goes into the firewall, driver side. How do I disengage the hose from the valve? I've read that it is a quick connect fitting, though tugging on it doesn't remove it.... How do I get this hose off?

Thanks for your help!

I have the same problem. I've read all the same stuff about quick disconnect. The biotin line is you need to cut them off and buy all new hoses. I've been searching for weeks for the Y connector and new hoses. The only thing I've found was the inlet and outlet hoses that run 85.00.

You can only buy the hoses and tube together. There is no way around it. I have already tried.

Default coolant leak 2008 town and country

I had a pressure test done and no evidence of a leak. I finally found the Y above exhaust would leak ocasionally. The heat from exhuast would dry the line. i finally found the y dripping under certain circumstances. It around $15 to repair with aftermarket y from part store with new hose and hose clamps.

Where did you buy the "Y" tube? Any details on the process?

Hello to all. I have the same issue with the Y divert-er valve, it is leaking at the top part of that Y. It is so bad that it whistles after a short drive, and it is almost a guarantee that it will over heat if I put her on the highway. She is a 2008 Dodge Grand Caravan 3.3 L fuel flex SE.
So I went to a parts store and they told me that it is a dealer part. So I went to Dodge and found out that the part cost $90.00, cant remember what I paid for the coolant but it all came to $140.00. I feel good bout that. Not looking to go cheap on my family vehicle, plus Kadair32 kinda left us all in a loop $15.00 to get a aftermarket Y connector, no ifnfo on that and nothing on removing those hoses. SMH sorry I tried and they are a bitch to come off. I was told by a tech that you have to cut them and replace the whole thing with the new assembly. I will upload a pic later on tomorrow. Glad I found this place, Alldata installed and ready to go will document for you guys.

Part number: 04677603ak

Hello to all; Back again to report that I with the help of my brother in-law got it fixed, as you know I bought the part from Dodge, and this is what we did. Instead of changing out the entire tubing assembly that ran under and towards the back of the van, we cut open the rubber connecting points of the (Y) valve, from the old one, and carefully removed its counterpart from the new one. We then connected it all back, placed back all the clamps, and filled her up with the coolant. We over filled a bit but it went down after a few minutes of running her It was very easy to remove once I spliced them from the connecting points, easier than having to lift the van and getting under it to remove the entire assembly. Good luck I hope I have been helpful.

Default Replaced Y Connector with a T

I had the same problem so I replaced the Y connector with a T connector.
I also had to install brand new heater hose and clamps. Does anybody think this could be a problem? I attached a few pictures. Thanks

I bought a $11.00 part and fixed it myself. Its been a year now but I believe it was a Y connector and hoses off a equinox. I had to cut the hose from the new part to make it shorter but it fixed the leak.

Did this take care of the problem? And did the t connector effect how the heat worked. I have a 09 caravan but the same problem. PLEASE ADVISE

Default Replaced Y Connector with a T

Yes, it did solve the problem and the cooling system appears to be working properly, mine is a '10 Gran Caravan. I just went on a 3 hour road trip without any issues. However my concern is that the T connector diverts the water differently than a Y connector. I was hoping that an expert mechanic would reply with a comment.

This is exactly what I did Almost a year ago. It has held up fine, no more leaking.

the 2008 caravans also had a problem with the radiator caps being defective or wrong. I smelled antitfeeze when i bought mine new and it ended up being the radiator cap.
