I have a 2010 connect and I’m having problems with the coolant reservoir. I’ve replaced it twice now because the cap keeps loosing up or pops up slightly because of the pressure. I can smell it inside of the van. Tonight I notice that there was a pretty big leak. It looks to be coming from the cap. And I can see the coolant bubbling in the reservoir.
New cap and tank. As far as. Can tell the van isn’t over heating. No mixing of oil and coolant. And I travel over two hundred miles ever week.
It it just seems like the cap isn’t holding pressure. But I’ve also tried a different cap. But if you tighten it up it mess up the threads and you need a new tank.
Many help or suggestions would be greatly appreciated
