Why do I smell antifreeze inside and out of my van?

(2010 Chrysler Town & Country)
I smell antifreeze after car has been running and stops or gets shut off. The smell is inside and out around hood. I can smell it standing by each front tire well. There are no visible leaks anywhere inside or out and we have changed the thermostat. The temperature gauge also stays at half way as it always has when warmed up. Thank you!

You may have a small enough leak that evaporates before it reaches the ground. And the anti freeze evaporating is what you are smelling. You should have your cooling system pressure tested for leaks before the problem escalates into something worse.

Thank you for replying. We are going to have it looked at and hopefully its something minor and easily fixable. Fingers crossed!

Hi kmwmac,

There are many reasons this could happen. If there are no obvious signs of leaks on the ground, the best option would be to bring the van to a shop you trust and have them perform some diagnostic testing on the coolant system. Sometimes by just having the van on a lift and knowing the common issues to look for may be enough to figure it out. If the cause is not obvious at that point, the shop may need to perform tests such as a coolant system pressure test, combustion gas test, coolant flow test, etc.

We have seen many problems with the coolant tubes on these vans rotting out and starting as a slow leak but becoming a gushing leak very quickly if the tube rots all the way through...this is especially common on the vans that have rear heat.

Since problems with the coolant system can go from minor to makor very quickly and can get quite costly to repair once they become major, I would recommend having a professional look at it sooner rather than later.

Thank you very much. My husband is going to have it looked at by a mechanic to diagnose. If something minor (which we hope), he will repair it once he knows the problem. If not and its a bigger job, then we will get a few quotes and go from there. Thanks for answering in great detail! I appreciate it!
