Recently, the vehicle has started having a pretty significant coolant smell around the engine bay when I get out of it after driving for a while.
  • I can also smell it when idling then pulling forward (like in McDonalds drive-thru).
  • I was idling in my parking garage for 30 mins on a conference call the other day, and when I got out the smell was VERY strong.

So, I took it to the dealer. They said the coolant level was LOW, but they couldn't find an actual leak and gave me the vehicle back...

Anyone have a similar coolant smell? If so, what was the cause?

Thanks. Note: 2 issues today; posting them both.

I've replaced 3 or 4 radiator caps on my 2014 Chrysler 300 SRT in 55K miles, the tank is always down a little so I top it off couple times, then replace cap. My son thought it was the water pump weeping but never saw any evidence, but coolant temperature so high it evaporates. Think the cap is a 21 psi. Thought about using higher rated cap but decided not too. Haven't had any problems with Trackhawk but only have 22K. Could be coolant bottle but cheaper to replace cap.

Definitely a common known problem is the factory radiator cap. Have a look around your engine bay as evaporated coolant usually leaves a white salt like residue behind as evidence.

^^Apparently this is a common issue that the water pump could be potentially failing. There are no visuals or sounds that are attributed to the leak and smell, so once the pump has gone, it has gone! Listen out for a metallic /clicking sound of the water pump and this may be evidence that it is failing. There is a video on youtube of this problem done by an independent review (owner driver)

Good info to know abt TH BUT it may be another problem. I had a hemi in my preTH Jeep. It lost coolant and it was a mystery. Dealer said didnt know and on and on, but an oldtimer showed me the problem. The engine intake manifold gasket cracks or whatever and allows the coolant to be sucked into the intake and burned off. Nothing shows but the coolant is missing. the intake leak is often found by spraying carb cleaner around edges and engine speed picks up. It cost me a G to fix the engine. New gasket and no more mystery.
Maybe thats your problem, maybe not. Hope you have a warranty because when loose too much coolant then you could loose engine. Good Luck. KennyG

How many miles on the car? water pump usually fails between 40k-50k, this was in SRTs, I don't know if Trackhawks are the same. Strong smell is most likely from water pump failure coming soon.
