Why does my car AC smell like coolant?
If your car smells like antifreeze, it could mean that the vehicle’s heater core is leaking. The heater core is responsible for circulating warm air in the car’s passenger cabin. When the heater core develops a leak, it begins circulating air with an antifreeze odor and eventually fails altogether.
Where does the coolant smell come from in a jeep?
After driving sometimes (not all!), there is a prevalent coolant smell coming from the front area of the Jeep. I notice it more toward the passenger side front; but sometimes I smell it on the driver’s side, too. I have looked around the engine bay and coolant hoses, but I can’t find any noticeable leaks.
Why does my car smell like coolant after running?
This can also happen if the coolant is overfilled. Try jacking the car up and removing the plastic cover underneath the front of the engine. Check the bottom of the water pump and thermostat to see if you find any dried coolant there. Sometimes the water pump shaft will leak slightly.
What should coolant pressure be on a jeep?
The cooling system should be under 18PSI pressure, any leak would cause you to lose coolant pretty darn quickly and you would notice the loss of coolant. There can be a rare leak that is so small it that you loss the coolant slowly (and by slowly, I mean you can notice the loss of coolant over a year).
Why does my Jeep have a bad smell when I shut it down?
One last one, if your vehicle is more than a year old, the pressure cap can be bad and a bad pressure cap will allow the cooling system to boil and let steam escape. When you first shut down the engine and water pump stops circulating coolant, the temp spikes a bit, and thus form the steam that escapes the pressure cap. I noticed the smell also.

Why does coolant smell in the trunk after running?
In the trunk by the coolant cap there is a plastic shield. Remove this and you should see a coolant air relief, or “burp” valve. Sometimes you will see dried coolant in this area which could explain the smell you are experiencing. The relief valve gaskets may need to be replaced, or the screws may just be loose, causing the leak.
Why does my car smell like antifreeze in the winter?
The liquid has to be a 50/50 mix of water and ethylene glycol. It travels from the engine to radiator through a special hose. It redistributes the heat away from the engine to save it from damage due to overheating. The antifreeze also helps the fluid in your car to stay at the right temperature during freezing winter.
