1999 Mercury Cougar: smell..radiator fluid..leaking hoses, etc

Resolved Question:

I have a 1999 Mercury Cougar. Lately after turning off the car I can smell a radiator fluid type smell. I have checked for leaking hoses, etc. and found nothing. Should I be checking for something else?

Is the smell coming out into the cab or from under the hood or from the exhaust?
Customer: replied 6 years ago.
Under the hood. Sometimes there is even what looks like steam or smoke.

Are you pretty confident it is a sweet smell just like burning coolant would exhibit?
Customer: replied 6 years ago.
Pretty sure.

Ok you need to pressurize the cooling system via a hand pump to see if it leaks down. If so you need to check many possible leak locations which can be external

  • upper and lower hoses to the engine/radiator
  • heater core hoses
  • radiator
  • intake manifold
  • timing cover
  • heads
  • water pump
