we have noticed a strong pungent odor from the warm engine compartment?

Hello,

Strong odor can come from leaky radiator, it can also have a smell if the engine is overheating.

Do you smell anything from the passenger compartment? If you do that could mean a coolant leak in the heater core.

Are you experiencing any issues?
Does it overheat?
