I have a 1993 Accord 10th Anniversary Edition.

For some strange reason, after i turn my car off, I heard this bubbling noise. I dont know what it is. I replaced my radiator a few years ago, so i know its not that. My thermostat doesnt read hot, so im pretty sure its not that.

Can you help me out?

 

Check your coolant level and then pop the hood after you turn off the car and there is a hose that goes from the radiator to an overflow bottle VERY CAREFULLY look at that and I bet the noise is coming from there. Let the car cool down, top off the radiator, maybe put a little bit in the overflow bottle (as long as it's below the max fill line). If the problem persists and the car is not overheating you may have a bad radiator cap

 

My brother had that happen to him one time. If you aren't running enough anti-freeze, or just pure water, it could be boiling off.

 

This is way out there, but my car makes a bubbling noise when I turn it off after the A/C has been running... the noise comes from the passenger footwell.

 

Finch, yours is the AC refrigerant continuing to flow through the evaporator. That happens until the high & low side pressures are equalized.So if kingsham is hearing this sound, it's normal.
