Both of my Hondas (96 Accord 01 CR-V) leak coolant when only the defrost is running. My radiator is fiull and the overfill tank is between max and min. I noticed it a few days ago with all teh snow. But when the heater is on there is no coolant leak. No coolant leak with both defrost/heater on. I run the defrost on both Hondas without the A/C on. Any ideas?

Any ideas? Anyone?

 

Probably have a leak in one of the lines that goes to your heater or a leak in your heater inside the car. If it smells like coolant inside your car then your leak is probably inside your car.

If not then check the outside. Try following the hoses and see if one of the connections has green crud around it. If so then there is your leak. If not then keep looking.

 

I checked around last night. I let the defrost run for like 10 minutes and it didnt leeak anywhere. I looked underneath and nothing. Maybe it was a one time thing.
