I have an old 97’ Expedition that has a leaking heater core. It needs to be repaired but the cost it more than the value of this old vehicle. It has 274, 000 miles on it. Mist is coming from the vents now and i saw coolant dripping down on the floor mat on the passenger side. I was told to try a Bars Leak but i’m not too sure if that s a good idea. I heard that stuff get into every crevice and eventually the car can overheat down the road or ruin your head gaskets. Any thoughts on this?

Do you need Heat/defrost where you are?
you can bypass the heater core by hooking heater hoses together in the engine conpartment. But you will have no heat.

There are heater core bypass kits at auto parts store/amazon

No, I currently live in Henderson Nevada and commute between there and Phx. So if there is a leak somewhere how can i stop it from leaking without having to change out the heater core?

Thanks

There are 2 hoses that attach to the heater core from in the engine compartment. The coolant runs in the heater core thru one and out thru the other.
You can take the 2 hoses off the heater core and hook them together. No more leak.

If you can not understand that, i strongly suggest you have a friend/family bypass heater core or hire a mechanic to.
