The heater core in my truck is leaking real bad, causing the windows to fog up when I run the heater. I know it is easy to install a new one, but is it possible to by-pass the core with a hose(sold at an auto store) just until I have the money to replace the heater core?
Thank you very much!

Re: Leaking heater core
Yup, I've done the same thing before. You have to just find a tube of some sort that is small enough to fit inside the hose's going to and from the heater core. Remove both hoses from the heater core, insert the tube into the hoses and put some clamps on both sides nice and tight! Good luck

Probably still have the old antifreeze in the heater case, may have puddled in some low area. I don't know if you'd have any luck swabbing a rag in there anywhere, or how to dry out the inside. May have to let it dry over time. If new core is not leaking, nothing wrong with it. Keep checking for leaks and monitor your coolant level. If it is old coolant in the case from first core, get creative and figure a way to dry it-shoot compressed air back through the vents?
It will be the heater core. If you can smell it inside the car and it's steaming up the windows the core will need to be replaced. Remove the heater core housing and check to make sure its leaking from the core itself. You might get lucky and have a leak from the hoses running to core instead. Hope that helped.
either your heater core has a leak or one of the supply hoses has a leak which is running into the car where the hose clamps to the heater core inlet or outlet tube. hopefully its just a clamp tighten fix.
The only part that has coolant running through it under the dash, is the heater core, when it goes bad, you will smell coolant and the window will fog up, leaking heater core, replace it be for it start's to over heat your engine and cause more problem's in the long run.
Sounds to me like the heater core is leaking again. If you're smelling antifreeze and the window fogs up then you're getting coolant into the heating system. Most likely cause is leaking hose to heater core or the heater core it's self.
1st make sure it's the heater core. Usually it's the passenger side that is wet. To confirm it's the heater core, 1. do you smell antifreeze? It has a sweet smell, and should be easy to notice it if leaking. 2. Do have a problem with the windows fogging up, and turning on the defroster doesn't help or makes it worse? If the core is leaking, the moisture from the leak will fog up the windows, and the defrost mode struggles to clear the glass, as moisture is blown up the vents onto the glass. If 1 and 2 don't exist, the water on the drivers side is most likely a leak from rain along the door gasket, or windshield, or firewall.
