So I am driving today and I notice the low coolant light comes on with a funny smell. I pop the hood and the coolant went somewhere. I remove the carpet and the side panel and the heater core is leaking. The heater core was spraying coolant. I have talked to a few people where this has happened, but why would it spray? I can tell the heater core was bad, I have read about this... http://www.sancarlosradiator.com/VoltageDrop/index.html ... trying to see if any1 else has any other info before I replace the heater core.

Amazing how much pressure builds up when the engine gets warm. The heater core is quite easy to replace, just do a search. Someone found a replacement for less than $50. New O rings are required.

Do yourself a favor, cover the area under the heater to catch the antifreeze. It evaporates very slowly and will remain in the foam pad under the carpet for a looooong time. Plus, it is quite sticky and hard to clean up.

A newspaper will absorb a lot. Just use the black/white sections so that the color ink will not bleed on the carpet.

Yeah I've done one before. I took it out in 40 minutes, I have just never seen one leak as quickly as this one did. The other one I did had a slight leak when it started to go.

It won't let me edit the original post. The heater core was leaking when the car was off, but while I was driving it sounded like it was spraying a little on to the carpet.
