heater problem

[Abe'sGST]

Ok, so last week when i was doing my oil change i noticed my car was leaking coolant, took a closer look and it was leaking from the radiator on the piping where the upper hose hooks up. I decided to flush my coolant this weekend and add new one, and i bought a bottle of the coolant stop leak to see if it helped out, it did but was still leaking just a little bit. I decided to get another small bottle and add a little more and it stopped the leak completely, but now that its getting colder the heater works but not like it used to. where would be the best place to check to see if its clogged up? thats what my guess is, any more suggestions to what it could be?

Any sort of Leak-Preventative products are a terrible choice. it can cause clogging, premature wear and breakdown of vital components (IE your Waterpump) or other side effects such as your heater not 'heating' as it should.

Sounds like it's time for another very thorough flush.

That stuff is the worst. You should be able to flush it out though. I would fill it with water, warm it up, drain and repeat until you get all of the bad out. Its better to pony up the bucks for a radiator if it needs it. Replacing things like the heater core suck!

The best thing to do is fix the leak,then flush the system out. After this i would back flush the heater core to get all gunk out.
