Ok so I'm fairly new to all of this. I own a 2003 Lancer es that I have taken to the shop several times already due to overheating the cooling system was basically replaced. The car was working perfectly and then just gave out on me, white smoke came from underneath the hood. I soon realized the passenger seat floor was wet most likely from coolant. The a/c doesn't work either. Anyone have a clue to wear the leak might be/ to how much it might cost? Thanks for your time and help. p.s. sorry if i wrote this in the wrong thread.

 

have you tried doing a flush? completely remove all coolant from your rad and the reservoir. disconnect 1 hose and just flush it with water (just put a hose down it and turn it on.) and then after connect it back up, and then keep putting water in it and see if you can spot a leak.


if that doesn't work...


purchase K-Seal 8 and dump a bottle in and It repairs leaks and cracks in radiator, head gasket, heater core, freeze plugs, water pump casing, cylinder heads and engine blocks.

 

Sounds like the heater core.

 

sounds like the heater core to me as well.....

what part of the A/C isn't working? wont blow? wont get cold? what?

as far as the stop leak, don't put that GARBAGE in your vehicle...... fit it right.

If it overheated and was run out of water and stalled out on you, you are going to need to have the engine checked for damage, there is a very high probability you will need an engine replacement
