    How do you blow powdered sealer into the heater core? Googled it but only came up with adding it to your coolant and letting it circulate.

    I'll check into that. I just can't understand when I did a pressure test it held at 15psi for a few hours.

    I did use bars leak last winter and it did not help.

    2003 silverado. I started smelling coolant in the cab last winter when the heat was on. No smell this summer with a/c or vent. A couple weeks ago I drove it on a cool morning and turned the heat up a little and smelled it. I assume it is the heater core. The carpet is dry and the windows don't fog up or oily. I just did a pressure test and no leaks and the pressure held at 15psi. Any ideas?

    My a/c compressor isn't working in defrost setting, my windows are staying fogged up. Compressor will kick on then right back off. I think the refrigerant is low. I was going to get a can and recharge but all I can find is the kind with the leak sealer in it. I have read not to use any with a sealer, and I have read it is OK. I am assuming that is all I can find it would be OK to use?
