No heat after discovering stop leak in cooling system
I discovered stop leak in my cooling system after my head gasket blew about 2 months ago. Had my thermostat, hoses, radiator, water pump, and timing belt replaced all at once. However, my heat still does not come on. Looked at the switch under the hood and confirmed that it works... so now I'm not sure what it could be. I don't think it'd be the motor, but is there something from the stop leak that could be causing no heat production?

Maybe it clogged up your heater core. Unplug the hoses that go to the core and flush it out with a hose. If it's blocked, it will give you some resistance. If not, at least you've flushed it out.

So you replaced everything heat/cooling related except for https://acurazine.com/forums/third-g...ve-diy-747304/ ? If it had stop leak it would most likely be in every part along the way to & from the radiator. Which could have a clog anywhere along that path. If that wasn’t replaced I’d check and or replace it to, pretty cheap compared to everything else you had done or replaced. And for me at least, I’m not trusting enuff to not change it & hope there ok. Also did you have the heater core checked or flushed out? This is all assuming the fan blower and everything else is working still as normal. Does your AC work still? And have you checked to make sure your coolant is actually circulating through your engine and back?
