My heater core is clogged and I live in pa so it's too cold to back flush it, what do you guys think of running peak flush stuff until it gets warmer to drain and flush it, or any cheaper options because I'm blowing cold air, and slightly overheating

Start with a normal flush with a garden hose.

Do the heater core, engine block and the radiator all separate.

Refill the system with 50/50 mix or normal antifreeze.

Peak Flush? never head of it and I have been working in the automotive world for a long time.

We sell it at autozone peak the antifreeze brand makes a flush, its too cold now to use the good ol hose

eh won't hurt anything, flush it out, then pull it into a warmed up building. as long as the water is moving it won't freeze, unless you are in Alaska.
