I went to flush my heater core out as it was blowing cold air late last winter,,,it only did this because I added some bardaul to try to stop the anti freeze from leaking into engine oil
After several weeks I was finally able to find the one and only wrecker engine in Yellowknife,, finally installed and works like a charm but I need to flush the heater core to get the crap out of it, if it does not work I have to take the whole dash apart, seriously
But gm conveniently has one hose that has a squeeze clamp BUT the other has a push on fitting that needs a special tool to take it off ...really
CAN I just cut both heater hoses and do a reverse flush to get the stuff out and then resplice the hose..back in the day both hoses could be taken off , but t he engineer sos tried to find a way from us performing that simple task
thx in advance
