Ok, Guys I fixed the Heat problem. I was a ble to flush the core and
engine. After flushing everything until the water was clear bolted
everything back and was tested. It all worked fine after the the
flush. I has really good heat and the temp dropped from around 210 to
195 on the dial.

So far soo good!!!

Next week shocks!!!

Thanks for all your help guys!!!
