Well, took the thermostat out and replaced it with a new 160 degree one. Drill edthree holes in it and reinstalled it after testing it on the stove. Refilling it was a breeze with the holes in the stat. Practically filled the hole system. Started it up and ran it for 11 minutes before blowing the lower rad hose off the tubing. I have two hoses connected together to cover the distance. Took the pipe to the muffler shop and had the ends flared out. Re installed it, refilled it and started it up. Temp stayed around 190 for about 18 minutes before the upper rad hose blew off this time. Yes i did it again. Took the pipe down to the muffler shop and did the upper one. Dont know why i thought the upper one would be ok. Put it all back together again and started it up. Didn't run it long this time because sdomething hit me.
I have a rad cap on the expansion tank that has 13 lbs release. I also have a rad cap on the rad that is also 13lbs . The vent tubing from the rad is connected to the rad tubing coming out of the expansion tank. So i dont have some sort of bottle for the cooling system to vent too.
Am i on the right track. Do you all have vent bottles in your systems?
