Thanks for all your help, I borrowed a rad pressure tester tried it and it held good. Then I got an idea, fill the rad as much as I can then hook up pressure tester and pump it up. I did this a few times adding more water each time and opening thermostat housing to let air out until one time water came out. Then I started it with the fan on bipass running steady until I seen water starting to circulate and steaming. Plugged fan back in ran it for quite awhile letting fan kick on 3-4 times and it's perfect. Wish I knew this before buying a new sensor and taking the front end apart to get rad out. I noticed the rad cap doesn't really lock on like a car,it kind of just sits there but doesn't leak.
Is it ok to remove thermostat and run it without one for better circulation.
