I am still having cooling concerns. A radiator guy said with the car warm, and the cap off, the fluid should just sit in the car and not "gush out." He said if there was undue pressure, it could be a head gasket!

this is the new/used motor I just spent the last 3 months cleaning, painting, and transplanting into my GT.

If the press. gets too much the caps will blow?

the temp guage seems to go up, then down and back. the fan did not want to come on at first, so the guage went to 240 or higher, the light came on- engine seemed ok- not too hot.

Can you all help again? Is it bubbles still?

You need to have someone run a "block test" on it. Many shops will do it for free and it will positively tell you is there are combustion gas in the coolant.

The thermostat jumping is likely due to it having air in the cooling system. Pull out the thermostat as you are filling it. Leave it out a few days till you are sure the air is purged.

Even if there is preasure coming into the cooling system it will not blow anything up. The cap will open at 15 PSI and push coolant into the overflow bottle.

Is there a good way to check for a blockage in the cooling system?

If the tubes are blocked you will be able to see the crushed spot. You generally can feel the radiator and find it, but even then the flow will continue through it. It is a little harder to know about the engine. Generally is there is no engine flow it is from waterpump impellor issues.
