Problem with coolant system?
I think I might have a problem with my coolent system. When the car is heating up before the thermostat kicks open the radiator builds up so much presure it collapses the top radiator hose. If there is a kink it the over flow hose could this cause this. My overflow tank'* level doesn't change at all. So I think there is a kink in the line or it is clogged.

Try a new 180 thermo or just inspec the current thermo for crap preventing it to open...my wagoneer used to do this, i changed the Stat and the top rad hose...problem solved there...but that was a way less technical vehical...

This does it when it warms up. When it gets to ~180 it opens up and radiator hose fills back up. Like I said before I think the over flow hose is clogged or has a kink in it. When the radiator hose was colapsed I pulled the radiator cap off and the radiator was pretty low but the overflow take was full still. If the radiator is low shouldn't it pull fluid from the overflow tank and vice a versa.

I is brand new but it is a 16lb and the stock was a 15lb. Would that make a difference. I looked around and couldn't find any 15lb, only 16lb or 13lb. What would be making the top radiator hose colapse like it is. It has to be pulling some good vacumn it seems, them hoses are pretty thick.

I am going to go buy a new radiator cap, upper radiator hose and overflow hose. Just to solve the problem. At this point I think they all come in to play. I checked the over flow hose and there is a kink in it just as it goes in to the overflow tank. The upper radiator hose is getting pretty weak it fells like. It runs half colapsed almost all the time and I can squeaze it and it isn't very strong anymore. As for the radiator cap I am not sure what is up with it. It is one of them with the pressure release valves on top of it and my car can be running at 200F and I can pull the pressure release valve an nothing will happen.
