When I have the engine Idling and I snap the throttle the upper radiator hose colapses then returns to shape...what does this mean? is it a problem? I just burped the system and it's still doing it.

Does this cause any kind of cooling issues? today it was 90* around here and the car runs fine until I hit a hill and then the temp climbs instantly to the M-A in "NORMAL" and will creep past it if I dont blast the heater, all the cooling systen is new except the fan and both speeds kick on, with the dyno tune te fans were set to start up earlier and when the temp outside temp is around 70* it doesent matter how I drive my car the temp stays at the O-R, What is causing this? it's my DD and I need it to stay cool ALL the time.

Is your thermostat partially stuck closed?

I would have your coolant system pressure tested. Look at your upper hose, it might need to be replaced. I have seen them come apart and flap on the inside blocking passage.

Apparently my ex-husband made that mistake.

It most likely means your hose has started to get soft. Best to change it, they aren't that expensive.

Also, there can be issues with some silicone hoses if you happen to run those.
