Quick question (water pump)

[cgator]

im having a little problem with my 97 gtp it seems i have no coolant going to either one of my hoses neither upper or lower and when i hit the throttle the lower hose collapse's .... i changed thermostat and flushed radiator and i know radiator is not clogged cause during flush water came out both ends .... now when i drive the car stays at about 180* but as soon as i stop it climbs up to about 240* almost in the red zone ... could this be a bad waterpump ?

thank you ahead of time for your answers

Wait. You know the hose collapses but you havent changed it? It is my understanding that the radiator hoses are reinforced in such a manner so that they wont collapse.

I would also add, that just because water comes out both ends of the radiator is no indication of whether or not there is any blockage in the radiator. Mine was blocked and it still would flow out both hose points, but it was blocked in the lower end drivers side with more crud than Ive ever seen in a radiator.

The only way I know of that you can truly tell if there is a blockage is to get the car up to temperature is to feel along the tanks for any differences in warmth or you can get a non-contact infrared thermometer and take temp readings along the length of the tanks and see if there are any major differences in temperature.

Another issue that would sorta explain your temperature jumps when you stop is that the fans may not be working. There is always the possibility that its the pump but Ive never known one to work at speed and stop when you come to stop light or something like that.
