Top cooling hose problem

[tracker1925]

My car Runs about 185 at low rmp even in high stop in go. But I noticed when I get on the highway and runing 2.3 grand of higher, she runs 210. So I popped the hood and gave her some gas and I seen my top hose collapse and letting a little of the coolent through. How do I fix this? I would really like to run my nice cold A/C.

i have seen a few of these with the 3800. usually replace the hose, or both hoses would be wise =)

Well that what i was thinking. I was just making sure it was something different.

I dont have that same issue but i have a similar one.. one day my 2000 grand prix GT 3800 overheated into the red zone in my driveway. right away i changed the thermostat and did a flush and fill just to be safe. Since then it has always run hot. driving at about 40 mph it stays about 210 -215 but when idling or slow driving it runs anywhere from 210-230. i recently changed the water pump and the coolant temp sensor and same problem occurred.. i thought maybe it had an air pocket in it but ive bled it out several times and tried to burp it but nothing has helped my problem. The gaskets arent cracked, oils clean, no leaks. top radiator hose to thermostat doesnt feel like it has a lot of pressure tho..It is 80-90 degrees outside right now... is this normal or can i do something to bring the temp down below 210? PLEASE LET ME KNOW! thanksss

I would say just look at the Hoses and see if stays round. But mine has not gone over 210 unless i had the AC on and motor wide open. If not it might be the water pump went out. My fathers water pump went out and it had some fluid moving because of the heat tranfering.

Silly question. How did your coolent look when you flushed it?
