ok brothers i hope anyone who reads this can help me, before i left today i wanted to check the lower radiator hose to make sure that it was on very tight. i seen that it was bound to pop right off like it was coming off the radiator. Then i losen the clamp to re adjust the hose to the proper spot and tighten it very well till the hose went thru the clamp then i stopped because i didnt want to over tighten it to cause a leak. I started up the car,then checked the lower radiator it didnt move or slide etc.

And if you guys are wondering/thinking i have done the following.

1.all the air is out of the both bleeder screws.
2.radiator cap is new
3.the lower radiator hose is new. with a new clamp
4.t stat is new and the correct LT1 one
5.the cars temp is perfect the fans are coming on properly and the temp goes back to the middle after fans turn on.
6.I dont hear any garling or boiling after i drive the the car.

hey im sorry guys the problem i am having is that i tighten the clamp really good on the lower radiator hose,after 3 weeks i check the hose and its coming/sliding off the stem of the radiator. thank u guys at least for the replys

Does the stem still have its nub? Is the hose on far enuff and the clamp far enuff down the hose?

notice how the clamp is just below the nub.

Does the hose fit properly? Eventually they can become swollen and not fit snugly- and in combination if the 'nub' is missing off the end of the stem its not going to stay.

The hose should stay on the stem and seal without having to be clamped. Obviously you wouldn't run it this way- but its one way I check to ensure the hoses aren't worn out.

They are cheap to buy new if it is bad. Check both the hose and the nub- I suspect one or both of those will be your problem. If not the system might be building excessive pressure- How old is your radiator cap?

1.hey thank you guys,I did what you said chevydude97,the hose wasnt all the way inserted in the radiator,and then i put the clamp just a lil bit below the nub and tighten it all the way good.

2.And to procharged94LT1 the radiator cap is new and the hose is new too,thank u for informing me on that.on the radiator cap it is an 18 psi with a red lever on top.
