So on my v10 that runs great never over heats , the lower rad hose pops off { when it wants to } first time was on a hot day with the air on , i put it back on filled up and left . happen again a few days later at my house , i put it back on with 2 clamps . has been about a month or more. left it idle and it popped off last night . its only the lower hose to the rad. the temp always runs on the low side . i was thinking of gluing the hose or putting some screws in the tube so the hose cant slip past with the clamp on . never had this happen on any car or truck before.

 

That seems kinda strange....... What kind of clamps are you using? Might want to replace your radiator cap... it may not be releasing pressure...... also may want to test the cooling system, see if it is building pressure as soon as you start the engine..... (head gasket trouble?)

 

...and don't use screws.....there would be little possibility of properly sealing them.

+1 on the cap. Seems pressure related...

 

i worry about the head gaskets { i dont want to do that job LOL} this time i left the cap loose its not over flowing runs cool . i have normal clamps on it now . just strange its the same hose every time and not all the time and i drive it a lot . i know i dont like wasting antifreeze lol

 

Screw clamps or spring clamps? (normal is as normal does........ )

Wonder if there is something on the hose, or the part it clamps to, that is lubricating it nicely....

 

screw clamps { 2 of them }

 

STOP USING SCREW CLAMPS ON NEWER STYLE RADIATORS!!!

The newer radiators plastic radiators cannot handle the torque (or over-torquing) people apply when using them in place of the proper band style clamps. It's worse when Americans refer to the band clamps as being inferior and slap on a so-called "better" screw clamps. Said person then tightens the clamps with as much oomph as he can muster, believing the hose is properly secured. Instead, he has most likely succeeded in breaking the neck which will lead to problems with the hoses falling off and/or loss of coolent.

 

Screw clamps, when used PROPERLY, provide just as good a seal as the spring clamps. OEM uses the spring clamps because they are cheaper to manufacture, and quicker to install.... both propositions save them money..... There are also a wide variety of screw clamps...... some better than others.

 

Perhaps, but the band clamps, which originated in Europe, apply the correct amount of pressure without damaging the plastic neck or lower outlet. Screw style clamps are for Luddites who refuse to accept that technology changes and improves. The band clamps are superior in many ways, but like I said, the screw style allow the installer to apply too much torque and damage the radiator.

 

Properly installed screw clamps are certinaly good...as good as the installation, if you can find some other than the chinacrap screw clamps that so many places carry. The good ones are few and far between, and I suspect that most people overtighten them.

I use the spring type on most of my vehicles. Even bought one of the fancy tools for them!

But on this problem, I would change radiator cap. They are pretty inexpensive. Something is either creating too much pressure, or not allowing for the proper pressure relief.
