Title: Rad hose blew off
Post by: three two barrels on July 26, 2020, 09:32:49 PM
I remember reading the post a couple weeks ago about someone's hose clamp breaking and thinking that would never happen to me. Mine did not break but the top rad hose blew off after a short test drive, I had the rad recored last fall and this was the first time driving it since then, I am sure I installed the clamp correctly.

But they just look so cool....

Sorry I drive my cars... Looking cool is down the priority list...

Sorry you experienced that, makes a mess but usually it cleans up with no real damage....

Had a lower hose slip off while driving due to PO cutting it an 1-1/2 " to make it easier to install, ugh.

:iagree:
My first thought was the hose looks a little short maybe, and when the engine moves under load it      " pulls" on it somewhat? Then add in pressure.... :notsure:

I have seen this before and it's generally because the hose is wrong. If the pressure built up enough to blow the hose off then the cap is not functioning and the car is overheating.

I find a lot of people in the mopar hobby also reuse these clamps many times. Like everything spring related they have a lifespan. You wouldn't put a worn out 50 year old rear leaf back on a car.


New hose, new clamp and back on the road.

I put a little weatherstrip adhesive on the hose before installing it.  Having the hose blow off is one of my big concerns.

What hose did you use?  Did you use a reproduction with date codes or a parts store replacement?  I've heard some new hoses are a little thinner then the original ones and the factory clamps don't keep those tight.
