Alert: Lower Rad Hose clamps

Just thought I would post a bit of an alert so others can avoid the problems I have had. This is the second time I have had a lower rad hose clamp deteriorate and come apart resulting in coolant loss...everywhere.
I should have taken some pictures but it is an easy check for anyone.

The gear clamps are located underneath the rad on each side of the coach. They attach (on each side) a rubber hose from the rad that bends to attach to the power steering cooler. These are not quite a standard gear clamp but replacement with a standard Tridon will be fine.
I am not sure as to whether these were originally stainless or not but if they were they weren't of great quality as two rotted off, resulting in the coolant loss, and the other two were close. They were so badly corroded that I couldn't use a screwdriver or a 7mm socket to get them off. A pair of pliers was used and broke them apart fairly easy.
If you find that you have some that look in sketchy condition replace right away!
To avoid excess coolant loss I would position the new clamp as close to the original as possible, loosen the original and remove and then slide down the new one in it's place and tighten. Top up the coolant afterwards if you have any loss.
The first time one broke on me I was stopped and thankfully 100ft away from my shop. Drove it in and replaced the clamp before the rad could empty. Yesterday I was at home unhooking the car from it after a short ride from my shop to home when I smelled antifreeze and then it started puking out all over the road. Thankfully I got it backed into my driveway and again installed a new clamp before it all leaked out. This time I replaced the remaining two as well.
If this would have happened travelling the results could be much different and expensive and a huge inconvenience.

Hopefully this prevents someone else from having an issue.

All the Best,

James

Curious to know the condition of all of you that checked. My Berk is an '08 and has made 1 trip to Alaska (although oil sprayed prior to going) but it didn't do any of the undercarriage any favours seeing a brief period of salt on the roads.

I just checked mine. They look ok one has the start of what looks like some corrosion so I'll be replacing at least that one. Thanks for the heads up!
