Coolant Hose Replacement

OK, I bought the Roe silicone hoses (2). Changed out the crappy clamps that led to leaks around the water control valve. But there are many other rubber hoses on the car carrying coolant. Which ones do you guys replace, and how often?

I did the same thing when my hoses burst in my 97 about a year ago, was not even driving the car hard...

I love the burp valve on the Roe hoses..

I have never had any other problems,(30k miles) the other hoses seem great...

Thanks Blue. Damn good dog. Girlie is not too bad as well. I've got a Border Collie. Re-wired the house last weekend.

Frankly, I am still watching our heater hoses CAREFULLY...noting NO signs of problems yet. I posted a little something on this in Dec. 2005:

"Heater hoses not a bad idea either...though, I have seen less problems with them (except on later Gen II's with the clamps that tend to slide off of the water valve)...noting that with equal pressures in the system, one might expect the heater hoses to be less inclined to rupture with their smaller diameter giving a lower wall tension via the Laplace Law concept(at least, as my poor old mind tries to recall the facts). "

And, Ron followed with the proper diagram and formula:

I love Google:

LaPlace's Law
The larger the vessel radius, the larger the wall tension required to withstand a given internal fluid pressure.

For a given vessel radius and internal pressure, a spherical vessel will have half the wall tension of a cylindrical vessel.
