radiator hoses and there role in engine movement
radiator hoses and there role in engine movement
(OP)
hello all, I'm new to the forums
my question is does the movement of a engine affect the rubber radiator hoses by bending or moving them?

- They can be broken.
- They can transmit vibration from the engine to the body.

The vibration transmitted through a regular, factory rubber hose was enough to break loose the entry solder joint, if the back wall solder joint failed and no longer supported the pipe. Learned this through experience..
Trailer towing is another example that can dramaticly change the dynamics of how the drive train moves in relation to the frame/body.
The additional mass of a trailer attached via the frame/body hitch changes the natural frequencies that the body tends to respond to over rough roads. Have seen a few cases where the difference resulted in engine/drive train developing a rather severe harmonic, bouncing totally out of phase with the altered (by the trailer) body movement, causing some rather dramatic excursions to the extreme allowed by the motor mounts.

A metal pipe will obviously break, or it will break what it is attached to unless the pipe and everything attached to it is as strong as the engine mount or unless a flexable section is included to cover the movement and expansion.
Even without engine movement relative to the chassis thermal expansion will cause a problem.

RE: radiator hoses and there role in engine movement
One unexpected finding was that our radiator stay rods, connecting the top of the radiator to the frame, are a major path for powertrain vibration into the frame, and thence to the driver's ear.
Few expected this, and some of the uninvolved still refuse to accept it (data notwithstanding) because there don't "appear" to be any connections between the engine and radiator - except for the radiator and intercooler hoses...
