Default Oil cooler lines question

I'm looking to run oil cooler lines across the top of the alternator (80A). There is a small gap between the lines and the alternator. Any idea how much heat comes off the alternator?
I don't want to boil the oil in the lines but I have limited space to snake the lines through. The image below shows a test fitting using plastic lines about the same diameter as the (expensive) Aramid oil lines. Thoughts?
Thanks!
Joe

Iíve used this in the past with brake line.

To answer your question the alternator canít get hot enough to get any hotter than the engine is already doing but if youíre trying to maximize the potential of the oil cooler you would also want to protect those lines from any additional heat.

Hey, thanks. That does look like a good idea.

Not that much heat to affect the lines. Youíll be ok. I have mines routed the same.

That kind of hose and hose clamps makes me a little nervous for an oil cooler line?

Yup, just mock up lines. Those are plastic food grade lines very close in size to actual oil lines.
