I know. I replaced the throttle body heater when I did the radiator. I should have replaced the lines at the same time.

 

Once you claw off one piece of dry rotted hose and replace it with new, the system pressure holds just a little higher so the next rotten swelled-like-a-sausage hose will step up. This is the MayPop method, as in May Pop any minute.

 

I believe AB has hose sets on sale this month, might as well get it over with all at once.
