These hoses are always overlooked! Dont neglect changing them when you change your radiator hoses! Oh and another important hose is the bypass hose. All these lines carry coolant and a small little burst in the hose can create a huge huge headache and if you're not aware and keep driving with low coolant, you can destroy your engine.
The heater hoses are very inexpensive and often times, you can buy them by the foot instead of buying specially molded ones from the dealership. In the past 2 months, my friends car broke down twice due to a bursted bypass hose and heater hose. I replaced those yesterday and also the lower radiator hose and another heater hose as preventative maintenance(replaced upper radiator hose 2 years back when it bursted on the freeway)
