How does one tell if it is time to replace the radiator hoses?
If they never have been changed you are past due. Overly soft hoses, leaking hoses or hoses that balloon up when the engine is hot are in need of replacement.
06 has the new compound hoses so you should get a good 8 to10 years out of them providing that you kept the ph balanced in the cooling system. So they were due in 2016. Another way too tell is squeezing the hoses if they fell squishy or they crunch then repalce them quickly or you could be one of those people sitting along the road with steam rolling out from under the hood and fried engine.
Thank you for your input. No bulging observed but since they are well passed the suggested 8-10 year age, I have ordered new hoses as well as a new thermostat.
