Larry sorry to hear about your troubles.
Would anyone on here like to guess at what milage to change the radiator to a new one. I had a Mazda that the radiator went out at around 125,000 miles. The radiator came apart at the plastic/metal interface. I absolutely do not want this to happen on my E320 and plan on going ahead and replacing the radiator at around 120,000, along with the hoses and water pump. I am even considering going with an oversize radiator from Renntech. Any thoughts on this ya'll.
