How long does a P32 radiator last?
I have a 2002 Winnebago Sightseer 27c with an 8.1 engine. I replaced the heater core a couple of years ago. As far as I know the water pump and radiator are original. It only had 40,000 miles on it...

Does your radiator overheat now when climbing hills, or idling on a hot summer's day? You can check it with a cheap IF gun from HF by taking temperature reading from the top to the bottom in a 4 in grid pattern. Cold spots would indicate a blockage. Pay attention to the area in front of the fan clutch, a radiator guy told me years ago that if they clog, they tend to clog there first. There should be a change of temperature readings from the top to the bottom of 30 or more degrees showing that your radiator is cooling correctly.
