I have a 1998 American Eagle has about 60 k miles on it. it over heats when climbing a sustained grade. I know it is heating because when it got hot it was boiling over. as soon as i get off the grade it cools down to normal operating temp of 190 and it does it pretty quick. I have a new radiator not more than 9 months old. it has a side radiator i can see the fan working. just can't figure it out. yes it has the proper fuilds that i top off before every trip If you have any ideas please let me know thanks

How was it before you installed the new radiator? Is this a new problem or an ongoing condition that the new radiator did not correct?

it worked fine it is the exact same radiator that came out of it. the one thing i havent done is replace the cap could it be that minor of an issue?

Air trapped in your cooling system perhaps?

i thought about that but i just got done running it 600 miles you would have thought the air would have disapated in the system running it that long
