I think I need to flush my radiator. I’ve got plenty of fluid in the overflow resevoir, but my engine temp continues to rise. I think I have sludge build up. But, the cap to the actual radiator is sealed with strong warning labels saying never open. So how can I flush the radiator if the actual radiator cap tells me never to open it? ---

I think it means DO NOT OPEN WHEN HOT. Why do you think you have sludge if you haven’t looked in the rad? Perhaps your over-heating problem is a faulty thermostat. ---

You may have ORS. Old Radiator Symptoms. If the radiator has never been changed, it’s time. The little fins are probably corroded away. Pull the shroud back and look. If 5% of them are gone, it’s 100% time to change it. They never want you to check the fluid level by opening the cap; they want you to look in the reservoir. You can still remove the cap. You probably don’t have enough training to work on your own car. I don’t recommend that you even do a flush by yourself.
