I cam across some videos on youtube in which the topic of the cooling system was discussed and it was mentioned that the radiator cap should be replaced periodically. I don't recall what sort of schedule was mentioned.
Should a radiator cap be replaced periodically? I have had the same one on my EA82 for the last 20 years. While it is true I am a cheap bastard at heart, I am willing to buy a new one if it is recommended. Just never heard of this before. What do folks think?
