This may be a dumb question but today I cranked up my John Deere 4040 and let it run for about 15 min. While it was running I noticed some coolant starting to drip out of the radiator cap. It was not gushing just some steady drips. I let it cool down for a min and let the pressure die down and unscrewed it and put it back on. I noticed the level looked normal and I made sure the cap was correctly back on. I cranked it back up and let it run for about 10 more minutes and no issues. I looked at the coolant level again and it was at the same level. It was very humid today where I’m at. I’m also not certain if the cap was just not correctly on the first time. Never had this issue before and was just trying to see if this was anything to worry about. I didn’t know if the humidity can cause there to be extra pressure in the tank and cause it to boil over. Like I said after taking the cap off and putting it back on I did not have any issues.
