Hi, so on my 2004 PT Cruiser I’m noticing very small amounts of coolant by the belt, which is getting into the belt and making it nice and squeaky. I’m aware I may have to replace the belt now, but I want to fix the small coolant leak before that for obvious reasons. In the picture attached I noticed this thing has a drop of what seems to be coolant on it at all times, I’ve checked for multiple days. I think it may be leaking from there. Can anyone give any advice and if it is this part what is it called, and how can I replace it? Thank you!
