I'm noticing that after I drive my Delorean around for a bit, and then park it, roughly 15-20 minutes afterwards I can look under the car and see a small puddle of coolant on the ground. It seems to be dripping off of the frame, right beneath the passenger-side trailing arm bolt. I saw a similar post on here talking about a leak in the same area, but I'm wondering why it takes a while for the coolant to start leaking after I turn the car off?
