Hey folks, Ive got a leak and know veeerrrrry little about cars. Im wondering if someone can explain to me like Im five whats the step by step to determine where it's coming from and how to fix it? Im hoping it's a gasket or something easy thats just worn out and needs to be replaced, but Im pretty ignorant here (like I dont know what the names of of parts I should check... really, explain like Im five. A dumb five year old). Where to start??
