I've had water leaking from my 90/91 for ranger for the past month to such an extent that I have to refill the radiator every two days. I climbed under the truck and snapped this pic of where the water appears to be coming from. There is a hole here which looks like it's supposed to be here but doesn't look like a bolt would go there. I'm not a mechanic so I just don't know. What is this hole and why is water leaking from it?
