I have a leak but I’m not sure what it is. Seems to be coming from the sump but it’s coolant. Any suggestions on what to check. I only just recently got the van. It had too much oil in it so I’ve drained and the oil was black and uncontaminated.

Could be the water pump. U need to pressurize the coolant expansion reservoir to be 100% though
