Recently noticed the coolant in my van to be rather black, it’s not displaying any signs of head gasket failure as temperature is ok and the coolant isn’t emulsified, is there an oil cooler on the 2.2 engine that could of let go?
Yea oil cooler. Sold loads when worked at ford. They modified them for later vans. You can get repair kits on ebay etc but dont always work. Its part of oil filter houseing.
