Unfortunately, coolant leaking from the intake manifold on the 2000 Ford Expedition is a common occurrence, especially now that the vehicle is getting up there in age. It's usually the sign of deteriorated quality in the intake manifold gaskets, which will necessitate replacement. While not the most expensive fix You may need to perform, it can be time consuming to deconstruct and put back together. On the other hand, it's possible that one of the small pass-through coolant lines has sprung a leak. In any case, stay vigilant that Your radiator reservoir stays clear of oil, and Your oil dipstick stays clear of coolant. You should get it checked out as soon as possible, but as long as You're not mixing fluids, it's not severely critical.

A 2000 ford expedition intake manifold coolant leak could be a result of a crack on the manifold body.

Some intake manifold gaskets also seal engine coolant, and if the gasket wears out it may lead to a coolant leak. This may produce a distinct coolant smell, along with steam, and drips or puddles of coolant underneath the vehicle.
