I have a tiny coolant leak in the upper engine area.

Two year ago I replaced the water pump, the radiator, the upper hose, and the lower hose.

I did not replace the heater hoses. So a few weeks ago I replaced the upper heater hose/intake hose. I thought that would fix the leak.

Nope.

So I am going to replace the lower hose and see if that fixes it?

It's just a pin hole size amount of coolant that sometimes shoots up onto the hood and then hits the fan and splatter around.

What else could it be.
