Coolant leak

[78F350]

The way I see it is two types of fluid can come out that drain from the HVAC; water from condensation with the AC running or coolant from the heater core leaking.

If it is not leaking from the HVAC drain, in the front of the car, there are three types of coolant lines.

• Big -main coolant to and from the radiators.
• Medium -heater hoses.
• Small -radiator bleed lines attached to the top corner of each radiator.

That's all else there is.

Many of those lines are exposed now. Before I tear into it I'm going to put some more water in it and run a more extended test. If there's a leak source besides the HVAC drain, I'll find it. I hope.
