Purchased this van used. The heater core was bypassed I got hoses and hooked it back up hoping to find the problem. When the van is started water is pouring out from in the very middle like underneath the radio and heat/cool control panel. Please help I do not know what this could be.

Good morning.

If it is coolant, it is leaking from a failed heater core. It is the only component inside the car that carries coolant. It must be replaced to resolve the issue.

Are you going to attempt it yourself?

I tried to upload a picture of where the water is pouring out from. It would be a real big help if I could find a free manual on this van.

Okay, I will get some directions for you for this.

I do not know about any free manuals but parts stores have manuals for this.
