1997 Heater Core disconnected - how to test?
New here - and new to working on cars. My son wanted a truck to take down to school later this fall, and so we bought a used and somewhat beat up 1997 Ford Ranger Extended Cab with the 2.3L 4 Cylinder engine.
I did my normal shakedown during the test drive, but I missed something kinda big. When the previous owner mentioned that the heater didn't work, I figured that the blend door or blend door actuator was probably the culprit based on my old '96 which met an unfortunate end at the bumper of a cement truck...Knowing that it could be rigged up to work by going in through the glove box etc. I was ok with just using it as a bargaining chip to get a lower price.
But upon further inspection I see that the heater core has been bypassed completely and so now I suspect that the heater core may have been leaking at some point. I didn't find any water damage on the floor or anything, though, so who knows?
So, is there a good way to test the heater core for leaks so I know if it needs to be changed? I'd hate to tear out the dash and find out that the core is fine.
On the plus side student is heading to San Diego, so having no heat isn't the end of the world - the project may wait for next summer.
Thanks in advance...
