The heater core of my 04 2500 dodge ram 5.9l cummins is leaking out the catch pan tube in the firewall. I'm capable of pulling the dash and replacing the heater core, but I don't have time to do it. A very mechanical guy I know recommends radiator stop leak to seal it up, but I've heard horror stories about it clogging up engines and having overheat issues. Part of me doesnt want to touch the stuff and part of me thinks those horror stories are from people who thought "more is better" and probably dumped a whole bottle into the cooling system and plugged it up. It's not leaking really bad. Just leaving a small puddle under the truck. Anybody have anything good or bad to say about this stuff?
Thanks
