Hi all, I've been a member for a while, this forum has been a great resource (so much so that searching generally finds my answer without needing to post a new thread). However, my coolant leak has me perplexed and I couldn't find a similar thread.
Truck is: 95 F250 PSD, 5spd, 4x4. From what I can tell it's an early 95 model (has rad cap on radiator, not expansion tank).
I have had a really slight coolant leak for a while now, and am having trouble diagnosing it. There isn't a substantial amount of coolant under it, and it only leaks right after running the truck. It could sit for eight weeks and not leak a drop (I tried it - and the coolant level stayed the same). However, I drive it to work, and as it cools it will drip enough to notice, but not enough to measure (maybe a quart, probably less).
The previous owner (my grandpa) took a 2x4 to the Grill/AC Condenser/Radiator over a decade ago. The AC system held coolant, and so did the radiator, he never replaced it. My inclination is it's a bad radiator, but I can't ever see the coolant leaking out of it. The front is dry, the engine is dry, the back of the rad is dry. But, there is a lower cross bar (painted body color) that covers the bottom of the radiator from my view, and coolant slowly drips off it.
Before I go throwing parts at it (buy a radiator), is there anything else I should look into? Or is there a good way to test the radiator and rule it out? (I don't have a vacuum tester or adapter, but could get one if that's needed.) Any help is appreciated.
