93 Ranger leaking coolant!?
I have a 93 Ranger in which I recently put new hoses, thermostat, and coolant in. My truck also has the bypass kit installed in the lower hose. Now in about one weeks time all the coolant in the overflow bottle leaks out. I looked underneath and it is not coming from the hoses. I can see it dripping from what looks like two plastic drains, one on each side of the radiator. One is located right below the drain **** and the other is in the same place just opposite side of the radiator. What are these for? It never used to leak at all before i changed the coolant and I didn't even touch these two drains. Any thoughts would be appreciated. Thanks Bob

i would go over the two plugs and see if they can be tightened just a hair..all i can think of is the coolant has some heat to it and expanded the plugs and thats all i can think of..other than that just go over the whole area where you worked on and snug up clamps ..sorry i cant help you much but its a start

The drains i was talking about don't seem to have any caps on them. They just look like hollow tubes hanging out the bottom the radiator. They come through the frame and have a rubber bushing around them where they go through the frame. I know i am not describing it very well but I don't know how else to. Thanks again Bob

Bob i dont realy know about it much myself ..do you have a repair manual and maybe it will shed some light on the source..i looked on my 92 ranger and i dont know exactly where it may be coming from your truck as i dont have the same problem as you...im wondering if you can take your truck to a garage and have your rad pressure tested...let me know how you made out and where the problem was at

The two "drains" you describe are actually a mounting surface. They are not drains. There is a drain **** in the lower part of one plastic end tank that is used to change coolant. If both sides look to be leaking, I suspect the rubber seals between the aluminum radiator core and the plastic end tanks is worn out. I would replace the radiator if it gets much worse. Some shops claim to be able to recrimp the tank tanks and install new seals, but I have never had much faith in repaired aluminum/plastic radiators.

Pat is right. Those are simply the two lower mounting pins, and no matter where you have a leak, this is most likely where you'll see the results (drip, drip). I know, I've changed my 94's radiator twice. And yes, the leaks usually come from either the seams or the hoses.
Since this started soon after replacing the hoses and such, the first place I'd check is where the hoses mount. Did you use new clamps? Although the spring-clamps work fine, they're a pain to deal with -- get a couple of the worm-gear jobs.
Good luck.
