I'm new to this site and to my Ford Ranger, and I wanted to know if you guys could assist me with my issue? I recently took my ranger to a Jiffy Lube to get an oil change and the attendant informed me that my antifreeze was brownish color and need to be changed, however they wanted $80.00 to do the service. Of course, I declined and now I want to do it myself, however I don't know where the drain plug is located. I looke under the radiator and spotted a whited colored plastic looking nut on the passenger side of the radiator. There was also a nipple under it that resembled a grease fitting. Could this be it??? Or is it somewher else?? Any advise would be greatly appreciated!
Yes, the white nut is loosened to drain the radiator. I did as noted above: attached tubing to drain the radiator straight into containers. When tightening the nut after draining, I broke it like Kullamon. I think that I got a little overzealous using a wrench to tighten the nut (too much advantage). Be careful when retightening.
To get the broken nut out, I used a hex wrench that fit into the remaining nut stem (the threads essentially). I was lucky enought to back it out, redrain the radiator, and install a new replacement plug I picked up at Advance. The replacement design is better: turns in by hand and avoid the tendancy to overtighten (until it snaps!!).
