It's 10F outside and the radiator on my 98 G Caravan decided it's time to leak. I spotted the leak when walking out of the local grocery store and confirmed my suspicion (that the puddle was mine) on my driveway. After crawling under the van with a flashlight and rag, I confirmed that the drain plug is the culprit. The plastic plug looks like a spigot with a blade-style handle to torgue and a small pipe at the bottom. I could see the coolant in the pipe. So, I took a small wrench (adjustable; making it fit the blade) and gave it a small tug to see if it was loose. It felt tight. Rather than apply more force and possible breaking the part worsening matters, I left well enough alone until I could educate myself on the design. It seems to look like it would be a screw style fitting (male) going into the female end which carries the small pipe and some style of taper would create the seal. I searched on the internet but cannot find a good picture of the part. Maybe a trip to the local parts store may help. If we would have better weather, I would take the chance and just go for it but standing out on this frigid weather and getting into trouble is not what I want to bargain for. Do you fellas have any thoughts on this situation? It looks like an easy fix otherwise (except for the draining of the radiator).
