I feel your pain Robin, I just had my truck overheat on me yesterday while meeting a friend half way to pick up a couple of baby snakes. I had noticed the day before that the gauge was showing it running hot so I filled the reservoir, the next day the truck overheats and the reservoir is still full. Fortunately I pulled over in front of a car wash so I was able to get water. Three trips with a half gallon jug that I had in the back and the radiator is full again (reservoir never changed) It was at least enough to get me back home, I had steam coming out from under the hood by the time I pulled into the driveway. Took it in to the garage today and I need a new radiator and have the coolant system flushed out because it's all gunked up, which is why the water never made it from the reservoir to the radiator. It'll cost me $550.00 for all that when I finally get my truck back. At least thats what they told me on the phone, I hope it's not more. I really stinks being without your wheels, you feel like your chained down.
