I was doing a radiator flush last night and took my overflow bottle off to clean it out good. I noticed some weird tape around the bottle which I assumed marked the "full" line. Welllllll it didnt. That "weird" tape was there to seal a tear in the bottle above the full line. So for now I just used duct tape around the bottle to cover the hole. First question is will having a hole in the upper portion of the bottle effect the "closed" nature of the coolling system or should I replace, maybe the duct tape will be sufficient but I dont know. Second, who makes our recovery tanks so I can replace it (besides Jeep at 45 dollars!). Seems like the TJ's are hard to find if at all but all models before ours are everywhere.
