Coolant Reservoir Tank Keeps Emptying While Riding.

[HeavyHauler]

  What’s up fella’s!! So I have been riding my Banshee for the past 2 days here with my friends and the outside temps have been in the 60’s with no humidity. I noticed that the coolant reservoir tank keeps running dry but the radiator level is perfectly fine. I don’t think it’s getting hot enough to overheating either. When I let it cool down and remove the radiator cap it makes a slight pop sound from releasing the pressure. I spent last night checking the complete coolant system for any type of leaks and didn’t find any hose clamps loose or out of place. I even removed the reservoir tank and blocked off where the hoses connect to the reservoir and filled up my kitchen sink with water to see if the reservoir tank has a leak and that was good. I then refilled the reservoir tank with 50/50 mixed coolant and then warmed it up and then let it sit and run idle for about 20 minutes and I even revved it up a little bit and nothing was leaking then I looked to see if there were any bubbles backing up in the reservoir tank and I didn’t see any bubbles. Then I checked to see if the coolant was leaking into the transmission and mixing with the transmission oil and that was perfectly fine. I pulled both spark plugs and they both are fine and are a light tan / coco color. I’m sitting here scratching my head trying to figure out what the heck is causing this issue. Here’s my question. Is this a common problem with Banshees or is there something else wrong? 

Thanks,

You can just ditch the tank completely. As long as the radiator is staying full, you're good. Just run the hose that goes to the tank straight to the ground.
