Puking After Coolant Bypass

[LoCo]

So I installed a coolant bypass kit a couple weeks ago, and now I'm puking coolant out of the tank. Not real bad, but enough to get some stuff wet and leave residue all over. I know having the tank overfilled can cause puking, but after the bypass kit I never added any. It seems to be putting coolant back into the tank faster than the truck takes it out, so the level is always a little higher than what it used to be. Prior to the bypass kit I had to puking at all no matter how hard I pushed it and I imagine if I closed the valves it'll stop puking. Anyone else experienced this or have any ideas?

I don't wanna sound like an idjit, but whats a coolant bypass, were does it go? I can help you a little better if i know this.

Make sure you haven't put too much water in the overflow, it needs to be at the MIN line.

Truck doesnt overheat or anything, eh?

Check the rad cap, too. Maybe it went for a **** - coincidence is a ***** sometimes.

Coolant Bypass Filter kit, it T's into the heater core line, out to a filter then T's back into the small line going from the top of the radiator to the front of the overflow tank. Definitely isn't overfull, I expected it to be low after the little i lost during the install and the amount it takes to fill the filter up, but it stays high with the return coming from the filter all the time. Coolant stays around 189 cruising, so no overheating problems. I was gonna pick up a cap while I was at a dealer in Jerzey yesterday, just to eliminate that as a problem. But their customer service skills there suck, so I left without it!

That's unusual that that would cause this to happen. Do you have some more info on the setup so I can research it a little more and determine if this is contributing to your concern?

I would almost have to think this is contributing to it - since it's only started doing it after you put it on.

Here's the kit I used:

Mike, when you installed the coolant filter, did you loose a bit of coolant, causing you to refill the degas bottle? If so, does your degas bottle have the new MIN/MAX level stick on there? Either way, my very first thought would be a overfilled resivior. Our trucks seem to puke to the desired level and then they will be fine, if it pukes, do not add any more coolant, just clean off the residue and keep a eye on the level, my guess is it will stop after the level goes down.

I'll assume you're asking me...

I did lose coolant and expect to be low, but I was not low after a short drive so I never added anything. I keep watching for the level to be low but it keeps puking and is still at the same level once it warms up. That is why I figured it's returning to the tank faster than its being used. I thought about closing the ball valves part way to see I it helps.
