Coolant Resevoir Vent question

[ginger]

any air effects the cooling system.  in most peoples applications it wont make or break them.  but it does effect it.

I can’t run a remote res. I have a small battery pack/reg behind my tank and my shock res mounted up front hidden under the front Plastics... and all the damn wires they give you for the rigid light bar. Not to get completely off topic, but my Serval is being ported right now. When I go to fill the coolant, do I purge from the water plugs, then top off coolant level? From there I guess I can run the single tube off the neck and let the excess overflow....considering the majority consensus of the coolant res is not necessary.

Just fill radiator, leave the lid off, start the motor, wait for any large bubbles to work their way out, fill again, put the lid on.

Thank you!

I've taken every coolant tank off of my Banshee's (2) and any friends Banshee's (4-5 or so) that I have ever helped them work on. Never had a problem with any of them. It did actually help one time because I found I had a blown head gasket because my boot got wet near where I ran the overflow hose.

It is basically a catch tank not a resivore.. tell me how the coolant can make it back into the radiator from the resivore? Does it lift the seal on the cap to put it back in? The coolant expands once heated, lifts the seal on the cap and pushes it out the overflow until it get to level at operating temp. There is no way for the coolant to get back to the radiator unless it can lift the seal on the cap and push it back in, and the cap doesn't work that way.. jmo

its been a while since ive seen a standard banshee cooling system but i think it works the same way as a car. with the pressure differences it can push fluid out of the rad and pull it back in. if the overflow was nothing more than a catch tank there would be no reason for a hose to be in the tank bottom

Sorry to say but it IS a recirculating system.  The cap has a smaller spring/valve that allows the coolant to be drawn back in when the system cools and creates a vacuum.

Thank you.

But is that a banshee cap?

another give away that its a closed loop / recorculating system is on the recovery bottle theres a low and full mark if i recall. there would be no reason for these marks if it was a simple catch tank

[Keno]

Ohh, cool, never knew that about the caps. I knew it would draw coolant back from the reservoir, but didn't know how.

Mine does have that small valve, yes.

Instead of me continually trying to convince most people here that it is in fact a recirculating system,

go get one off your Banshee and suck on it.
