Bleed radiator?

[BigMatt]

when you have to drain the coolant and fill it up do you have to bleed it like on a car? I swapped out for I high flow impeller and was wondering if I have to bleed it or will the air just work it's way out? thanks, Matt

Just to be safe i let it run for a couple min. with the radiator cap off and then top it back off as needed. but no they are not as picky as cars u dont have to bleed them just let it burp its self and call it a day

ya like mentioned above just run it for awhile with the rad cap off.

Always top it off with the motor running. Otherwise you can get an air pocket in the impeller and it will just cavitate.

The small hose is on top of the head is there to prevent air collecting there.

 

There is no way possible to get an air bubble at the impeller that will cause cavitation.

No you dont have to bleed the radiator. You only have to bleed radiators on cars where parts of the cooling system are higher than the coolant fill neck. All the air in the banshee's coolant system will work its way to the filler neck.

I just fill mine up. Put the cap on, rev it a couple times, take the cap off and top it off. Then run it up to operating temp ( just ride it). Then check the coolant level after the first ride. By that time all the air should be worked out.

i just saw a one bolt on each jug kinda in the middle of the jug and was not sure if this was to aid in bleeding.

No those drain the coolant from the cylinders and head. That way if you need to pull the head you wont get coolant down in to the engine. Cause when you pull the hoses off there is still coolant in the cylinders, and a little in the cylinder head.
