My buddy has a 94 Vmax 600 and he drained all the coolent out, and now he wants to re-fill it but hes worried about the air bubbles or air pockets in the lines affection the cooling, so is there any way to get the air out or does he just have to fill it and run it for a while then top it off????

thanks
 
There should be a bolt in the rear cooler that can be used for bleeding the air off. Be sure to fill the overflow bottle to the max mark and keep your eye on it.
 
It needs to be bled properly. Should be a bleed screw or two somewhere, someone on the board will have better information than myself.
 
If the 94 600 is the same design as what is current, and he has the rear cross over hose at the back of the tunnel, or a rear exchanger, this is where you can get air bubbles.
Run the sled, make sure that the thermostat has opened, lift the front of the sled so that the rear of the seat is no longer the high point, apply some throttle, but not enough to engage the clutch, repeat a time or two. Now lift up the right side, apply throttle a few times to move some water, set the sled down and do the same to the left side. Now lift the front one more time, a few runs of the throttle and then open up the bleed screw until collent flows put. Tighten it back down, let the sled cool and top it off. I do not know this sled, but this is what I had to do in the bad old days with my Polaris. I got this info a couple of years ago from www.hardcoresledder under the Polaris tech. section.
good luck 2datrl
 
Toward the end of the explanation, it's "coolant flows out", not collent flows put. sorry
 
Don't you raise the rear of the sled so that the air can come out the bleed hole? That's the way that I have always done it on my sleds.
 
There should be bleed screws on both flanges on the top of the rear heat exchanger. You need to take the bolts out of the trunk so you can lift the seat to get to them. Raise the back of the sled so that it's the highest point so the air bubbles will rise to the bleed screws. Slowly fill the coolant until the air bubbles stop coming out and it is all coolant. Also check the water pump for an air bleed screw, there should be one somewhere. You run the risk of melting the plastic water impeller in the pump if there is an air bubble in there. Start the sled and run it for 1 minute. Then bleed the system again. If there are still air bubbles coming out, repeat the procedure.
