i want to get the air out of the system, i have a rear heat exchanger, but no bleeder, i filled the system ran it until hot, took off the heat exchanger hose, anti-freeze came out, then i topped it off with coolant and opened the bleeder on top of the carb heater on/off knob and the anti-freeze won't come out, any help would be great thanks
 
Prop the sled so that you ante freeze/coolant fill cap is higher than the rest of coolant system... and rear heat exchanger, start sled, leave coolant cap off, let run, small throttle blurps, you should see air bubbles coming out in tank...add anti freeze as needed...make sure all heat exchangers are warm.... top off system, and run. check level after it has cooled off.

Thanks, i have the front end up, it is higher, should there be anti-freeze come out of the bolt that is on top on the carb warmer on/off knob, it does seem like there any anti-freeze in the clear tubes?
 
Dont know what clear tubes your speaking of, But, put the bolt back in loosely...so it stays and doesnt fall out, leaving the cap lets the trapped air escape...do that first. with the sled running, then check the bleed bolt in the rail you should see anti freeze coming out..

Right where the knob is to turn on carb heaters, that bolt, turn the knob to ON position,

thanks everyone got it bled, what a nightmare with no bleeder in the rear, next year will be adding one, thanks again
 
I had the same issue with my viper. There is a bleed screw on the cooler. Who ever installed it neglected to drill a new hole for it. I took a chance with mine and drilled for it without removing the cooler. The tunnel has enough flex in it that you should be able to feel around for the screw. Once it is located use a small hole saw and drill a hole in a piece of ply-wood. Next remove the pilot bit from the hole saw and clamp the wood template to the tunnel. You should then be able to carefully drill a hole around the bleed screw.
 
My '02 viper didnt have a rear heat exchanger/cooler. I bought one from a guy on this site. It most definately has a bleeder! The crossover pipe that came stock with my viper had one on the right of center on the top of pipe. The only way to access this bleeder is by removing the seat. The cooler I bought has a bleeder on the left of center (looking at sled from back). You need to find the center of the back of tunnel, and then follow the steps provided earlier with hole saw minus pilot bit. The new hole should be same distance left of center, that the original one is right of center. (on an '02 Viper)
 
yep even the crossover tubes had a bleeder,shark yours is probably hiden by the tunnel if someone changed it out at one time,need to drill a hole.
 
i know the rear heat exchanger was added, but the coolers on the footwells are stock, where do i even start to look?
 
Remove the seat. All the way at the back of the tunnel on the top, there should be a hole. maybe a 1" hole. If you dont see a bleeder valve, It will be the same distance towards the other side of the center of the tunnel. YOU HAVE TO REMOVE THE SEAT TO DO THIS. 2 nuts on the outside edge of the trunk are all you need to remove to take the seat off. either a 10mm or 12mm nut, cant remember which. From there, follow the instructions posted earlier on how to bleed the system. If you are handy, this should not be too difficult. good luck.
 
When you have the seat off, start pressing hard on the tunnel in the area you suspect the bleed screw to be. There is enough flex in the tunnel that you will be able to feel where the screw is located. The only other option is to remove the cooler and measure properly. I was too lazy to do this and managed to get lucky with the method I described a few posts earlier. If you are able to determine what cooler you have (SRX, Bender etc..) I could send you photos with measurements.

I would be concerned that there is still air in the system if you have not followed the complete bleeding process. Also, the carb on~off switch needs to be partially removed to bleed the system at the head.
 
good news and bad news i found the hole, but there was no bolt, just more sheet metal so i slow and carefully drilled and it hit the heat exchanger, so now i have a tiny hole there, can i seta screw in there and maybe silicone it or a self tapping screw? any help would be great thanks
