OsuMj Posted June 6, 2013 Report Share Posted June 6, 2013 Ok, I drained the coolant, sent some DI water through it, closed it up, added a little over 2Qts of coolant (my bike takes 2.9 Qts). I know my next step is to start it up to make it bubble and get all of the air out of the system, but how hot do I let it get? Do I just let it run until there are no more bubbles? Honestly, I can barely even see when its bubbling because my air intake sits right on top of the radiator lid, but I was just wondering how long to let it run. Thanks!

jbot Posted June 6, 2013 Report Share Posted June 6, 2013 fill with your choice of coolant, put cap back on, rev engine like a squid a few times, open it back up, add more coolant, close, rev, open, add, rinse and repeat til the level doesnt go down any more. if you let it get too hot while doing this, when you open the radiator cap, you're gonna get money shotted (I speak from first hand experience, you do NOT wanna get bukkaked by your bike). once you're reasonably sure it won't take more coolant, open up over flow reservoir cap, add coolant til somewhere between low-high line and ride off into the sunset. 1 Quote Link to comment Share on other sites More sharing options...
OsuMj Posted June 6, 2013 Author Report Share Posted June 6, 2013 ok, that's the part that's freakin me out, what is too hot? I don't want hot coolant to burn me! I probably just need to suck it up and handle it. Quote Link to comment Share on other sites More sharing options...
jbot Posted June 6, 2013 Report Share Posted June 6, 2013 you don't have to rev it or run it for very long. just fill it, cap it, turn it on and rev it a few times. then turn it off again to check. your bike shouldn't run long enough to get it to burninator temps. just do that a few times til the level stops dropping. once you're at deals gap, you can have someone check it and add some more for you if you're paranoid. this is not worth losing sleep over. 1 Quote Link to comment Share on other sites More sharing options...

Gixxus Christ! Posted June 6, 2013 Report Share Posted June 6, 2013 I just leave the cap off while revving. The system isn't hot enough to pressurize and it shouldn't burp hard enough to spit coolant out. Quote Link to comment Share on other sites More sharing options...

Medina Posted June 6, 2013 Report Share Posted June 6, 2013 You have to get it enough to open the thermostat. thats typically where the air gets trapped- Quote Link to comment Share on other sites More sharing options...
