Pressure testing Nytro cooling system.

I recently had a leak and just couldn't find it. I purchased a Mityvac MV4510 Motorcycle Cooling System Test Kit and it fit the radiator neck perfectly and also tests the (radiator cap pressure release). I was able to locate the culprit a loose hose clamp (not real loose just enough to allow a small leak when hot) just tightened a little and good to go. This kit can also test for head gasket leaks when running just follow the instructions that come with it. One thing I would mention is make sure connections are tight on mityvac pump end and the radiator cap test end hose connections (by hand only on plastic nuts). Ensure cap on radiator neck is turned all the way until it stops. It should hold pressure if no leaks for at least 5 minutes or longer. I let it sit overnight at 14 psi and next morning it was 12 psi and no leaks. (I think some air will leak back thru pump overnight). Thought this might help others who need to know what fits the Nytro radiator and it also fits many MC,UTV,etc.

Good intel... hard to find these kinds of leaks, thanks.

I did a lot of surfing trying to find something that would fit. Thought sharing with others save them the time.

Thanks
