HELP!!!!!!!!!!!!!!!!!
 

So today i open the valve under the radiator to change my coolant but only a few coolant came out. When i check the coolant tank it was still full. I tried using a pressure tester to force it out but no luck. Anyone know what might be the problem??? a clog somewhere??? I really need help. Thank you.

I've had a similar problem except with a fuel tank, and on an 1/8th scale Nitro R/C monster truck, but still the same thing. I started the thing up and it all of a sudden leaned out and died. I checked it and nothing was getting through. I tried blowing on the fuel pressure line (like a fuel pump in R/C cars I guess) to get the fuel to come through but I couldn't even do it. It eventually started working, but I lead to say that it was a clog somewhere in the system.

I would try really cleaning that thing out with something safe, yet something that will break down buildup inside of there. Good luck with your problem, I hope you figure it out soon!

take the hose clamps off and just pull the whole rad out. then you can dump as much of the coolant into a bucket or something as possible, then flush it with a garden hose or something. if its really bad, you may need a new rad. that sucks though, you can probably clean it.
