It's old school, but it's worked for me.

X2 This is how i always do it also and it has always worked for me too.
The pics above are to show you what the others are talking about.

adantessr I always do as two of the other posts have mentioned . Drill a hole in the flange of the thermostat . I used to drill a bigger hole than I do now . One 1/8" hole works for me and still lets the engine get up to temp quickly . Go bigger if you like but do drill a hole .

scholman jls4speed,

I have seen this happen more times than I can count. Replace the thermostat and it will be good to go. You can take it out and run it to see if the problem goes away if you want to test the theory.

jls4speed motor isnt over heating after a half hour of running. tstat cant be stuck closed

V8 Super Beetle Did you just fill the radiator before you started the engine and haven't topped it off yet? I would've filled the rad, left the cap off, let the engine run until the t-stat opens or until you see some steam, then top it off and cap it.

scholman jls4speed,

I think the thermostat is stuck in the closed position. When the engine is shut down the heat builds up and you hear that rumbling sound.

jls4speed is this the only way to purge the system or will driving it just do it
09-27-2010 06:49 AM
sunsetdart you want tp drill 2 holes in the t-stat. drill 1/8" holes on either side of the flange that sits on the manifold.make sure the holes are 180 degrees from each other.
the overfow has nothing to do with air in the system, it is for expansion of hot coolant after the motor is shut off .

jls4speed drill into the intake? or drill into the tstat itself? i have my overflow hooked up wont it just eventually burp it all out after running it for a while. i already ran it for a half hour for the break in.

DoubleVision More than likely just air purging out of the system. To aid the burping of the system I always drill one 3/16 hole in the parimeter of the thermostat.
