I was taxi'ng out on the runway this evening testing a new tail wheel leaf spring I just installed. The temp outside was about 92 and hot. My 582 was overheating and runing on my taxi test at about 205 degrees.

On recent flights I was running I thought a little "hot" at about 150 - 160 on take offs and it would settle back to red line at 140 on straight cruise.

I am looking for ideas to improve cooling. I have a radiator under the cockpit. I've been told several thing to lower the operating tremp from buildind a air intake surrounding the raditaor, taking the thermostat out, lessoning the coolant in the radiator and adding more water to lowering the radiator a 1/2 - 1" so it it isn't fluish with the bottom of the plane. Any ideas?

Call me at 317-506-2854, Thanks ... Keith
