I bought a cheap sud a few days ago. I'm planning on using it as a cheap run around car as fuel prices continue to rise. Its running quiet hot in that the thermo fan comes on and rarely shuts of once the car is running. It has air con so I was going to pull that out in order to get some more air flow through the radiator. Guess what? To my surprise when I turned the air con switch on it actually worked! Anyone have any good suggestions to get the engine to run a little cooler with all that air con junk in front of the radiator?
