I've bought some hose covering for the winter, those long pipe covering for about 5 bucks. In addition, aluminium foil tape like material. I've wrap both the high and low side as far as I could. Yup, I does cool the the car down quite a bit.
Also, try to hose down the front radiator and condensor at least once a week with a garden hose..my old mechanic taught me. You'll be suprise these overlook area.
