I just installed two 7" cooling fans under the louvers of the rear deck...They fit perfect and move 1100 cfm each. Also because of the louvers it expells the heat better than i thought they would. My engine temp is fine except when in stopped traffic...city driving. I have blown out my rads and just had them flushed out. I figure get rid of the heat before it builds up and it will take load off the radiator. The fans only cost $25 each.
